Transmission Oil Review

[slider2828]

Well I just switched to Amsoil over the weekend.

Man Amsoil is the best! 75w-90 althought like 15bux a quart, but the best stuff....

I went from cheap gas station stuff to Red Line Heavy Duty Shockproof to Redline MT90 and hands down Amsoil pwns all of it. Shockproof was bad cold shifting just like the MT90, but Amsoil... is unbelieveable cold shifting was not a factor....

I just really suggest it. Most people say stay away from Royal Purple and after using their engine oils, Amsoil Signature> Amsoil > Redline > Royal Purple > Mobile 1 = Castrol GTX > Valvoline.....

Just thought you guys know since there was a couple of discussions on this.

[JRas]

I'll have to try it next time

I used some Redline MT-90.. wouldn't really recommend it though

[clark]

yeah i used redline mt-90. i'm honestly not happy with it right now.

i'm gonna try amsoil then.

thanks for the review.

[420sx]

wow guys. i ran mt90 for years in my track car and i LOVED it. smooth shifts, last a while. shockproof is great if you track your car. redline mt90 is one of the best out there for SR/KA trannys imho. never tried amsoil, just couldn't justify the price tag. im glad you found something you like more though

it's good when warmed up, but when cold, it could be better...

[KA240SX808]

I'm using the Royal Purple Tranny oil and not real impressed w/ it, feels just like it did w/ what I had in it before, what ever that was :p

[slider2828]

Yah cold shifting with Redline is pure crap.... Its just too bad cause I love their engine oils, but I changed over with Amsoil, best thing for a tranny ever!

[I10cruiser]

how long do you guys keep royal purple in the tranny before changing it?

[dex]

stoopeed question... how many quarts do you need? =)

[Monooxide]

2.5 Quarts for SR transmission.

If you like Amsoil transmission oil so much you should try out their engine oil too.

I personally run Rotella 15W-40 Diesel oil.

[dex]

Thanks... but... diesel? what who why?

[240trainee]

It's just oil, but the weights are a good compromise between heavy and light weight automotive oils.

and I think it has less detergants and shit in it, I could be wrong.

[420sx]

its really cheap too

[Monooxide]

Thanks... but... diesel? what who why?

With new emissions standards oil companies have been asked to lower the amount of certain chemicals/compounds in their oils.

However the Shell Rotella has kept the highest percentage of these detergents by over 200-300% more.

- What is Triple Protection? (http://www.shell.com/home/Framework?siteId=rotella-en&FC2=/rotella-en/html/iwgen/press_release_2006/zzz_lhn.html&FC3=/rotella-en/html/iwgen/press_release_2006/cj-4_triple_1006.html)

Heres more information on the anti-wear chemicals such as ZDDP that they still use.

Shell Rotella is one of the leading suppliers of oil for turbine engines, I know the kind of abuse they go through and it requires a very decent oil.

[slider2828]

In generally tranny oil doesn't get changed for a lot of miles. The FSM will tell you but I think like 20k miles or something if not longer. I dunno about Royal Purple, their gear oil felt just like any other oil except at a premium price. Their motor oil I would say is better than Mobil1, but has the same longevity as Mobil 1 which is liek 1500 miles on a 350HP SR.

I use Redline Egine oil which is 1 dollar more than RP and Amsoil is about 2 and Amsoil Signature is like $3.50 more than Redline. Personally Redline performs well as an ENGINE OIL. But Amsoil Tranny oil is LIQUID GOLD....

Just like this guy

http://cmogen.com/sc_blog/wp-content/uploads/2008/04/got_milk.jpg

[Matej]

Hah, I run the same oil in my transmission that I put in the motor, 10W30 synthetic motor oil.

[slider2828]

Hah, I run the same oil in my transmission that I put in the motor, 10W30 synthetic motor oil.

You serious? But during certain conditions the thing will heat up and turn to water like crap... reference to tranny

[Matej]

Yes, it's been in there for about two years, haha.

[slider2828]

Wow livin on the edge....

[Dousan_PG]

not really
most daily cars dont have the trans oil changed for years on end
sure it probaly should be changed but its not terrible if it hasnt been

anyways
i always use redline MT90 on my 240sx transmissions and with great success.

[karl wasabi]

I can never tell the difference when I change oils. I've run MT90, generic shit, Torco, and now I'm using Royal Purple. Can't tell the difference. LOL.

[SoSideways]

Redline MT-90 in my tranny for the last 2 changes, and the last time I changed the oil in there was.... maybe 2 years ago? hahaha

I already bought 3 qts of Amsoil tranny oil back when I was doing their "preferred customer" program, but never bought enough of their oil and stuff to justify keeping on it, so I just let it run out... haven't bought anything from them since.

But yeah, a buddy of mine put some Amsoil tranny oil in his S2000 and said it was the best stuff ever, not that he has tried other stuff, so I have no clue.

I'm about to change all my crap out though... maintenance day coming up...

[coww-cho!!!!!]

when i got my car it shifted horrible then i tried lucas tranny fluid and i love it so far havent tried any other

[Matej]

Wow livin on the edge....
To be honest I was pretty sure my transmission was going to go out soon, it was starting to grind and sometimes wouldn't shift into 1st or reverse, plus it has a leak. So I stopped worrying about it and instead of topping it off with transmission/gear oil, I just started topping it off with motor oil since I'd always have some left over after an oil change. I assumed the transmission would be done for soon anyway.

Surprisingly, it's two years later, and my transmission functions better than ever, no grinding, and shifts perfectly, haha.

However, don't get me wrong, I didn't just decide to pour a random fluid in there. I started doing it after I found out that many transmission fluids are 10W30 or close, and even some race cars are running motor oil in their transmissions, so I'm guessing it can't be all that bad.

[g6civcx]

Borg-Warner T5 calls for gear oil or ATF. I run ATF.

[Om1kron]

i'll give amsoil a try on my fluid change.

[DeadlyZ33]

I highly recommend Motul transmission fluid, some of the most expensive I think but I noticed an improvement switching from mobil1. It is supposed to be good for smoothing out notchy feeling trannys like the z33 has, shifts like butter now. I also believe its recommended by subie owners because their trannys are notchy too.
Plus nissan uses it in all their race cars so what the hell.

[racepar1]

I use neo 75w90HD or neo 75w90RHD. The HD is about $40/gallon or so and the RHD is about $80/gallon or so. I LOVED the RHD, I have the HD in it right now and I don't like it so much. I'm gunna switch back. The royal purple tranny oil is quite good as well. My buddy switched from the NEO to the royal purple in his trans on his XB and he said that it shifted a bit smoother. The royal purple synchromax fluid is dope if your trans calls for low weight fluid, like ATF.

As for motor oils the diesel oils are the best, especially for motor break-in. They have a LOT more detergents and suspend particles much better. For break-in I would run a 15w40 non-synthetic diesel oil and after that I would run a 10w30 synthetic oil. Synthetic oil stands up to high temps MUCH better than natural oil. Since I track my car regularly that is VERY important to me. I like royal purple, but I wanna try some different stuff. I run royal purple 20w50 generally because my motor is so old and has so many miles on it. Right now I am running some 10w30 castrol syntec that I got for free and I am not very impressed. The motor seems even louder and clunkier than it was with the royal purple. I may try some royal purple 5w20 racing oil that I also got for free for my next event this saturday. It should free up a bit of power.

mobil1 transmission fluid blows ass so hard it's not even funny, it would be no surprise that motul ran better, whilst also being a shitty tranny fluid.

