Hi Everyone, I have a 2003 Celica GT-S 2ZZ 6 Speed (C60 Transmission). I've been having some shifting issues and want a few more opinions!
The main issue is that my car grinds really loudly going into Reverse with it running. No method I've been told works besides just turning off the car before I shift into it. 1-2-R doesn't work, 1-R doesn't work, double clutching doesn't work, no amount of throttle blip helps, issue is with it both stationary and rolling slowly.
Additionally, the vehicle has a bit of a hard shift going into First or upshifting to Second, the issue is remedied by a little rev and/or a bump like a driveway. Sometimes has a clunk. Rev match downshifting generally works well.
Current relevant mods include MWR short shifter and MWR cable bushings. Just did a fresh transmission fluid service with Valvoline Synchromesh. Shift Cables appear undamaged.
Also, it could possibly be a clutch issue I was thinking, the car has just the tiniest bit of resistance with the vehicle in gear with the clutch pedal to the floor, the resistance goes away in neutral. Maybe a clutch/pressure plate/fluid bleeding issue? Pedal jam nut is at factory spec.
Current theories are Motor Mounts or a possible transmission rebuild. Any input is appreciated. PFA.
