How would a transmission cause that much vibration?
I would try indexing the drive shaft 90 degrees different on the rear yolk. Check the U-joints and make sure all of the caps are mounted correctly and have all of their needle bearings in place.
Like OhioMopar said, loosing a U-joint can be very violent.



The u-joint came apart, that's what caused the vibration. Now I'm getting a popping out of 4th gear condition...
