Hey guys. So I bought a new trans online for my 06 GTP. The trans I took out I was going to have rebuilt for the fiero to go with the LS2 I am building. The reason I replaced it was grinding going into second and third gear. The problem is, the new trans is doing the same thing from day one... Any ideas??? Already bled the clutch lines and filled with new fluid. Also, replaced both shifter cables incase one was stretched out or anything... Is it possible that the new trans also had synchro problems? Has anyone else had this issue with a new F40? Thanks!

Are you sure the clutch master cylinder is in good working order? The same problem across the new and old transmission, sounds like an external mechanical part, did you reuse the old clutch and pressure plate?

I was thinking of replacing the master cyl next. The car got a new clutch, flywheel and pressure plate when everything was out.
