TCC Break-In View/Restart Procedure

STANDARD PROCEDURES
The Transmission Control Module (TCM) employs a strategy which modifies Torque Converter Clutch (TCC) operation. This strategy conditions the torque converter clutch disc for optimum converter clutch engagement and feel throughout the life of the transaxle. The cycle inhibits FEMCC until six hours of PEMCC operation have taken place, or the vehicle has been driven 6,035 km (3750 miles). The cycle automatically terminates when either the time or mileage has been achieved, however, the mileage may vary slightly from vehicle to vehicle.

The TCC break-in cycle must be restarted using the DRB Scan Tool, and upon:
- Replacement of TCM on vehicle with less than 6,035 km (3750 miles) or less than 6 hours of PEMCC operation
- Replacement of torque converter assembly at any vehicle mileage

NOTE: Failure to restart the TCC Break-In Cycle upon TCM replacement in vehicles with less than six hours of PEMCC or less than 6,035 km (3750 miles), or upon torque converter replacement at any mileage, may result in vehicle shudder during certain operating conditions.

PROCEDURE
The DRB Scan Tool is required to view and/or restart the TCC Break-In cycle.
1. Connect the DRB Scan Tool to the vehicle diagnostic connector.
2. Navigate to "TCC Break-In" via Transmission/ Transmission Control Module/Miscellaneous.
