    Downshift into 3rd grinds

    Anyone got an answer for this? T56 just put a new 5-6 and sync's in at a GM dealer less than 1K ago. Grinds with the cluth fully depressed and the down shift from 4-3 is the only time it happens. Usually after running the RPM to 4-5 thousand.

    Thanks

    High rpm use with our clutches make the hydrolics take a shit. Just did a burnout the other day (4-6K rpm) and when I was done ALL my gears were locked out temporarily(grinded once) and the clutch was stuck to the floor.

    Since you mentioned you were in high rpms your clutch hydrolics probably weren't working correctly and the clutch wasn't fully engaging, which would explain the grinding.

    Does it have the same problem after low rpm use or just normal city driving?
