So my my tranny refuses to shift at high RPMs. It gives a loud bassy grinding vibration noise. What is it? Bearings or synchros?
Clutch is fine.
How do I know if I have a bad throwout bearing or synchros?
Does the tranny need to come down to fix this junk?
Also if I'm in 4th, press down on the clutch and rev the engine the vibration/grind is there.

saw someone post something about possible broken fingers on the pressure plate once. Jacking up the rear and starting the car and putting it in 3rd or 4th with the clutch all the way in and no parking brake and no foot brake, the tires should not move. If something in the clutch is not disengaging the clutch all the way the tires may rotate slow. This could help ID if it's trans or clutch system related
