Resetting Adaptive Parameters

Because the PCM/TCM has the ability to adapt to various transaxle conditions, it is necessary to reset adaptive parameters after certain repairs have been performed. The adaptives can be reset using the Scan tool. The adaptives should only be reset after the following repairs have been made:
- Replacing a transaxle.
- Replacing a line pressure actuator.
- Transaxle overhaul when new clutch plates are installed.
- Replacing control valve body.
After performing a repair, the vehicle must be driven to allow the adaptives to learn new shift times and pressures before returning the vehicle to a customer.
