Tranny Fluid in your Evo

[evogsrviii]

What kind of trans fluid are you guys running in your Evos? I have heard mixed reviews on redline. Need to get this done soon.

[blewby u]

i'd like to know this too, i'm due soon

I've run Pensoil Syncromesh in mine for over 100k. It's great but I change it often. If you talk to TRE he'll recommend that you use the MR trans fluid in the 5 or 6 speed. I believe Shep recommends Redline

Consensus on EVOM is

-Redline MTL
-Amsoil MTG
-MR Diaqueen
-Pensoil/GM Syncomesh
-BG II

[evogsrviii]

yea, people seem to like the amsoil mtg.

[Metal4all6]

I use AMSOIL MTG in the tranny (and engine, dif, and transfer case). Awesome stuff!

[Got Insulin?]

Although, I have a DSM, I run EVO MR fluids and they work wonders for me.

I don't have an Evo, but the best stuff for my transmission would be the Redline. Others recommend the Amsoil, and yet others recommend GM Syncromesh.

Every fluid feels different, it's largely opinion on which is best. If you like how it feels now, replace with that same kind of fluid, if you don't, try something else.

Just make sure to stay within specs on the type of fluid. I don't know too much about specifics on Evos, but my tranny requires GL-4, which is a bitch to find locally.

Best stuff I've found so far for the trans has been royal purple 75w-90 full syn.
Tried redline a few years ago. It was a cocktail of 75w-90 and MTL... trans shifted like crap.
Only Redline stuff I use is their heavyweight shockproof (pink stuff) in the TC & rear!

[peteyturbo]

I hated the redline cocktail for the trans but I use nothing other then redline heavy shock proof changed every 10k in the t-case and rear..For 5 speed cars the best fluid I have found is NEO synthetic Racing heavy duty, but it will be notchy until it gets up to operating temp.
www.bakerprecision.com sells it, it is not cheap at 20 a qt. but well worth it imho
6 speed cars, Castrol Syntorq 75-85 (factory fill for dodge viper) or the ORIGINAL 75-85 diaqueen (not super-multi) is the way to go..

i just did mine with jim from t-tuned last weekend and we used redline, i like it so far.

[240kat]

feels great

I've used the redline for the last few flushes, but I feel like the shifting is really notchy, i.e. notchier than from the factory (to the point I put my weighted shift knob back on the car to get a better feel) so I'm going back to OEM when I change out the fluids next time

[evogsrviii]

i have redline in there now, and it feels just ok. I am thinking of going with either Amsoil or BG.

MTG should only go in the trans, you should use SVG in the t-case and rear.. Definitely mkae the switch next time!

I have been doing some research on different fluids. What reputable shop recommends what. So heres just some info I have come up with.

AMS high mileage trans: 50/50 mix of BG Synchro and Redline Shockproof light
AMS fresh trans: 50/50 mix of BG Synchro and Redline Shockproof heavy
Shep was also reported to recommend that combination but I haven't seen proof of that.
TRE: Against the idea of any shockproof use unless its a race only car. After several trans fluid changes the shockproof stuff will start to block oiling passeges inside the gearshafts.
link Recommended Transmission Oils- Team Rip Engineering

Differences of some of these fluids can be found at
Red Line Oil: Gear Lubricants.

After looking this over I intend to run a 50/50 mix of Redline MT-90 and MTL. I have a somewhat fresh transmission, all new bearings a few new gears. I can report back how that works, but I'm really not "hard" on my car so I dont plan to have any issues.

I'm running the mitsu evo MR tranny fluid in my trans and im not doing so well on it. I'm gonna be draining it and putting in a redline MTL / amsoil syncromesh mix next week and see how she runs.

FWIW I have been in dsm's so damn long and I have tried everything.. I would say for the kind of driving you do get the Amsoil MTG..Redline has not impressed me at all in the trans, ever.. My favorite gear lube for 75-90 mitsu trannies is NEO SYNTHETIC RHD.. IT's almost a miracle in a bottle, and at 20.00 a qt. it better be lol..

baker precision sells it..

i just put Amsoil mtg in my tranny and so far i like it. maybe it was because i needed to change it so bad but it shifts like a hot knife through butter.

In my DSM i ran straight pennzoil synchromesh, it was ok but sometimes hard to get into 3rd. Now I run 2 qt. of redline mtl and a half a quart of BG synchroshift 2 and it feels great and cleared up the locked out of 3rd issue for me.

FYI for anyone that cares, I switched back to diaqueen and after a few weeks of driving it feels like the redline again (but at 3x the price) Only good thing IMO is the dealer can't bitch about what kind of fluid if you're bringing the car in for warranty work (although I know I am in the minority of evos that still even have a warranty)