[racepar1]

mobil1 transmission fluid blows ass so hard it's not even funny, it would be no surprise that motul ran better, whilst also being a shitty tranny fluid.

:werd:

Mobil one is the WORST tranny fluid you can put in our trannies. I tried it once. The trans ground like shit once it got hot. I changed the shitty mobil one crap out with some cheap ass regular gear oil the SECOND I got home.

Mobil one makes you and your trans ghey, it's the troof!

[DeadlyZ33]

LMAO troof. I remember after putting mobil1 in after changing the tranny oil for the first time in my cars life it felt like a downgrade. Needless to say I swapped to motul long before it was required.

Still hear motul is one of the best out there though. Made my tranny feel new again.

[Om1kron]

it has aids... I put it in my old civic and I couldn't even drive it until it warmed up and it just felt like I poured butter in my transmission and not butta!!! it made me cringe to change gears, i went right to the dealership and bent over for 3 quarts and changed it ASAP!

Well its right up to Amsoil which is 15 a quart for gear 75-90... Royal is ok, its like an on and off switch for oil. It protects, then just breaks down real quick... I really suggest Redline oil, usually a dollar more but a WHOLE lot better...

[KA240SX808]

So what would you guys recommend?

The AMSOIL Syncromesh 5w30 or there Synthetic 75w90 GL-4 Fluid?

[slider2828]

Amsoil is 75w90 GL-5 if you read the back of the package. Definitely Amsoil.... hence opening poster.... lol

[98s14inaz]

Redline MTL for mine. I used Redline MT90 for a while but it didn't care of the cold much.

[design240sx]

whats a good brand tranny fluid for daily driving sr? from a cold weather?

[blueshark123]

im surpised that no one mentioned gm syncromesh i havent had any problems in my car or my brothers k20 with 650whp

[Bubbles]

I use redline, doubt I'll ever use anything else.

[DJ_Sunrise]

Ive tried RP, Redline, Mobil 1, and some other shit. Mobil shifts like shit... it's horrible. Royal purple was ok. Can't remember any details.. so it wasn't shitty, or great. But I have tried Redline shockproof and MT90. Both were amazing. If you complain about how hard it is to shift, grow a set of balls. It's supposed to protect your tranny. By the time your engine warms up, the trans fluid should be warmed up too.

-Bart

[Om1kron]

lol i like that, grow a set of balls.... ram your stick into the gates when it's cold, whats a little grinding right?

[superJoy]

Just an FYI, you're not supposed to use GL-5 in our KA/SR/CA/whatever transmissions

FSMs all call for GL-4

Most people already know that, because they say they're running MT-90. Which is GL-4.

Mobil/Valvoline/Pennzoil that you get on the shelf is all GL-5, which is a different mix of additives than what we need, and (apparently) cause issues with the synchros. So don't use it. People have wasted a lot of time on the Internet arguing about whether it's safe to use GL-5 in our transmissions, so not really going to beat a dead horse. Just play it safe and stick w/ GL-4.

Reason I say all this is because I had a transmission leak and decided to fix it, so I had to drain out my old MT-90 and search all over town for a GL-4 fluid. Eventually found some at NAPA, plain old non-synthetic stuff, made by Sta Lube. It's 85W-90 which is a little thick but shouldn't be an issue in TX.

Redline MT-90 is ideal for our transmissions, I just couldn't find any locally and I gotta have a car to get to class tomorrow. Sucks living in BFE sometimes...

[design240sx]

well i just went to the store and bought some royal purple stuff. ill let you know how it feels!

Pennzoil has a 80w-90 GL-4 (http://www.pennzoil.com/products/gear_oil/index.html#GearplusGL4), and it's good stuff, better then RP IMO

I run 10w40 redline oil and my KA is still noisy lol. I removed the top and side chain guides though and i have an intake (well u do too) with peak perf race tranny mount and cusco engine mounts... maybe that makes it louder heh.

That is correct, GL-4 is what we need in the tranny and GL-5 is what should be run in the diff.

The GL-5 has additivites that are not good for yellow metals (eg; brass which our synchros are made of)

[slider2828]

AMSOIL - Synthetic Manual Transmission and Transaxle Gear Lube 75W-90 (MTG) (http://www.amsoil.com/storefront/mtg.aspx) <---You guys can run this stuff,

http://www.amsoil.com/storefront/svg.aspx <--- but I run this stuff. So if you really wanna bitch at labels, then go do research and not speculate. It supports GL-4 and Gl-5

But like I said, if you want run the MT and Transaxle Gear Lube....

[JRas]

Let's see some proof that GL-5 ruins brass. That's all a bunch of smoke and mirrors bullshit man. It is the additive package that makes the oil better or worse. I used GL-5 oil all year last year and it was a shift fork that broke in my trans, not a synchro. I use NEO 75w90 HD or RHD. I then replaced all the forks with some out of a donor tranny and sold the trans. It still shifts like butter to this day. GL-4 or GL-5 doesn't matter, it is all about the additive package. I personally like to use oils from smaller companies as their additive packages are better engineered.

Why would Nissan recommend the use of GL-4 rated fluid in their transmissions but recommend GL-5 for their differentials?

intresting read:
Gear Oil Selection (http://www.ratwell.com/technical/GearOil.html)

Oils are made from base stocks, refined and then mixed with additives to improve their performance. GL-5's incompatibility is due to the extreme pressure (EP) wear additives. To give the gear oil its EP rating, it's easiest to add a sulpher based additive like MoS2 (molybdenum disulphide) but the sulphur present in the oil (you can smell it) is responsible for eating the copper alloy used to make the synchros.

GL-4 differs from GL-5 by the amount these chemicals are mixed into the oil (1/2 to much less in GL-4). Since the same additives are present in GL-4, they will eat the synchros as well but at a point in time that is beyond the expected service life of the gear stack.


To get the GL-4 rating, the oil has to pass the ASTM D-130 test. This test determines how reactive the sulpher is against a polished copper strip. The strip is also subjected to heating to simulate the running conditions in the gear box.

To obtain GL-5 certification, the manufacturer does not have to pass the ASTM D-130 test. This is the main reason why you should avoid GL-5. So, if you put in a call to a manufacturer about their GL-5, that test result is what you want to verify.Some people will claim that using GL-5 in a GL-4 spec transmission doesn't apply when the GL-5 is synthetic. This depends on the oil and cannot be generalized. However, it should be noted that many GL-5 synthetic gear oils do not use sulpher in their EP additive package and can pass ASTM D-130.Even if the ven if the manuacturer states the gear lube is "non-corrosive", its viscosity index may be too slippery for the VW style synchros. This means that while the syncros won't corrode, the oil is not designed to grab the hub the way GL-4 does and the transmission will wear out another way.As a final caution, some GL-5 formulas have been known to permanently coat the synchros in a VW manual transmission reducing its life by 50%.

