AT - Shock Or Noise When Engaging
AT Engagement Shock or Noise Neutralize the Engine Mounts
To cut down on engine noise and vibration, the subframe and engine mounts isolate the engine and transmission from the passenger compartment. If
any of the subframe mounts or engine mounts are binding, they can increase engagement shock, transmission noise, or engine vibration.
Before you replace an AT for an engagement shock or noise complaint, test-drive an identical known-good vehicle to make sure the shock or noise
isn't just a normal characteristic. If your service client's vehicle is worse compared to the known-good vehicle, refer to the applicable SM to
neutralize the engine mounts. If the SM has no such procedure, then follow these steps instead
1. Loosen the main engine mounting bolts until they're just finger-tight.
2. Start the engine, and set the parking brake.
3. Apply the brakes, and then shift back and forth between Drive and Reverse several times.
4. Shift to Park, and shut off the engine.
