After replacing the automatic transmission control unit:
Required actions:
* Programming the automatic transmission control unit: Install new software or reprogram the automatic transmission control unit in accordance with the manufacturer’s recommendations.
* Automatic transmission adaptation: Perform the automatic transmission adaptation procedure so that the control module learns the characteristics of the new transmission and optimizes gear shifting.
* Clear Trouble Codes: Clear all stored trouble codes related to the automatic transmission.
Recommended checks:
*Checking the automatic transmission fluid level: Make sure that the automatic transmission fluid level is within the acceptable range. Add fluid if necessary.
* Checking gear shifting: Test drive the car and make sure that the automatic transmission shifts smoothly and without slipping or jerking.
* Checking for leaks: Visually inspect the automatic transmission and its connections for fluid leaks.
* Scanner check: Connect a diagnostic scanner and check for fault codes or deviations in the automatic transmission operating parameters.
Cautions:
* Do not ignore the need to program and adapt a new automatic transmission control unit.
* Use only automatic transmission fluid recommended by the manufacturer.
*If you experience shifting problems or other problems with your automatic transmission after replacing it, contact a qualified mechanic.
* Keep records of the replacement of the automatic transmission control unit and the adaptations and coding performed for future reference.
By following these steps, you will ensure your new automatic transmission operates properly and prevent potential problems in the future.