GL-5 MT-1:

In recent years a new gear lube rating has appeared: API GL-5/MT-1. MT-1 all by itself is just as non-suitable as GL-5 can be but in combination some manufacturers when asked are now stating that formula is ok to use in place of GL-4. It is hard to verify if these gear oils are suitable for the transmission. Certainly, they have not done as much research as VW has done but at the same time VW is no longer testing new transmission oils with their obsolete models.
What is clear is that the oil has to pass ASTM D-130 to get the MT-1 rating. This will determine if their EP additive package is non-reactive with copper. However, until you try shifting the gears you won't be able to confirm if it's got the proper viscosity.
For that reason, sticking with GL-4 is simply the best course of action for long transmission life unless you can verify mileage and shifting performance with another owner.

[slider2828]

Awesome thanks for the post.... I will probably switch to GL-4 later.... Probably by end of 3 months..... Blah.... Amsoil makes great GL-5 oil... I will test the GL-4 in a couple of months no biggy, unless someone wants to test it for me and let me know. I am sure its really good either or..

[Om1kron]

gl-4 it is.

[SoSideways]

http://www.amsoil.com/StoreFront/images/mtg_qt_640pxh.jpg

That's the bottle I have 3 of. Same thing that went into my buddy's S2000. He said that shit is the bomb, and in the S2000 community they pretty much said it's the best for their tranny.

[shrug]

I'm gonna switch out my like, 2 or 3 year old Redline MT-90 or MTF (whichever one was slightly thicker) that's in my tranny now for the Amsoil stuff probably next time I'm under the car.

[slider2828]

That is right!....

Yah that is that crappy Heavy Duty Shockproof.... Junk!

[umsports]

Here's my mix for my KA-T.

1qt Royal Purple 75-90
1qt Royal Purple 10-30
1/2qt Lucas Transmission Fix

Call me crazy but before this I used to replace the tranny every 6-8 months. My current one has lasted almost a year and isn't showing any signs of giving up.

[Geno750]

I'm definitely a fan of the Amsoil stuff, I'm running the 75w-90 gl4 in my transmission, and 20w-50 high zinc Amsoil in the engine, and everything is running great.

[HemiCharger]

I like BG synchroshift 2 and it is all yellow metal safe....

[blownmotor]

I run Shockproof with a mix of MT-90 and it works pretty good when it's cold. I don't know why you guys say Shockproof is junk. It doesn't heat up like regular oil and the viscosity is high enough to not break down. Hell R32 and 33 owners swear by it.

[Zeller]

I run the Amsoil motor, trans and diff fluids in my s15 sr also. I am also switching over all my other cars too. I just became a dealer so if anyone wants some special pricing on these products just PM me!!

Blah blah blah, whatever. You said it yourself in your post. GL-4/5/6/whatever only matters depending on the manufacturer. I'll just ignore all this gl-whatever crap untill I actually have a problem. The neo 75w90 rhd that I am running exceeds gl-5 and gl-6 standards, but for some reason in the 1.5 years of track/street beating I have yet to have a synchro problem. IMO it is all bullshit and depends ONLY on the manufacturer. That opinion will not change untill I personally have a problem.

[slider2828]

^^^ I agree, but one thing I can tell you its smoother than all the shockproof redline stuff and that is my test and all I can confirm.

I use redline oil and that is all that goes in my motor, but from my EXPERIENCE Amsoil just made a better gear oil/tranny oil.... Done....

If there is more bickering about standards, I am going to lock this thread....

SSOOOOOO hopefully people can post up their experiences more.

I would agree that amsoil is better then redline for the trans at least. Shockproof is just too thick for our trannies andI have heard too many horror stories about the mt90.

[Somnambulist]

FSM says GL4 for trans and GL5 for diff.
Which stuff would I use for the trans?

Manual Synchromesh Transmission Fluid 5W-30
or
Manual Transmission & Transaxle Gear Lube 75W-90

The 5w30 doesn't say anything about GL4...

And for the differential? Quite a few different options..

Severe Gear 75W-90
Severe Gear 75W-110
Severe Gear 75W-140
75W-90 Long Life Synthetic Gear Lube
Synthetic 80W-90 Gear Lube

I'm getting a Cusco 1.5 way Type RS LSD in this week.. Wondering if I can use the Amsoil stuff or should I just stick with the Cusco LSD oil?
If I did go with the Amsoil gear lube, would I need the Slip Lock Differential Additive?

Severe Gear 75w-90 from Amsoil, but I would stick with Cusco stuff.... Never used the Amsoil for the Diff, so just Cusco and when you run out of Cusco just go amsoil I am sure its fine.....

and then

Manual Transmission & Transaxle Gear Lube from Amsoil. It says GL-4 right on it, go to the website as I have posted in a couple of posts back.

DOne and Done.

Hm. What about the LSD additive from Amsoil?

[essforteen]

I use Motul Gear Box 80w90 Mineral Oil. I cant tell the difference but seems to shift

smooth! I was told it was reusable and doesnt break down.

what do you guys think!

Reusable.. How so?

[Teambadrun]

meh i just use castrol vmx80.. does the job fine.

[slider2828]

I think its recycleable because its vegetable oil based, but I don't think its reusable as the additives would surely breakdown over time.

[SliddinSidewayz]

how many bottles of amsoil do u need for the sr tranny ? goona change mine today...

[NISMOTUNEDZ]

How would you be able to find the correct wEight for your tranny? Ive heard people using the same tranny oil for thier diff... Is this correct????

[95kat]

Im ordering the amsoil 75w-90 gl-4 now!

Doing a 5speed swap this weekend and might as well start off with the fluid no one has said anything bad about.

[soreballz]

I used to run MT90. It was nice at first, then my tranny started getting notchy... I switched to Penzoil Synchromesh on Friday, and it feels 100x better now.

[JaMeSoN]

now only if there was transmission oil that didnt smell like ass. I hate how I can smell it through my shifter :(

MT90 smells alright. Even after 16 months of constant flogging, it never started stinking. lol

[slider2828]

Amsoil smells least and Motul smells NICE!! Why? cause Motul's base is veggie oil. Yum!

[Mangudai]

What about autos?

[slider2828]

Look up on their website.... AMSOIL - Synthetic Oil, Motor and Engine Oil, Lubricants, Air Filters, Oil Filters and Greases (http://www.amsoil.com)

Never tried their auto stuff, but I am about to for my acura TL.

[White Comet]

nice thread and good info in here. i just swapped my sr into the new shell with a new (used) trans and was debating what oil to use. i'm def gonig amsoil now. i swapped in a ka trans with sr bellhousing, and before putting the bellhousing on i had to beat the shit out of the drain and fill plugs. the last owner sealed them shut. long story short, i had to apply heat and now need new plugs

[nismoskyz]

Some good info here... so Amsoil or Motul then?

My 3rd gear has been grinding ever since i got the car so a while back i replaced the gear oil with Royal Purple...

now i'm noticing that when its cold, the transmission shifts like butter in every gear, and i can even jam it into third without a chirp, but once it warms up, 3rd starts grinding as usual and all the gears, in general, dont shift as smoothly as they do when its cold.

