so i got some grinding in the 1-2 shift when i was finally able to get on it after ~650 miles. all of a sudden, in the past 2 days, it got horribly bad!! and not just the 1-2 shift, also the 3-4 shift. it still changes gears, but there is a loud, harsh grind while shifting fast. could this be related to my newly installed clutch?

is there an adjustable clutch quadrent? if so the asjustment might be off. if you paid a shop to install it, take it back and tell them. part of paying for a clutch job is an assurance that there wont be any problems.

well it might not be adjusted properly and therefore not allowign hte clutch disc to fully disengage from the flywheel. also, when the clutch was put in, did they put in a new cable? its a good practise to do that, unless the cable is fairly new. also did they drain the trans, and if they did what fluid did they put in? if they put in too thick or thin of a fluid it might affect the synchros.

no, the clutch is fully engaged b/c its only on the 1-2 and 3-4 shift. im 80% sure its the syncros. and i was thinking about the tranny fluid. they didnt change it. my buddy got grinding in his audi TT and he changed his fluid and it eliminated the problem all together. maybe i just need some thicker fluid?

well it hasnt been done in 4 years, and thats a maintainence item. it should help a little bit hopefully. i think it takes around 3 quarts. before you go and do it go to the shop that installed the clutch and ask their opinion.
