actually, mine is an '06 tranny
I pray that I never break anything on it, it's the part of the car I have the LEAST info on, but from looking through the previous owners past threads, I believe it was something like the 06 tranny with the '06 sti driveshaft and an R180 rear diff with custom axles to retain the 5x100 hubs. Unsure of the clutch/flywheel, but I know my left leg gets tired quick in this thing