What would be my best bet?

[INeedNewTires]

I use neo 75w90HD or neo 75w90RHD. The HD is about $40/gallon or so and the RHD is about $80/gallon or so. I LOVED the RHD, I have the HD in it right now and I don't like it so much. I'm gunna switch back.

This is what I use and LOVE it! besides, if SPL runs it in their race cars, then i'm sure its good enough for me.

As for motor oils the diesel oils are the best, especially for motor break-in. They have a LOT more detergents and suspend particles much better.

I thought alot of detergents on a race motor was bad? less lubricating molecules because of all the soap molecules right? Elaborate please


What about autos?

They fail....

Sounds like the RP is thinning out too much under temp, I'd step it up to a full synthetic oil, with maybe a bit higher weight like 80w-90.

[fliprayzin240sx]

K I need some input. My tranny's starting to grind 3rd gear, the wierd thing is it only does it when its wam and its only that gear. Im currently running RP 75-90, I got a spare tranny but I would rather change the oil first to see if that alleviates the problem. I figured since it runs better when its COLD, im thinking i should empty some of the 75-90 in there and toss a qt of 75-140 RP in there to ticken it up.

But people are talking about AMSOIL being the shit, only AMSOIL i found out here is 80-90. So Im torn which route I should try.

[nismoskyz]

@ineednewtires
could you suggest a particular brand/product though?

with all this talk about amsoil in this thread, I'm considering giving it a shot, but I'd really like to know beforehand if its possible that it will solve my grinding.

@fliprayzin240sx
lol, thats almost exactly the issue I posted about 2 posts up....

[Taniguchi_Is_#1]

a change of fluid might be enough in itself. i remember i used to grind 3rd in my s13, but after changing the fluid (from some accidental gl-5 to gl-4) the problem went away. go with any good fluid and if nothing changes, then it's not gonna be solved with oil.

[slider2828]

UPDATE!!! Lol funny you guys are talking about this. Man literally I tried all of the oils, and you NEED Amsoil for tranny.

Manual Transmission & Transaxle Gear Lube 75W-90 Product Code: MTGQT-EA

You can order via this site AMSOIL Synthetic Automatic and Manual Transmission Fluid (http://www.amsoil.com/a/synthetic-transmission-fluid)

I don't think they will ship overseas cause its oil maybe? If NONE of you guys can find some I have a local place that carries ALL of the lines of Amsoil. I can get it for you guys pack it and ship it. Place is called Vic Hubbard in Hayward, but like I said I can ship it if you guys can't find it.

Let me know.

I switched to this as I tried to the Sever Gear from Amsoil and this one is better.... I just did it over the weekend. Immediately noticed the difference.....

[jakerps13]

I'll say it to everyone I know who owns a nissan 2.4/2.0 manual trans, Lucas HD 85w-140.

[xtreme_s14]

Ummm.. Yeah, AMS oil is definitely the way to go motor and transmission wise. I've yet to try it on my Kaaz differential.. Anyone care to try?

Are you guys aware of AMS Oil's warranty? You guys should really read up on their stuff. If you happen to destroy your motor in belief that it was caused by their oil, they'll ask for a sample of the motor oil to check the chemical properties that they claim should not/will not harm your motor. (Something along those lines)

They're oil is supposedly capable of 25,000 miles or one year, whichever comes first. As much as I'd like to save myself some money, I still would prefer to change it at every 2,500-3,000 miles or three months, whichever comes first. Research their stuff, it's pretty interesting!

[nismoskyz]

@slider2828

So why'd you try so manny different oils, what problems were you having?

I'm down to give AMSOIL a shot but I wouldn't like to end up still having the same grinding problem afterwards...

I would think that an oil with a higher weight than what i have now (Royal Purple 75w-90) would be better since it would provide more lube for shifting

Thats why I'm just a little sketchy on switching out the oil for the exact same weight and expecting better performance. I'm not an expert on gear oil by any means though, so I wouldn't know if it really could make a difference...

To add to this I am a dealer and can have it dropped shipped right from the factory to anyone and my price will probably be better than the stores and I know it will be better than if you just go to the Amsoil website. Pm me for anything you need!

I always like lucas's transmission oil additive, and thought one day i would try their "lucas HD".... read below... But for you if you want synthetic i'd do the motul shock proof stuff, in an 80w-90, or the NEO RHD, but its 75w-90... depends on what you want to spend too, but if you add a bottle of that lucas additive it should smooth things out nicely. make sure you are filling it to the proper level and make sure your vent tube isint blocked or clogged as well.

I'll say it to everyone I know who owns a nissan 2.4/2.0 manual trans, Lucas HD 85w-140.

never Ever EVER run this shit! I tried it, and had to drain it 20 miles later, it would not let me in any gear, shit was WAY too thick, even after it got warmed up, trust me i'm in texas, and its plenty warm, and its NO GOOD for our trannys.

[Bigsyke]

Just finished my 5 speed swap (took 5 hellish days).

The tranny I bought was supposidly bad, so I was taking a high risk. I pulled the casing and saw the gears were worn, and I expected some heavy grinding in every gear.

Filled up with 2.4qts of amsoil 75w90 and it runs better than new.

Royal purple WILL kill your tranny

[fliprayzin240sx]

Nah, I changed the oil already. This RP is only about 1 month old. Maybe it just fucking sucks...:rl:

[tinys s14]

im almost dun with a 5spd swap n need gear oil so i got valvoline 75w-90 since they was no redline or amsoil. just wondering if its good or not or I shouldnt be cheap n buy some royal purple for 17 a quart

[scuba_steve91]

Amsoil tranny oil got rid of my 2nd gear grind. I love the stuff.

[drift freaq]

I used to run Amsoil in my 90 Hardbody pickup KA24E. Changed it out every 24k had the truck from when I bought it till 130k, it ran great when I sold it. I will run Amsoil in my HR VQ as well.

[nismoskyz]

Wow, some pretty strong claims towards AMSOIL.

i think i'm sold.

I guess I'll go for the 75w-90... I pray it works out and solves the 3rd gear grinding... we'll see then.

[fliprayzin240sx]

Same here, i just grabbed 3 qts of AMSOIL 80-90...$9.50 a pop, cheaper than RP which cost $15 a pop.

Anyways, Im gonna change my tranny oil tomorrow and install my Peak Performance Tranny mount...ill post up again with the outcome if this oil made a difference on my tranny.

[ZenkiKid]

I had an occassional 3rd gear synchro grind before i changed my tranny fluid, then i switched to royal purple and the 3rd gear grind happens every single time i shift when the oil gets warm. I hate it. Im thinking of either going mt-90 or just buying the nissan oem fluid

[Bigsyke]

Why 80-90? I didnt even know they sell this weight. It's not on the amsoil.com website at least.

I was gonna pick up the "Manual Transmission & Transaxle Gear Lube 75W-90".

It's $12.85 a quart on their website... Unless Zeller gets back to me with a better deal.

Although I'm no expert, if I were you I'd pick up the GL4 stuff, just to play it safe, since that's what Nissan recommends.

[nismoskyz]

So I swapped in the AMSOIL this Sunday...

