Just ordered 2 bottles of Redline 75/90w

[SilvSpec]

I just ordered some redline oil 75/90w:

First, how much do i need to use b/c some people told me that if i use too much or too little i can ruin my transmission.

Second, how do i exactly change the oil, could i do it myself? If so, how could I?

See my 2nd and 3rd gear always scratches when i nearly reach redline and changing the gears fast(in other words dogging it out or racing it) and 1/4 of the time it grinds when i try to downshift to 2nd at 35mph+.  So im guessing that the redline oil should help and smooth out my shifting, ( i hope it does)

Thanks

Yes, too little fluid can ruin your tranny.  However in our manual, you can't put in to much.  You know its full when it starts pouring out of the fill hole.  I'm pretty bussy so I can't write up a full how-to right now but do a search, you'll surely find something on how to change it.  You need 3 bottles BTW, tranny takes ~2.75qt.

[240 2NR]

S13 manual trans requires 2.4 liters, and the diff requires 1.3 liters.  They both use the same fluid so if you need more, order enough to refill the diff as well.

The procedure is pretty much the same for both.

-Jack up car (at all four corner and on on jack stands so it's level is even better)

-Using a 1/2" socket wrench, remove the drain plug (you'll probably want to clean it first and I used an extension rather than gunk up the more expensive torque wrench)

-Allow the fluid to drain and clean off the plug (it has a magnet so all those funny particles are metal shavings)

-Screw drain plug back in and remove filler plug (driver's side)

-Using a suction gun (sort of like a grease gun that sucks up grease and then pumps it out) draw up your trans fluid and begin filling the trans (or diff)

-The case is full when the level is just below the edge of the filler hole.  When it begins overflowing it's actually over filled.  That's not a probelm since the case will vent off the excess, but it will get the underside of the car covered in oil and will puddle in your garage.

-Put filler plug back in and go drive your newly lubed ride.

The plugs should be torqued to 18-25 ft-lbs when reinstalled.

Isn't the 75/90w the diff. fluid? IIRC, MT-90 is the correct tranny fluid. Could be wrong tho... &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>

240 2nr said everything nicely.....

couple of pointers though

1) u can fill the new oil by taking out the shifter and using a long funnel and imagine to use 2.75 liters......thats what i did.....since it be harder to put oil in thru filler plug.....mine is 95 s14 with s14 sr....

2) I used mtl 90.....there is another called mt 90....basically same thing except one is a little heavier weight or something like that....

3) keep goggles on your eyes

4) keep a cloth nearby when under the car....

5) before doing this, go drive the car around the block so that the oil is luke warm and easy to drain.....

Hope that helps....

SilvSpec,

I would highly recommend that you do NOT use any Redline fluid in your vehicle. &nbsp;Redline tranny fluid contains phexophedemine molecules which slowly eat up your syncros over time. &nbsp;Not only that, but if they reach a certain temperature, they have a tendency to cause detonation inside the transmission housing.

My friend Jimmy put some Redline 75-90W in his tranny over a year ago. &nbsp;All was going well for a few hours until we drove up the mountains to battle a Starlet. While we were taking the downhill, I heard my friend downshift from 4th to 3rd. &nbsp;What happened afterwards was the most horrifying image I had ever witnessed in my entire life. His tranny blew up, literally. It caught on fire and fell off his car. He lost control and drove off the mountain pass &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/nervous.gif" border="0" valign="absmiddle" alt=':nervous:'> . We found his body in the car, slumped over the steering wheel.... with the shift knob sticking out of his throat. *sob*

[anthony240]

wow, sorry to hear that <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('> . but that doesn't happen to everyone. I've used Redline ever since I got my 5speed tranny, and it's been fine, no, it's been great. i live right beside a mountain pass and I go through there at least once a week. one thing to remember, the tranny requires 75w90 GL4, also called MT90, this is what I'm using now. when I first filled it I used 75w90 GL5, Redline marks this 75w90 on the bottle. this is the wrong fluid, it stunk up my engine bay and you would hear the fluid gurgling, and the tranny would be hot. if you're going to use Redline, go for MT90. there are other good tranny fluids out there, like Mobil 1. Just remember that they are Synthetic and you can't mix it with organic.

[SilvSpec]

Alright, well im really confused right now <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/crazy.gif" border="0" valign="absmiddle" alt=':crazy:'> . I need to know how many bottles and what kind of transmission fluid do I exactly need. &nbsp;I ordered my redline from this site Lighting Motorsports (http://www.lightningmotorsports.com/redline.htm). &nbsp;I ordered 4 bottles of 75W90 GEAR OIL, is this the right one or not? another thing is that I'm going to get a mechanic to do this for me because I don't want to fool around with my transmission and messing it up.

[Hurricane240]

Cool Kat you are a really bad lier. I don't care if you have nitro in your transmission it won't blow up catch on fire and fall off the car. And at the begining of your story you were in the car, but by the end only your buddie drive off the cliff and died but you were fine because you told us this delightfull story. So sorry bud nice try.

[anthony240]

SilvSpec, that is the WRONG fluid, it specifies for differentials. The right one is MT90.

