Guys, I posted this in the other forum because I believe Shep and TRE visit that site more, so I needed a little more exposure. so most likely you will have to follow it there.

Hey guys,
This is an open invitation to any tranny rebuild shop that believes they can resolve my notchy shifting once and for all.
I will do everything in my power to document every stage of my quest. While I wouldn't consider the shifting quality to be junk, it definately doesn't shift smoothly at all especially as a DD. I have aprox 24k miles and am sick of tired of waiting for it to smooth out. Tried Amsoil and it helped a bit. I would normally contact the vendors directly as I have done with previous vehicles and ask for quotes...But this time I want it to be as public as possible.
Below are my symptoms/expectations:
2008 Evolution X GSR Transmission
Vehicle Build Date = NOV 2007
Miles on tranny = ~24,000
Current power level unknown - car is stock with Testpipe and EcuFlash self tune...guess 280-300whp (trapped 108 in 1/4 mile)
Issues:
Moderately to severely NOTCHY shifting during N-1, 1-2, and 2-3 shifts especially at LOWER rpms. Higher rpms (>5000) considerably smoother.
I notice that the “notchiness” varies from day to day, temperature to temperature. >90º shifts a little smoother.
Never grinds, but I do feel some blockage at times.
My suspicions:
Factory clutch not disengaging properly..can feel car move when shifting from N-1 on flat ground. (new southbend stg 3 clutch (feramic) with minimal marcel and sprung hub awaiting install) as well as ams retaining ring and clutch line.
“Feels” like internal tranny lubrication not adequately getting to hub/sleeve/syncros
TRE stated:
Mitsu changed the hub/sleeve/syncro design after my build date. This could not be verified by Jnztuning via a CAPS search.
My expectations after rebuild:
1. Newest Mitsu hub/sleeve/syncro setup (if one exists)
2. Improved retaining pins on diff...see post: EVO X 5 Speed failures and solutions (http://forums.evolutionm.net/evo-x-engine-turbo-drivetrain/431163-evo-x-5-speed-failures-solutions.html)
3. Smooth shifting into/out of any gear at any rpm. (butter smooth would be great!!)
4. 20% stronger internals from shot peening internals (400awtq will be the max this tranny will see)
5. NO ENGRAVING or marking at all on tranny and please use sealant that resembles Mitsu sealant as I am attempting to retain the factory powertrain warranty.
6. Full support after rebuild to iron out any issues that may exist.
I do not need a full fledged race tranny that can support 800 hp...This tranny will NEVER see more than 400awtq in this car.
Let's find a fix guys!!