Unfortunately, :( , I'm not as impressed as I thought I'd be.

Don't get me wrong, it's definitely much better than the 20K old Royal Purple it replaced and shifts are noticeably smoother. However, the primary goal/expectation of mine was that it would remove my 3rd gear grinding, which it didn't.

Grinding does seem reduced and, just as before, when shifting cold, grinding is entirely nonexistant (such a teaser!), but once things warm up, the grinding comes back as usual.

Nevertheless, the rest of my shifts do seem much smoother than before, so that's nice.
Also, it seems that once the trans warms up to a certain point, shifting becomes noticeably difficult in every gear. I was having the same issue with the Royal Purple I had before.

Now, is there any possible way for me to get the trans to shift as well when its warm as it does when its cold? A thicker weight or an additive of some sort?

I can't afford to swap out all the oil again, so soon.

Thanks.

[slider2828]

Try additives, I mean it preserves the life of your tranny, but its not a miracle worker that fixes tranny's..... All you can try is maybe just some Lucas Additives or something.... How are you shifting, lightened flywheel, lightened shaft hi rev shifting or just regular shifting its grinding....?

[nismoskyz]

Hmm, I've read good and bad things about Lucas Additives (even in this thread alone) so I'm not sure...

Hah, I wish I had lightened flywheel and shaft. No, I'm shifting on stock setup, just with a counter-weighted shift knob.

I know the trans is old and has had its share of wear and tear, but when I first start driving and the trans is cold (I'd say about 50-70 deg F or so), It shifts like butter in every gear, including 3rd, of course. That's the only thing that's giving me hope that my 3rd gear grind can be remedied somehow.

It just seems like it could use something thicker, although I wouldn't want to use something too thick...

[slider2828]

Yeah anything thicker would move you to sever oil like 90-140 Sever gear oil which is sold. I dunno what can help you, but it ain't going to fix all your grinding issues inherent to tranny issues.

No...nothing you can do, pretty much, all you can do is rebuild the tranny. I'm at that point, tried running thicker oil, it kinda helped for a bit...3 weeks later, im back to the same point. Its getting so bad that i have to double clutch to get into 3rd without it grinding. Ill probably toss in my spare tranny and have the one in the car rebuilt.

[nismoskyz]

Its getting so bad that i have to double clutch to get into 3rd without it grinding.

I have to do the same, only when I'm on the throttle and shifting quick though. In normal cruising, if I shift from 2nd just right, sort of slowly, then strong into 3rd, I can get it in smoothly most of the time. But just shifting with a 'normal' force into 3rd will almost always cause it to grind.

What kind of thicker oil did you use?

Does your trans also shift fine in all gears when its cold?

[nismoskyz]

"75W-90" means the viscosity is 75 when its cold and 90 when its hot, right?

So if my trans is shifting better when its cold than when its warm and since 90 is a thicker weight than 75, wouldn't that imply that I need a thinner weight oil? Something closer to 75?
That doesn't make sense though, I would think something thicker would be necessary.

Someone care to explain?

[slider2828]

Yes you are correct 75W-90 for heat, BUT... 90 is usually when it gets extremely heated... It doesn't vary too much.... Any thinner oil might not protect as well and cause further damage. But then again I heard people putting 30W motor oil in SR tranny's no problem.... Oh wellz...

[nismoskyz]

hmm, idk, i just want my trans to shift smooth short of rebuilding/replacing the thing!

[ro240sx]

I finally changed my tranny oil with redline mt90 and its great. It got rid of a small 2nd gear grind and its make shifts smoother.

[fliprayzin240sx]

I had 75-90 oil in the tranny, poured some out and added a quart and a half of 75-140 to thicken it up. It helped a bit but not much, it still grinded and felt notchy as fuck trying to get into 3rd.

hmm yeah thats pretty similar to how mine is. It's not too bad though, and still feels better than the RP I had before.

I'm thinking about mixing in a quart or two of severe gear 75-140.

When you say "notchy" what do you mean? Like grinding, or the oil was too thick?

[rsibley22]

after running amsoil in my sr it got rid off all the noisy lifters will always buy amsoil from now on super happy cant wait to try the trans oil

[fliprayzin240sx]

Well I decided to pour out all the Royal Purple Oil and found some regular Quaker State oil, surprise surprise, tranny runs better. But its too late, I got hella shavings from running Royal Purple. SO my advice to everybody....DONT RUN ROYAL PURPLE TRANNY OIL!!!

Cliff Notes:
Got my car back from getting engine rebuild
Didnt know what tranny oil was in it so I swapped it out for RP 75/90s
Couple of days later 3rd gear starts grinding
Noticed that it runs better when tranny is still cold
Figured thicker oil might help so poured out half of the RP 75/90 for some 75/140s
Didnt make much difference
Poured out the Royal Purple Oil out
Swapped in regular gear oil and runs fucking better

[HYPNOTIK]

Ray, I'm running the Quaker State bullshit from the gas station right now and it seems really shitty when it's cold. Anytime I let it sit for more than 10-20 minutes and get back in it it will grind 2nd every time no matter how slow I shift. I was considering swapping to a RP 75w90/140 mix but it seems that hasn't helped you either. Have you found anything else on island thats worth a shit?

[nismoskyz]

^AMSOIL 75w90 is pretty good and, although it didnt solve my 3rd-grinding entirely, is still a huge step up from the 75w90 RP I was using. I'm thinking if I try a 75w90/140 mix of AMSOIL, it might do wonders...

[slider2828]

Hahha maybe..... I was thinking that too. Severe gear oil + Tranmission oil... It sounds like a good experiment..

[nismoskyz]

exactly :)

hopefully it wont break anything. i figure i might give amsoil a call and see if they have any input on mixing the oils.

[slider2828]

Just in case you missed it, I had it in my tranny ahahah and removed it and put the transmission transaxle oil in it. I am sure I didn't get all of that shit out, so far not a problem. But have like 1 qt of it, I don't think its going to mess with anything hahah.

[gsxr141]

i used a mix of 2 qts regular redline fluid and 1qt of redline shockproof. seems ok, but i still hear the synchros sometimes when i shift into 2nd.

[98s14inaz]

yeah i used redline mt-90. i'm honestly not happy with it right now...

I had the same experience, I tried redline MTL and I was much happier.

[slider2828]

Here you guys go to confirm what everyone has said....

http://www.synthetic-oil-tech.com/Gear%20Lube%20White%20Paper.pdf

This was an independent test of gear oils, of course this was not the test of the GL-5 Sever Gear oil, but I have ran it I with 3 full course track dayz and it worked fine.... But no surprise Amsoil came out on top. Also the Amsoils Sever Gear oil is GL-5 rated, but as seen in the materials test, it exceeded GL-4 standards with great protection for copper and stuff. Royal Purple straight FAILED!

O and I read on Amsoils site, you can mix the severe gear oils with other oils. So I am going to try and mix 75-140 Sever Gear oil .75 qts in there.... So a total 1/3 Sever Gear oil 2/3 Transaxle oil.... I think this might be the best result.

