So I installed my new tranny and after 240 miles around the first time I put some power to it, it developed a serious vibration. Not when moving, not drive shaft, gets worse w/ rpm, parked or moving, and will actually make the front clip move about an inch. Tranny shifts fine and motor runs good as usual. Is it possible that the pressure plate moved? or the fly wheel? I did install a new king cobra clutch kit and did NOT remove flywheel. It is definitely a rotating mass vibration/shaking. I did notice when I just removed the tranny that 3 of the 4 bolts holding to the bell were not as tight as when I installed them. Would that be enough to cause that? I still needed a wrench to loosen them. I'm lost!
