Hi guys i was just wondering i have a 00 Mustang and i just put a Spec stage 1 clutch kit on it... Even with the stock cluth that i had it sometimes will grind into 4 or 5th gear sometimes with the Stage one it seems it grinds into 5th once a day or 3 days i been dring a stick since day one i was wondering does anyone know any Soultions to this>?

 

Synchro is going out. Probably nota clutch issue.
