First I'd like to say a big thanks to everyone for their input. I appreciate it and it helps a lot. I will return the favor if I find a cure for this or something else down the line.

Kaj750, DSM I believe is for Diamond Star Motors or Or maybe it's Diamond Sports Motors I don't remember exactly. I just know it's in reference to all of Mitsubishis lineup. Eclipse, 3000GT, Lancer, and their various counterparts. Someone correct me if I'm wrong.

 

DSM refers only to cars that were made in the Diamond Star Motors Plant in Normal, IL. 3000GTs and Stealths were not made there. Eclipses, Talons and Lasers were.

Drive the car normally for a few weeks to really break it in then change the tranny fluid over to BG Synchroshift (I or II). Nothing makes a DSM tranny shift like butter better than BG. I suspect the same is true for the Evo. BG I is dino oil. BGII is synthetic.

Do NOT use Redline! First of all, it has been known to wear out the bearings in DSM transmission. Second of all, it made my tranny shift like absolute ***. It would physically block me out of 3rd gear when cold.

 

dsm.. got it thanks!!

 

GM Synchromesh?

 

redline = the tranny **** ?

NO 3rd GEAR FOR YOU !!!

 

Cool thanks man. I know someone else said to use the same stuff so thanks to them too. Definitely going to try it. As for Redline I mentioned this to someone else as well cuz we had the same problem in our Supras. When warmed up it shifted smoothly but it did wear out the bearings much quicker. In fact Toyota mentioned they only recommended their factory Tranny fluid due to the build of the getrag in the Supra. Others found out the hard way.

Question: Will Mitsu give me a hard time for putting in a different tranny oil as far as warranty is concerned?

 

factory oil should be okay, why mess up the tranny with aftermarket oils?

 

Did you read any of the posts in this thread at all?

For one I don't think using an aftermarket oil that's been tested and proven will do any harm. Redline was proven to be harmful in the long run. Secondly this whole thread is about issues with the gearbox in the tranny and how it can be fixed. Therefor the possible need for aftermarket tranny fluid. If the dealership tells me flat out that changing the tranny oil would void my warranty then I probably wouldn't do it. That's an expensive piece to have to replace yourself. But I seriously don't think any harm would come from it.

 

yup! and i think it voids the warranty. i do not think it is the oil

 

The first time I put in Redline, the dealership did it for me, believe it or not.

 

I had no problem speed shifting the car when i was test driving it. Believe it or not but i took the car over 7500rpm with out the ecu stopping me and it went into the next gear very smoothly. I thought the gearbox was awesome compared to my car.

 

Eh, that is awfully strange. You should've been bouncing off the rev limiter before then. Besides that what friggin dealership let you test drive it and push it that hard? That's seriously messed up.

 

I'd like to see if you'll get a marked improvement with a different front mount. If you're missing the 1-2 shift, it might be for the same reason as the Neon guys- the entire drivetrain moves in the same direction as the shifter when you're shifting, so it's like for that split second, you can't move the shifter quite far enough to engage it properly. Hobie has set up a group buy on the Lancer front/rear mount set, if you wanna get in on it.

 

Engine and transmission movement should never affect shifting. The exterior of the shift cables (i.e. the casings) are mounted to a bracket that is mounted to the transmission. That is the reference point for movement of the cables themselves.

That is why your shifter doesn't move inside the car when you accelerate.

If the reference point were the firewall, then you would have an issue.

 

It was william lehmen on 441 in broward county in florida. Yeah i was amazed that it reved a lot higher then the redline. I really dogged the car out. I was banging the gears so much you could smell the clutch after i was done with all that high rpm shifting and launching and **** The salesman was cool about it.
