Ahhhh, I see.  Let me ask, is the engine and Tcase bolted together? If so does the engine have solid mounts?

If not you better not mount the Tcase solid. Be glad the welds broke and not the Tcase.

I have solid motor mounts, but the Tcase has the rubber mounts still.

If the engine is twisting up causing the Tcase to hit the floor, you better do something with the motor mounts first.

If the Tcase is seperate from the Trans then forget what I was  about.
