tranny fluid change for X
I heard a rumor in another thread that mitsu is aware of the notchy problem and has been investigating redline fluids as a possible solution. I don't know if this is true, but these 2 oils seem like they would be the most likely oils that they are experimenting with. MTL, which is a 70W80 sounds like it would be a good fit. Also check out the lightweight gear oil, which is a 75W80. I believe that either one of these would be fine for the car, and both are the same weight, with the exception that the MTL has better cold flow properties. I am considering changing over to this, but need to do more research first. BTW for anyone not aware, unlike the 8 and 9, the X calls for a 75W80 transmission fluid. Let me know what you guys think.

Although admittedly never owned an Evo, I've also had problems with notchy gearboxes in the past (not by abuse). I was trying to find a fix for my Audi's grinding gearbox six years ago when someone recommended Amsoil. After locating the importer, I paid him a visit and he suggested I used Redline instead. The problem was 90% fixed and I've always used MTL on manual transmissions since (I've been using it on my 996 for over 2 years now without any issue). It's a great product and it is certainly worth a try. As far as gear oil is concerned, I was very happy with the Redline 75W90NS but that was on a "yuppie" quattro drivetrain. The 75W90 (no NS) which is for LSDs might suit some of Evo's diffs better.

AMSOIL MTG is Specifically designed for Synchro Mesh Transmissions..

Thanks, Doc

Hey Oil Doc, can you PM me the cost? I don't own an evo yet, but I have another car that needs a good 75w90 Synthetic fluid that is compatible with brass synchro's. I'm running some Pennzoil synchromesh and I like how it performs when cold... but when it gets warm it gets pretty notchy.

Doc, that comparison really sold me. I already run AMSOIL for my engine oil, and wanted to run it in the tranny but coudn't find a 75W80, which is was the X calls for. It's different for the 9, which called for the typical 75W90, and I really want to stay with the correct weight/viscocity for my tranny. Do you guys have a competition grade/top of the line tranny fluid in this weight? I want the best stuff that you guys got. Thanks.

The MTG does meet both Specs.... I have sold a lot ov EVOm members that exact fluid and not had one complaint... I think if there was a problem, it would be all over the boards....
Even the one's I have switched over that were running MT90 said they noticed a difference especially when the tranny is still cold..
I have a contact that is former DSM and will double check with him... He went to work for AMSOIL a few months back..

I am sorry, some how I missed this.... Please send me eith a PM or Email is Preferred, on what your car is, I have several fluids that fit different applications..
It is easy to sell someone what they want, I want to make sure it is the proper fluid...
Thanks, Doc

......................waiting for a EVO X owner to try this and let me know how it works. Today it was like 80 degrees out and my tranny shifted like butter. So the cold in my opinion really has a effect on the notchyness of my trans.

But doesn't the evo8 and 9 call for a 75W90? MTG is the correct manufacturer specified weight for that application, but the X is different in that it calls for a 75W80. Is it safe to run that stuff? I asked mitsu corporate and they said that using any fluid other than the factory fluid will void the warranty. Can they do that? That seems ridiculous to me, but they also say that a drop in k & n filter will void the warranty as well, which is even more ridiculous.
The other question... Fluids can qualify for more than 1 rating... I have an oil that will qualify for a Straight 30 weight and a 10W-30 ...
Remember my gear lube tests ?....

Look at the graphs where these gear lubes start and end up... I can put Maple Syrup in a bottle, add a little Sulpher for sniff factor and call it gear lube and put any grade on it I want to... No Governing Body to stop me..
