The transmission adapter may cause a misalignment between the flexplate and torque converter causing a pre-load condition between the two components. This concern arises during a transmission flexplate replacement.

ACTION:

Inspect and replace (if necessary) the flexplate reinforcement plate and crankshaft spacer when replacing the flexplate. In addition, replace the engine spacer during this procedure. Refer to the following Service Procedure for details.
