Bad tranny mount?

Okey, Ive been running a lift with a AA SYE, and Tom Woods shaft with absolutly no vibes til this week. Im getting a vibration under acceleration. So I crawled under it this morning and checked it out. All my Ujoints are good. But when I push up on the driveshaft, my whole TC moves. Not a whole lot, but more than I think it should. Is this normal or is my tranny mount bad?


What do you think?

The mount functions as a vibration reducer--otherwise why not just bolt things metal-to-metal--but it shouldn't allow any substantial movement, replace it.
