installed: peak perf. tranny mounts and redline 75w250 tranny fluid. VIBRATION PROB.

[lv-180sx]

alright, i just installed a street version peak performance tranny mount, changed
my tranny oil to redline shockproof heavy (75w250) along with the fluid in my nismo 2-way diff.. first thing i notcied after i drove off is that everything is vibrating REALLY bad when im in gear at around 3k+ rpm.. is this normal? also, when im in neutral and when i rev to 3k + it vibrates really bad too... is it normal
for the car to vibrate? is it because the new fluid or the tranny mounts? also is redline shockproof safe to use in a nismo 2way? on the label it says for use with hard locking diffs. so is it ok?

[DJ_Sunrise]

dbl check the tranny mounts.. they'll always make things vibrate considerably more, but i heard it was only at idle.. well.. thats for the nismo units anyway.. arent the peaks stiffer? dbl check that they are installed properly.. otherwise id say they're gonna take some time to break in. everything else is straight, shockproof wont make things vibrate. pop ur hood, put ur hand on the engine and rev.. ull see if the engine is causing the vibration or not haha

thanks for the info..

i triple checked everything when i was done installing, and everything was ok. im thinking my tranny isnt getting enough lubrication due to such a heavy ass weight while being cold... also can someone confirm that its ok to run shockproof in a nismo 2-way? what weight would be better? because my diff is making a weird squeaking noise for a matter of a second after i rev up... not loud, just really faint though...

[lv-180sx]

nvm, the noise was something else not the diff. any suggestions??

[SimpleSexy180]

i thought we are suppose to used 75 90 for transmission?

[lv-180sx]

bump, any more tips?

[orion::S14]

Yes - Get the proper weight oil and put it in your trans.

It's hard to diganose a problem when you're using fluid that's WAY too thick...that me be the problem, it may be somethig else...but either way, once you get the right fluid in your trans, you can 1) rule that out, or 2) have no more issues.

Buy some MT90, drain the corn syrup that's in there right now, put in the MT90, see if the problem persists.

Then we can help more.

^^ agreed, mt90 for tranny, shockproof for differential

if this is stupid for me to run that heavy of a weight than why the hell is phase2motortrend selling this stuff? http://www.store.yahoo.com/phase2motorsports/rehedush.html


also, im not an idiot, i wouldnt just throw away $40 of fluid without doing research. according to this thread: http://www.zilvia.net/f/showthread.php?t=60620&highlight=redline+shockproof
redline shockproof heavy weight was the best bang for the buck... all im trying to figure is if it's normal for this to happen with stiffer tranny mounts, or this heavy of a weight fluid... im also just asking if its ok to run this fluid in my nismo 2 way lsd..

[asiangento]

peak tranny mounts are the shit. i've had mine for over a yr. it makes it vibrate a little more just because it's stiffer. so i dont know how much urs is vibrating, but mines not "something's wrong" vibrating.

when i ran redline in my tranny, it would grind gears when it's cold out, so i went back to 75w-90 (i think), which is stock weight. no vibrations when i had that in.

as far as i know, ur not suppose to run synthetic fluid in ur lsd. i use any non synthetic 80w-90 w/ ford friction modifier.

hope this helps.

[Pstl_pete]

I ran a 2:1 mix of Redline shockproof and MT90 and even then the thickness is too much. The transmission grinds when its cold and takes forever to warm up to proper viscocity and I have a worn tranny.

After talking to the folks over at Redline, they dont recommend you run heavy shockproof unless you are using the car occasionally (race,drift). The shockproof wears out quickly and is meant for transmission that are worn out and not daily drivers. Read the info on their website and it explains it in better detail.

I am going back to MT90 as it is the best stuff out there.

It says for heavy race use on their site. Don't try to blame Phase2 because you didn't know. Just cause they have it on their site doesn't mean you need it for your application. :squint:

as far as i know, synthetic fluid can, over time, eat synchros in the tranny

[tastyratz]

for what its worth i have solid eurethane engine mounts in my car now. vibration is hella all the way to 3k it is NOT just idle like everyone says so id imagine a stiff tranny mount could contribute to that. I run a tranny insert and that contributed/ giving the cabin some vibration as well. at idle my bolts and misc. things in the car vibrate like crazy, more so than when my sub pounds... I have a 200w infinity basslink. vibration is harsh but i dont care

[S14DB]

If you have the stock engine mounts the vibration is prolly from the engine rocking yet the tranny stays stiff. So, all the engine tq and vibration gets transferred to the tranny mount as the engine mounts slop about.

thanks for the info man.

as far as i know, you can use synthetic in Nismo/ Tomei LSD's but not in the Kaaz clutch type LSD's.



also, with your peak performance trans mount, it vibrates at around 3k right? i mean, not "something's broken" vibrating, just like you can feel it in your steering wheel and you hear your key chain shaking right?

[kandyflip445]

As long as it's GL-4 rated it will be fine. GL-5's can eat away at softer metals used in older trannies. It takes a long time though.

Tastyratz- Do you have any chassis braces? The only noise my car makes now is a squeak from where the front bumper bolts to the fender (a 10mm bolt/screw is missing) and right behind that dash. A couple braces might help. :) Unless you're hardcore! I'm too pansie to ride around like that. Noises make me angry. :rofl:


Isn't it funny that Kaaz makes Tomei LSD's too?

:duh: yes im sorry that was it, gl5 is what eats synchros over time

well... when i talked to the guys a kaaz, they told me not to run synthetic in clutch type lsd's. i might have heard wrong... i dont remember. i have a tomei 2 way.

when i first put the mount on, i dont remember it being to rough. just a lot more direct feeling. now my car is stripped and loud as hell, so i cant tell.

sorry i couldnt help further.

like was said earlier if you replace your trans mount with a stiffer one without replacing your engine mounts you will get vibration from your engine mounts. On the other hand different companies mounts behave differently.
We had a customer who had cusco engine mounts with a spl trans mount which is very similar to your peak performance trans mount and he had excessive dash vibration and shifter vibration. After switching to our Syko Performance Urethane engine mounts his dash vibration and shifter vibration disappeared.
Its up to you, I would suggest change your engine mounts. If you are wondering about our mounts check out the group buy section. Oh ya they ship out superfast priority mail :D

[fliprayzin240sx]

I kinda had this same issue. My tranny would vibrate so much at 90mph that it seems like my shifter will just fly out. At first I thought maybe I put my drive shaft back in the wrong way *didnt line it up properly so its unbalanced* changed my fluid it and it went away. Running Redline 75-90W now.