Honestly Casey...I have no fucking clue at this point. AAFES decided to run nothing but RP shit. Last time I went to FHS, they had some AMSOIL stuff, but they didnt have tranny oil, they only had gear lube (didnt get it cuz I thought its only for diffs 80-90W). At this point that would be better than anything else we can get our hands on.

I ordered some oil from AMSOIL but shit, been over a month and still nothing. Im thinking it got pinched and got sent back by APO for having HAZMAT or some shit like that.

[Bigsyke]

Ive been about 3k miles on the amsoil GL-5 75w90 gear oil (FGRQT-EA) Fully synthetic gear lube, (not the MTG which is GL4).

Still no grinding, its good stuff. Im ordering the MTG now.

AMSOIL SEVERE GEAR® (75W-110) provides superior performance and replaces competitors’ 75W-110, 75W- 90 and 80W-90 gear oils. It delivers better viscosity protection than SEVERE GEAR 75W-90 and better fuel efficiency than SEVERE GEAR 75W-140.

AMSOIL SEVERE GEAR® is compatible with conventional and synthetic gear oils. Mixing AMSOIL gear oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives, other than those specified by AMSOIL, are not recommended for use with AMSOIL gear oils.

Would AMSOIL's 80-90W GEAR OIL work for tranny? Then again who cares at this point since Im running Quaker State Gear Oil, again...cant find Tranny oil out here other than RP. If I try to get it off base, Im lookin at $25 per qt of regular crap. Even then still cant find GL4, theyre all GL5s.

[kevmeistah21]

soo i just bought mt-90 and put it in and on cold starts i can't put it into gear.. what could this be?

[slider2828]

Nothing, MT90 Sucks..... THat is why. Cold grinding is part of MT90, why you ask cause I tried it and that is what happened. Its junk.... Wait till the car is warmed up I bet you can put it into gear then.

I tried it Amsoil 80-90, worked great. Not much difference than the transaxle in my test. Can you try a 80-90 with a 80-140 75%/25% mix? I just wanna see if that helps. But I tried exactly 80-90 worked great.

Cant, all we got out here is that...Amsoil 80-90 Gear Lube. Next option thats not RP is Redline Shockproof which FUCK NO I wont run that shit either.

Well I drained it last night and toss in 3 qt of Amsoil GL and it shifts better than Quaker State for sure, even got rid of the notchy feel on reverse. Imma go test it out this weekend, got an all day HPDE. I just gotta adjust my clutch pedal down. Seems to be engaging way higher than it used to.

Also, anybody got any suggestion why my clutch pedal would feel stiffer when its hot?

[Bigsyke]

dropped in the mtg gl-4 amsoil. Shits amazing. 3k+ cruising is much smoother.

[ryan hagen]

i always use 1.5 redline mt-90 and 1 of shock proof light or heavy, depending what i have laying around and i havnt had problems in years

i picked up some motul GL-4 when i was at a race shop though. that im going to try out next.

probally try the amsoil in my daily driver that i test all my random trans in.

Oh wellz 80-90 it IS!!!

[Bigsyke]

Oh wellz 80-90 it IS!!!
The 80w90 wont have the antifoaming properties the MTG will have. I suggest your order 3 bottles of MTG on amsoil.com

The difference between the amsoil 75w90 gl-5 gear oil and the amsoil 75w90 transaxle MTG gl-4 oil is amazing. I used to have to shift into 1st before going into reverse. Problem solved

[slider2828]

O antifoaming properties? what is that?

[Bigsyke]

Reading around thats what ive found out on BITOG, you want the MTG if your going to be using the oil for an extended ammount of time.

Well I contacted AMSOIL Technical about it and this is the word from them:

"Nissan recommends only GL-4 lube. If the GL-5 AMSOIL 80W90 is used there may be a concern if lube temps. exceed about 275 F. S it depends on where you are and what kind of use the car is given. "

That pretty much mean FUCK YOU AAFES for not carrying GL-4 oil and all you got are crap GL-5 oil that likes to eat SR trannies!!!:rl:

[Bigsyke]

No question about it, when I drained the GL5 that shit looked like swamp water.

[nismo tuned s14]

I just put in some AMSOIL M/T 75W-90 oil in my transmission. Before, it had a slight grind going into third. That no longer happens, and it's noticeably smoother all around.

[Bigsyke]

^^^was it the MTG transaxle?

[JDMSTYLE]

sounds like ill be getting amsoil for my next trans fluid change.

[Om1kron]

does anyone know where I can get a bottle of the gl-4 transmission fluid locally in so cal. I only need one bottle and the closest distributor i know of is in vegas.

[ILoveMyRHS13]

Good to know. I bought AMSOil for my 5 speed swap. :)

[94_240sx]

This is it, right? I'll definitely use this for my next transmission oil change.

https://www.amsoil.com/StoreFront/images/fgr_350pxh.jpg

[Bigsyke]

^^^nope, thats the GL5

[fliprayzin240sx]

Well I went ahead and run GearLube on my shit, survived a track event with no detrimental shit, shifts fine, never grinded (well 1st did but its notorious for SR/KA trannies not wanting to go into 1st when your doing over 15mph without rev matching the shit out of it).

Anyways, I got a more indepth explanation why the GL-5 sucks for our trannies. Once gear lube temp goes over 275, something in the lube becomes a corrosive agent for brass synchros, thats why they dont recommend their GL-5 gear lube into the tranny. But if you dont put heavy load on it, itll never get that hot and its good enough.

[nismoskyz]

uh i think i have like 1/3 of a bottle sitting in my garage if you want it

[Om1kron]

I'm pretty sure I'll need a bit more than that.

[jiggs]

Anybody tried vavoline full synthetic? Its the only trans, diff oil available in our area..

[SilviaSR20DET]

i still think penzoil syncromesh worked wonders for the ka trannies. Mine never misses gear or grinds like it used to when using mobil 1.

holy crap i was gonna buy this $13 each like 4 of um for my trans and diff, good thing i never if you guys are saying its junk...

[slider2828]

There is a picture of the bottle a few webpages back. It says literally, Transmission/Transaxle Oil on it.... You can't mix it up....

For Flipz - I ran 3 trackdays on it and no problem. I am coming to Japan in Sept, I wonder if I can bring some over for you. LMK

[clark]

just bought 3 quarts of the GL-4 75w-90 for my SR tranny. i will post my observations once i change the oil.

[HasteBryant]

BG oil 75W-140

Used for the last 3 years on same trans. Daily/Track No grinds.

http://www.turbomatrix.co.uk/images/t_19176_S.jpg

[0wn3r]

O and I read on Amsoils site, you can mix the severe gear oils with other oils. So I am going to try and mix 75-140 Sever Gear oil .75 qts in there.... So a total 1/3 Sever Gear oil 2/3 Transaxle oil.... I think this might be the best result.

Did you end up doing this; mixing in a little of the SVG with the MTG? Curious how it's working out

[slider2828]

Not really.... Haven't mixed yet.... I mean I drained the MTG and put SVG in it, so theres got to be like a 1/2 quart left in it, but nope... nothing yet... Its expensive and a pain in the ass to do tranny oil without a lift.... lol

[xpertsnowcarver]

Been using lucas 80w-90 for the last three years. Works great. Going to try something else next year :)

[garagelu]

I just went to the Amsoil 75w-90 MTG in my trans and went ahead and changed out my diff fluid to severe gear 75w-90. I know oem specifies 80w-90 in the diff but if you look at the description for SG 75w-90, its says it is a replacement for competitors 75w-90 and 80w-90.

