I never had trouble with the tranny grinding or anything, I just read that the cocktail was the 'secret' for these terrible 5 speeds, I didn't know it was a bandaid. I found it interesting that even Uncle Scotty doesn't use the uncle scotty transmission cocktail.
The 6 speeds aren't so picky about fluids, are they? I think the guy said it was filled with fresh Motul, although I will be changing the fluid after the swap.
Does anyone have experience with WRX clutch/flywheel mated to STI tranny? Specifically 2002 WRX clutch and 2004 STI trans. Some people say I need an STI sized clutch..
