Went back to the dealer. He said he was mistaken, and the tech only put fuel cleaner in the tank.. no machine was used.

Went for a drive with the service manager. He said it was the torque converter in partial lockup, and this is not a problem during the breakin period. He said should clearup by 1000 miles or so.. So I guess I'll wait a few weeks and see.

Anybody else notice this shuddering during breakin?
