So I just had a whole *** rebuilt transmission and a 6 puck clutch put in also take note that the pilot bearing was replaced as well. I take it out on the road... still grinds. After that I replace Master cylinder, slave cylinder, put in Honda Manual Transmission Fluid. I also did new bushings on the stabilizer... But what else on earth can make this damn thing grind I've almost replaced every single thing with the shifting in that car.

 

What parts were replaced in your "rebuilt" transmission ?
