The other day I noticed the gears grinding a little bit on various shifts, not every time, but enough to know something is wrong. The grinding happens intermittantly during the 1-2, 2-3, 4-5, 4-3, 2-1, and 3-2 shifts. I'm not sure what the problem may be, but certainly all those syncros would not go bad at one time. I'm hoping my problem may be with the clutch master cylinder unit. Could it not be pushing the fork in all the way?
I replaced the clutch, with a SLP LT4 unit and a LT1 disk, less than a year ago. So...I'm hoping the clutch master cylinder is the magic cure. Anybody got any advice and or clues? Thx!!!!

 

ttt Anyone? Any guesses?

 

It could just be something as simple as the clutch not fully disengaging for some reason.

 

I'm having the same problem. It only happens half the time though. I also just replaced the clutch and pressure plate with spec units. I wouldn't think every syncro all the sudden went bad at the same time. Slave cylinder is the problem, no?
