A833 Vibration Issue

I have the stock bell housing. I drove the car several more times coasting from 70 mph down. In neutral. motor idling, motor off. clutch in, in neutral and in gear. As long as the trans was disengaged, the vibration went away. The vibration is there at 2000 rpm and up even with car sitting still.

We had the trans completely apart. The only things needed, were the tail shaft bushing, gaskets and seals.

The vibration is weird, it pulses, even sitting still! More rpm, the worse it is.
