I just put in an ACT 2600lb with Fedanza flywheel on my 94 Civic (B16A). I have done this before and never had anything like this. I have about 350 miles on it. When I put it in revers and go to back up it shakes really hard, kinda like if something was binding or the motor mounts were out. I didn't see anything wrong with the mounts. It also happens when I take off in first from a dead stop. Other then that it's fine, shifts fine and everything.

Is the clutch sticking? I also herd this could be clutch chatter, but how do I get rid of it?
Could the clutch pedal need ajusting?

Thanks guys for any help you can give me, I really don't wanna drop this tranny again.