And not sure if anyone sees this on amsoil website but on their main page on the top right is a product lookup guide. It will tell you which fluids are specified for your car.

Im going to be switching to amsoil engine oil and filter pretty soon. My dealer can get it for about 6.30 for the 10w-40. The filter is what gets you and that is like 10-12 dollars iirc. But it lasts for up to 25,000 miles and the oil lasts for 7,500/6 months. So I am pretty sure that is around the same price as mobil one or something equivalent when you look at everything as a whole.

I would definately recommend amsoil to everyone. The trans feels so much smoother switching from mt-90 redline. I am expecting the engine to be a little quieter and smoother with amsoil engine oil.....lets hope.

[slider2828]

Hey garagelu.... I tried the engine oil... for the price... I would rather much go with Redline actually... Redline makes really good engine oil.... But really 6.30 NOW WAY!!! That is so cheap... But go with 10-30 not 10-40 seriously...

[cumbewong]

so what's better or preferred? LUCAS or AMSOIL? about two days ago my trannys been grinding like shit. I need some new oil :P

[slider2828]

Definitely AMSOIL....

[cumbewong]

alright thanks :)

[slider2828]

Read the WHOLE thread. Make sure you get the transmission and transaxle oil NOT the Severe Gear Oil....

[mothon]

Yes, amsoil amsoil amsoil

[Spitfire8o5]

This threads badd!!! 7 pages were all funny and interesting.. Barely got my 240 couple of days ago and the bastard just did a tranny flush with royal purple and I feel like telling him that he's an idiot haha.. But if all gears are smooth with royal purbo just a slight grind in 2nd..

AMsOil 75w90 seems to be what everyone is having orgasms over and seems to be the favorite or many.. So I'll give that a go soon.. Hopefully this upcoming week, and the 80w90 gear oil would be best for the diff right? Because that's whati have stuck in my head haha.. Someone please correct me if I'm wrong before I make another mistake

[JKL1031]

where can i get the amsoil?

[JKL1031]

Could I use 75w-110 amsoil? Its all one dealer has without goin to different dealers all over the place.

[JKL1031]

anyone??? 10characters..

[Bigsyke]

No you need to use the GL4 75w90 from the amsoils site, I had to order mine.

[JKL1031]

i might grab two and then mix with some lucas?

[Slikk Logic]

eh im on Pennzoil syncromesh. i adopted it from my turbo civic and that trans has been holding up good for years no grinds lol. works great in the ka trans too. never a shifting problem

[dongoesby]

for those who care about your tranny, go read the thread. All you need are basically in the first 2 pages.

I just done the amsoil gear lube. ABSOLUTELY loving it!!! 2.5qt bottles, you are set. Nothing else!!

THANKS KEN!!!! Your S13 rules! :)

We take 75w. Synchromesh is like a 10w. Horrible Idea

[VQdriver]

Sorry to bring back an old thread. I have MT-90 in my SR trans and and it shifts great.

I have a few bottles of the new Redline MT-85 which is GL-4 rated but with a viscosity of 75W-85. This is required for the Z33 which is very sensitive to viscosity. I would like to try this on my S13. I will let everyone know how it is.

Can someone with the service manual please tell me the exact oem viscosity specification for the S13 SR transmission?

I want to make sure I'm not using too light of an oil however I did notice someone using Redline MTL which is even thinner...so I guess I should be ok.

[KA240SX808]

Same 75w90 the KA's take...

[VQdriver]

Same 75w90 the KA's take...
I figured that. Thanks. Perhaps what I'll do is use the 1.2 leftover quarts of MT-90 I have and then top it off with the MT-85. :cj:

[unreal-]

Another +1 for Amsoil. I've been usin it since i got the car and i LOVE it. 1-2 grinds are only noticeable if the trans is DEAD cold (40* ambient temps and lower) and you try to race shift it :D. But i'd chalk that up to my old trans/synchros. Once its warmed up though, it shifts like butter. 1st is easy to get in to, and grinds are non-existent. Although it is terribly expensive (13.60/qt) it is well worth the price.

[slider2828]

Well seriuously though if you look at it its not that bad. Unless you race, I mean you rarely change tranny oil in general. I mean maybe 20k miles for normal wear. And at 2.5 quarts its about $40 bux..... You spend way more on that on oil for an SR motor....

Breaking it down, Amsoil is cheap and good stuff..... Redline, I never use period... their shockproof stuff is crap.... MT90 isn't much different.... oil wellz....

AMSOIL FTW.....

[CrimsonRockett]

Ran Motul on my brother's S14. Shifting went from bad to worse. As soon as the gear oil warms up, shifting is HORRIBLE. It won't even go into gears without force. Not grinding any gears. It's just as if they're completely blocked off.

After coming to a complete stop and trying to put it into first, it won't budge at all. Have to try forcing it into another gear to line them up, then into first.

Transmission rebuild needed or try switching over to Amsoil?

Clutch grabs fine. New Nismo trans mount, driftfreaq motor mounts, B&M V2 shifter, all seals good, driveshaft carrier bearing is good, subframe bushings are good and diff bushings are good. No real play there.

Just wondering if I should try out Amsoil first before dropping the trans and sending it off to get rebuilt.

[Bigsyke]

Ive noticed amsoil doesnt use any moly in their oil, I've been searching around for a soluble moly add that become acidic after a period of time. I would assume molybdenum would be a perfect ingredient in the transmission since it seems to etch into the metal surfaces and create a barrier similar to zink and phos and be a great anti-friction/wear package, similar effect to lubegard in an automatic transmission.

My transmission was similar. Amsoil helped a tad bit, however my issue was bleeding the slave and the clutch pedal. I've used 3 people to bleed the clutch, a brake vac pump, but the only way I could truly bleed it was a gravity bleed, where I cracked the bleeder open and let it drip for a solid 30 minutes while refilling. After that I hardly grind. I dont think the fluid makes enough difference to magically open a shift gate, I would say it could also be something with the spring and ball tensioner below the shifter if hes not grinding, that should stabilize the fork.

There are two 75w-90 amsoil fluids right? One says gear lube, the other says man transaxle n something lube. Both are fine but not the severe gear correct? Also I can fill the trans from the top?

I was also told adding some pennzoil synchromesh would be help or be fine at least? I've only contacted two dealers at one bottle each that have this stuff ffor sure. If the nos have it against the synchromesh, than how about someThing normal from autozone.

I went to the dealer, and all he had was was severe gear. I see you all say thats its bad for the copper. But really, Im home on thanksgiving break, and i go to school 128miles away. I see on their site it says it can be used in GL-4 applications. It also has a copper wear rating that im not sure is good or bad.

Recommended for use in differentials, manual transmissions and other gear applications requiring any of the following specifications: API GL-5, MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037), Mack GO-J, or the differential (hypoid) gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler.

