Hopefully you put a reference mark on the flexplate and t.c. as already mentioned, so you know where you were. Once in a while things can be just a hair off balance, and rotating the t.c. one bolt mount location on the flexplate can sometimes smooth it out. It's worth a shot.

 

So try a rubber/OEM trans mount -- pretty easy to do...

 

That would likely help to mask the symptom, but not cure the cause.

 

I rotated the T.C. one bolt and it did reduce the Vibration by quite a bit! Don't get me wrong there is still a noticable vibration at verying RPM's but not as bad as before. Now the car wont rattle the change around in the cup holder as bad. Anyways I am just going to drive it out for now and see what happens?
