Quite often the rear tranny mount gets oil / ATF soaked and goes soft and allows the tranny's tail shaft to transmit vibration .

The correct fix here is to replace the two engine side mounts and rear tranny mount _then_ jack the car up and located the 17MM ATF bolt on the center engine mount and loosen it until you can lower or raise the "L" shaped center part until it's dead centered in the hole it passes through .

I was shocked when a M-B dealer trained Mechanic didn't do this after installing my tranny ~ the vibration was -so- hash my Sweet asked if I needed a new muffler or something .

Those that couldn't figure this simple thing out usually removed it, a bad idea .
