Looking for all EVO 8, 9 people with 6 speed still.

Pretty interesting stuff^ if it makes a difference to anyone following my experimenting with it, when I fill my Mr trans with Motul, I put about 2.5-2.6 quarts in. And let drip until I had time to hurry and put the fill plug back in. So I know it's more than the 2.3 that the manual says to have.

Great thread.
I recently bought a fairly stock IX MR with 36k on it. Already did one track day (pretty much all fourth gear) and plan on going e85 next spring. Looks like I'll be doing a trans oil cooler over the winter.

Mine EVO IX GSR is around 400hp with 6-speed gearbox and never had any trouble. Obviously I service my car when required and check it sometimes to see if everything is still ok.

I've been running Motul for about 2-3k miles now. And it got rid of my 4th gear grind and shift way better too. I've ran Pennzoil Syncronesh, which is horrible. It's a quick way to ruin your trans. OEM was alright, can't go wrong. Amsoil MTG was good, I ran that the most. But Recently I switched to Motul 300- 75w90 and it's like magical how nice my trans is now. And no grinds now either. So for now, Motul had my vote!

It'll be nice if it holds! I had all these plans to take stuff apart this winter but since my 6 speed isn't broken I don't have a reason too. I plan on a lot of drag racing in the future, trying for a low 11 on 93 octane, then possibly 10's on e85 next year, all with a 6 speed.

The cases for the 5 speed and 6 speed are completely different. They obviously have to live in the same space, so dimensionally they're the same. But the 6 speed case has cooling fins on it and it's made by AISIN....not sure who makes/made the 5 speed, but it was a different vendor IIRC.
THe reason I liked the SynTorq LT is because it was a low temperature formulation for the NV4500 transmissions, since they were susceptible to heat problems...one of the issues that plagues the 6 speed with only 2.3 liters of fluid in it compared to 3 on the 5 speed. You can't get SYnTorq LT in the states, but it's actually the factory fill for Dodge Vipers. You can get it at any Dodge dealer.
I haven't driven my new Shep 6 speed, but you know that I am itching to whenever my build gets done

My OEM 6 speed always ground 2nd gear. Annoyed the **** outta me, so at 12,000 miles I threw in some SynTorq LT by Castrol. It's a 75W-85 just like OEM and it did wonders for the car, but it required more frequent transmission fluid changes to keep it feeling "good." Got 175,000 miles on the old 6 speed, no issues and no grinding with around 330whp on an MD.

Def interested to see how your shep holds up, and good info too. Also, Instead of 2.3 quarts, I put about 2.5-2.7 in. I also fill my trans when it's on a slant (jack stands up front, rear on the ground.) and that's about how much fluid I get in before it starts slowly spilling out of the fill plug. So the extra fluid may be helping, I haven't seen any negative effects of that yet.

So cool! I may give that a try if the Motul doesn't work out! I wish I had the money for the shep one. I've tried contacting TRE but like everyone else says, it seems, he is hard to get ahold of.