Post #215 is the correct Amsoil application. Severe gear is only for the rear diff I believe. It might not be slippery enough for the transmission but I'm taking a wild guess. If you're in a pinch why not go to a Nissan or Infiniti dealer (call for best price) and pick up 3qts. Their stuff works great in my G35. I recently switched to MT-85 and that stuff is awesome for later Nissan models. I'm actually doing my fluid change on my S13 now. I'm taking a break. I'm using my leftover qt of Redline MT-90 and topping off with a couple qts MT-85. I'll let everyone know how it performs.

We take 75w. Synchromesh is like a 10w. Horrible Idea

idk what weight is is acctually lol its on shelf at autozone. i think its replica of the corvette fluid

I wouldnt get anything from the dealer cause My synchros are on the fritz already. they keep going in and out, but i believe its once the fluid is not warm, but hot. I drove the drive from school, and 3rd was grinding again. next day(today) i drive around with no problems again.

I wont be mixing any synchromesh, he ordered me three of the right thing. i see there's a amsoil synchromesh. Any info on that??

Quick update. I drove my car recently. I'm running new Redline MT-85 in the trans and Motul 90PA in the diff which is Kaaz 2way equipped. The transmission is shifting nice and smooth and the LSD is working just fine.

Hear good things about GM synchromesh. IT's the same as penzoil. GM is 3-5 times more expensive but has same parts number. GM buys from Penzoil brand the name and sell it as their own. My second gear synchro grinds, so I'll buy 3 litters and it should drastically reduce the grinds, I hope.

ok flamesuit on.. what would you guys recommend for an r33 trans? Ran MT-90, and autozone valvoline for 5.99 a quart. Didnt notice a difference. About to do a tranny flush, recomedations?

[VQdriver]

LOL

I went back and read my first posts in this thread, and I STILL HAVEN'T CHANGED MY TRANS OIL hahahahahahahaha

Still running the MT-90 I think hahahahaha

I looked at the Amsoil trans oil the other night too, I was like "man I really need to change my trans oil", and yet I still haven't hahaha

If you think about it the transmission oil doesn't have to be changed often at all. At least you've got the good stuff in there.

Singlecam: if the R33 requires a GL4 transmission oil I would recommend Nissan MTF 75W-85, Redline MT-90 or MT-85, Amsoil 75W-90 GL4. GL4 is tough to find, but at least you can get Nissan MTF locally.

sound like the r33 trans is in good condition.

i like pennzoil synchromesh. it has the consistency of water, but it's given me better shifting performance than any other off the shelf dino oil. in fact, it got rid of my 2nd gear grind in my old coupe. i would consider redline or amsoil, but i don't want to shell out $50 for gear oil every 10K miles on a bone stock NA KA.

Why are you changing your Transmission Oil every 10K?

[SoSideways]

Why are you changing your Transmission Oil every 10K?

I believe he's the same guy that only runs Advan Neova AD07s or now AD08s on the street, because he can, and because he literally wants nothing but the best for his car, even for mundane stuff like going to the grocery store.

[Bigsyke]

If he wants nothing but the best for his car why is he complaining about $50 every 10k miles? The transmission fluid doesnt break down, its the metal shavings and the oxidation that MAY occur over 50k miles. On a stock KA trans im sure 100k miles is safer than running syncromesh for 100 miles.

[singlecamslam]

Does he change his engine oil every weekend? You can buy a ka tranny with every 2 oil changer he does. I dont know, personal preference i guess, to each his own.

[SoSideways]

I dunno, but I'm pretty sure KA and SR trans are pretty much the same, and I've had the same MT-90 in my trans for the last 3 years, even though a whole year of it was just straight sitting there in the trans since the car was on jack stands for a whole year.

It does suck in the cold though.

Amsoil will go in whenever I get a chance to meet all these requirements:

a) actually have the motivation to work on the car
b) it's not 40 degrees in the garage
c) have the motivation to work on the car
d) not playing COD: Black Ops on the 360
e) have the motivation to work on the car

So as you can see, unless the planets and the stars align just right, you guys will probably never see me post in here saying I changed my trans oil out. Maybe on 12/21/12 I might.

[soreballz]

My trans hates syncromesh. So much, in fact, that it has become retardedly notchy on every upshift, and the input shaft bearing is giving up on me. The noises that it's making now are painful to listen to. The trans will be replaced within the next month or so (provided that it doesn't blow up before I source another), and the new one will ONLY see Amsoil.

[singlecamslam]

mannnn, my ka tranny started grinding on fast shifts today. Gonna try different oil see if it works. Gay.

[JKL1031]

I left my shop with 3 quarts and yet their asking for 2 more???

[NickIsAZero]

I'll be trying the Amsoil 75w-90 gl4 soon, I'm actually ordering it right now... $50.67 shipped

[S14DB]

Are they filling through the shifter or the fill port on the side of the transmission?

[JKL1031]

I talked to hum hebfilled thru the side. No big improvement as of yet. My shifter is still crunchy like a scrunchy. it was going right into first from a stop w/o going into 2nd or third first when it was cold. My only problem was thrid scratching once the fluid was not warm, but hot. $72 dayum dollars.

[roadster6909]

What kind of oil should i use for sr20det first start up after rebuild?
What kind of tranny oil would be the best? How much of each?

BRO.

This entire thread was talking about what trans oil to use.

BRO.

Go back and read the first 8 pages before you ask that question again, or try to flame me with some dumbass come back.

[roadster6909]

Not necessarily a come back, but okay..
I was at school, read the first few pages that stated what brand, or what kind but not mentioning if it's for an sr20det, or a ka, or an airplane.
Or it was saying what kind of oil for the engine, so sorry.. i didn't really want to continue looking so i just asked, stop being mean.. thanks

No way, unless he is swyping shit from you the tranny is ONLY 2.5 qts.... It takes a little while the performance of the oil really comes in when its warm... Also if it is 30 degrees outside, give your car a couple of minutes to warm up... But once the oil is warm to hot, it will help....

Now like I have always said, its not a miracle worker, but it will reduce wear and it will help but if your synchros are gone, its gone....

KA/SR/VG all use basically the same trans and the same fluid.

Also, this isn't an engine oil thread. Get outta here with those off topic shenanigans.

[platypus_s14]

just wanted to contribute a few points. there are gl-4 and gl-5 rated fluids. motul's gear 300 is one of those. i also do believe amsoil's severe gear is gl-4/gl-5 rated. so it's safe for nissan's gl-4 rated trannys and gl-5 rated diffs.

also a grinding tranny can get better by changing the fluid but if it's really thrashed...it doesn't matter what kind of magical baby tear based fluid collected by the fairies of amador you use. it can't reverse the damage.

[pink godzila]

Wakos... 90% of race car in Japan uses Wakos oil.

Ill try Amsoil.. any retail carry them?

As far they only can be order from online.

[JKL1031]

Yes mines must be o the point of no return, but I can get into first a little easier.

Not a reason for me to chose an oil. Race series in the US use crap I would never use.

Check their website, they have a dealer finder. You can also become a preferred customer and get a discount. The margins really only pay for shipping. Sales Tax would be as much.
