Try checking the tranny mount first. A common 3rd gen problem.

The torque arm is a long piece that runs parallel to the drive shaft from the rear end to the trans. There should be a bushing on the trans end. More likely, though, it's, as DJP mentions, the trans mount (the mount supports/cushions the tail shaft of the trans). A poly replacement for either is your best bet.

Hello
Like mentioned above check the bushing they usually get cut! And make sure the hardware to the torque arm is tightened to specs. If you do need a replacement poly bushing we also offer those for $14.99 plus S/H. If you have any other questions or concerns feel free to ask and I will be more than glad to help!
Thanks
Brad