Hurricane, I don't know what kind of shit you're on, but where in his post did he say he was in the car? I got the impression that he was driving behind his friend, and he heard him downshift, and saw the tranny fall. It's completely possible, the fluid might have been very low and when he downshifted, the gears probably grinded and caused a spark and set the tranny fluid on fire. and the incredible heat probably melted the tranny off the engine. its just one of those freak accidents. auto trannies actually DO fall when people do neutral drops often. so who are you to accuse this guy of lying when you can't even prove it? dumbass...if he's a liar then I'm a dope for believing him.

[SilvSpec]

Thanks for all the info guys, I guess I'm going to ship my 4 bottles back to where I got it from and exchange it for the MT90. &nbsp;Hopefully everything will work out right.

Thanks

Hi, I was actually gonna change my trans fluid too. I pretty much know what to do but does anyone have any pictures of the drain and filler holes? Pics would be really nice.

Thanks fellas

I don't know enough about chemistry, physics, or transmissions to make a call on whether or not this is true...but since you called him out, please provide us with some facts/proof for your claims.

Also, if you read his story you would see that at no point was he in the vehicle. "we drove" doesn't mean in the same vehicle incase this is the part the threw you off.

I find it hard to believe however that the tranny oil was the cause for that accident. Since it is oil used by many race car drivers.

I'm running mobile 1 synthetic 75w-90 and I've run mt-90 (which IS synthetic 75w-90 oil btw) and I felt no difference. The price is about the same but the mobile 1 can be found at your local autozone. Also, bbp (owner/driver of s14 race car) recommends mobile over redline for its protection of syncros.

You'll need three bottles of mt90 for your tranny and Two bottles of 75w-90 gear oil for your differential. Don't bother sending the stuff back, just use it for your differential and buy some more oil for your tranny...so what if you have a bottle of gear oil left over, you'll use it later. I'll do my best to get a full writeup start to finish with pics etc tomorrow...I've been wanting to do it for months anyway.

Edit: sorry 2, 1qt bottles for differential, not three.

[wpayne]

Thanks DCS. You are good <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'>

[DSC]

After a bit of research, I can't find that phexophedemine molecules exist at all. Maybe a misspelling? Maybe a troll? Maybe someone can clarify that for me.

EDIT: Alright guys, I just got the engine oil write up finished, tranny and differential should be done tonight. Let me know if this is easy to follow so I can make changes and clarify as needed.

Enjoy <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

Much Appreciation! Thanks DSC!

[azdaren]

DCS,

Just used your pics/instructions to do the tranny/dif fluid change. Thanks for the info and especially the pics.

Daren

[Fibercus]

Many thanks, changing out my fluid today and that howto is awesome.

[Joe_M]

So let me get this straight.......

3 qts. of MT(L)-90/Mobil 1 75w-90 for the transmission
2 qts. of 75w-90 gear oil for the differential

Summit Racing sells the stuff for 7.95 a bottle and has free shipping and you can get it in 2 days. Here are the part numbers....

RED-50304 90W manual trans. fluid ..... 7.95
RED-57904 75w90 Gear oil for LSD ..... 7.95
RED-58304 75w90NS gear oil for non-LSD.... 7.95

So I guess this stuff is worth getting? My synchros are kinda crappy right now, will that help it out somewhat?

Joe

[logo20]

shouldn't the transmission and differential fluid be the same? why use 75w-90 gear oil for the differential? I thought the right fluid for the differential would be the same redline mt-90.

[drift into a curb]

The transmission and differential fluid are different because the diff fluid has a additive for the limited slip. It may have the same weight, but it was designed for different uses.

[MorganS13]

just a FYI... u can run MT90, MTL, or the shockproof gear oils in your tranny with no problems. i've been running lightweight shockproof for a while now and have no complaints. helped hide my synchro problem quite a bit

[logo20]

anybody else know why 75w-90gear oil is better than mt-90 in the differential?
I'll probably just use mt-90.

[drift into a curb]

It's not that it is better. The 75w-90 gear oil was made to use for differentials. The MT90 is for transmissions.

[logo20]

let me ask it this way, would it be ok if I used mt-90 in the differential instead of 75w-90 gear oil? I'm assuming yes, but i'm not sure.

[logo20]

I got this from my myoilshop.com
"MTL is not designed for use in rear-wheel drive differentials. Those generally require a GL-5 lubricant such as Red Line 75W90."
our differential use GL-5? I didn't know that.

[Got Sileighty?]

wow that SEARCH button does work. i was just looking for a faq on changing tranny fluid. thanks DSC. but now i have another question. is everything exactly the same for a s13?? (like the location of the plugs, etc.)

[Eastcoast240]

75W90 for VLSD and MT 90 for gearbox.........any one know for sure?

[drift into a curb]

"Red Line MTL is classified as a 75W/80W gear lubricant satisfying the API Service requirements of GL-3 and GL-4. Satisfies manual transmissions and transaxles requiring motor oils or GL-1, GL-3, or GL-4 gear oils." myoilshop.com

logo20, you answered your own question :P Yes, our rear differentials require GL-5. Eastcoast, read over the thread.

[logo20]

thanks drift into a curb, I just wanted to make sure. :)
