Common problems like engine tranny mounts, warnout pilot bushing, if you lubed the inputshaft before installing gearbox possible oil or grease made its way to the clutch disc, check for rear engine block oil leaks such as rear main seal. And they really want to see at least 750 miles and 1200 to 1500 clutch cycles. Somthing I do not have yet. I just purchased a inspection camera because I have a sneaky suspicion I have engine oil around the clutch disk. I will keep you informed.
