Weirdest herky jerkey clutch

Complain away. Sounds like you've been through a lot of work and still don't have what you want. Lots of the clutches built now are not very good quality. You have changed absolutely everything and any one component you installed could cause problems. My first thought is you have a bad pressure plate. The fingers are un even and or set incorrectly. Usually when you have a jumpy or chattering clutch it's because the flywheel or pressure plate surface is heat checked or you have a leak that causes some slipping. It will be interesting to hear others responses. Is their a Clutch Masters in your area?
