Is the new trans mount the same height as the old one? If not you changed the angle, and caused a vibration. The vibration will (over time depending on how bad it is) either destroy your tailshaft bearing or your pinion seal.

Yeah, you want to make sure the one you swap in will have the same height as the one you swap out.
