CHEVY VIBRATION WHEN PLACED IN GEAR AND ON T

2005 Chevrolet Avalanche

Shakes or Wobbles problem
2005 Chevy Avalanche V8 Two Wheel Drive Automatic 49500 miles

A local Chevrolet Dealer recently checked the vehicle out and repoaced both motor mounts and transmission mount. Could the Flex plate, torque converter or transmission to rear end coupling cause this problem? Has GM issued any recalls on this?

There are no TSB's to the best of my knowledge. Where do you feel the vibration the most, in the seat or steering? Is the engine running smoothly or does it have a rough idle?
