Default Torque Converter Bulletin

Star Case: #S1121000005

Release Date: 6/30/11

Symptom/Vehicle Issue:
Customer indicates that the vehicle has a slight moan, drone, or rattle noise and sounds as though it is coming from the exhaust, The customer may indicate that the noise occurs under light load (1400 - 1700 engine rpm - around 40 to 60 mph)

Confirm that the noise only occurs while the torque converter is in lock-up at low speeds (around 1400 - 1700 engine RPM) at approximately 45 mph. If the noise is heard while transmission is in partial lock-up at 1400 - 1700 RPM, put the vehicle into ERS - Tow/Haul mode (deactivates MDS and torque converter in full lock-up) If the noise is unchanged, perform the following repair procedure.
