ok well with how crappy the search function is on this forum i need to make another thread.

i am getting my trans rebuilt and everything will be new. so i want to start it off with the right fluid. im not interested in anything other then the 2 brands i just mentioned. so there is no need to recommend anything else to me.

the car is used for weekend drag racing and mainly highway fun. i only want info from guys who are making big numbers/fast track times and really beat the **** out of there car/trans. anyone else need not apply. hard core track guys are also welcome..all i want to know is what your using and how do you like it. also explain your trans setup/builder and miles you have been using one of the brand fluids i am interested in.

also what viscosity ''spell check'' are you using or model fluid should i say??

SHOP GUYS. please post up. im more interested in your guys input then anyone else.

NOTE... i know a dead cold trans with thick fluid does not shift well. i dont care about that as i never drive the car till its warmed up anyway. thanks to those who can help.

anyone??

HEavily abused cars we use Redline Shockproof Lightweight..

Light abuse and daily driven cars we use Amsoil MTG

I find the MTG does shift smoother, easier to warm up and lasts a while..

I have heard the same as well. I will be using MTG in the near future.

we have a series of track cars (NOT ONLY EVOS) that we have spnsored and are running AMSOIL.

AMSOIL MTG is a fully synthetic oil and it will not loose its film, it will not break down and it wil not let loose any polymers like other oils contain, however i guess when you are rebuilding your tranny once in a while you dont care about polymers because it will get cleanned up by the builder.

i will see if i can have one of the guys vouch in here, the car is a full road race car using AMSOIL MTG GL4

I've tried a lot of fluids and have yet to find one better than the Redline MT-90/MTL mix. Its all I ever recommend to people and everyone seems to like it. My car sees daily-driven abuse plus autocross.

amsoil ftw =]

How about SVG for abused like hell cars? Mine is showing a ton of metal in the gear oil using just MTG.

thanks mike. i think im going to go with the redline shockproof lightweight after talking with alex at dog box racing.

NO>>>> do not use any of the shockproof products. They are not designed for this type of use. MTL, MT90 only if you're going to use Redline.

ok why not?

Here is what Team Rip has to say about shockproof.

"it has been found that the heavy paraffin-like particles are quickly centrifuged out of the oil and build up inside the center diff housing and around the synchronizers and inside of the gearshafts. After several oil changes this build up may block oiling passages inside the gearshafts that lubricate the needle bearings and can reduce the overall effectiveness of the synchronizers, leading to poor shift quality. Therefore we do not suggest using Shockproof in the transmission unless the transmission is to be serviced often or a dog box."


I can also add that during a recent tranny rebuild I did for a friend using shockpoop. The oil passages were gunked up bad. Required a lot more clean up than an normal tranny rebuild. He switched over to Redline cocktail mix as we call it, and could not be happier with the tranny.

+1 amsoil mtg

I ran all Redline and just switched to AMSoil. It is hard to notice any difference in feel, but my initial impressions of the AMSoil transmission fluid is that it is marginally smoother than the Redline. I have heard similar warnings on using the lightweight shockproof in the tranny, though the heavy is what you want for the tcase and diff. I dont remember the price difference, but the AMSoil is by no means cheap (not saying the Redline is any better). Assuming the price is the same, I would try the AMSoil as it is touted all over this board as the best. In the future I will likely run Mobil 1 in the motor and AMSoil in the rest of the drivetrain to save some money on fluid changes ($75 vs. $100 per total swap) and the Mobil fluid is very good stuff too.

this is what we have explainned in many threads.
we are gald the rest are catching up and noticing the same thing.
