When in drive, the axles are under torque and the movement to twist can be converted to lift/fall if the engine and trans are not supported properly, AKA mounts/bushings/etc. If this results in metal to metal contact a vibration may be felt. This could be thg result of improper re installation of trans/other parts. Another question may be are you sure the trans is starting in 1rst gear? If it starts in higher gear this may be a source of extra strain producing a vibration.
