Required tools:
* OBD-II scanner
Procedure for resetting automatic transmission adaptation:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition, but do not start the engine.
3. Open the scanner program and select your car model.
4. Go to the “Transmission” or “Automatic Transmission” section.
5. Find the “Reset automatic transmission adaptation” function. Its name may vary depending on the scanner model.
6. Follow the scanner’s instructions and click the Reset button.
7. Wait while the scanner completes the reset process. Turnaround times may vary depending on vehicle make and model.

After resetting the automatic transmission adaptation, the transmission may need to be retrained. To do this:
* Start the engine and let it idle.
* Shift the gear selector to different positions and back.
* Drive the car in various driving conditions (eg city, highway, traffic jams) for some time.
This will allow the automatic transmission to adapt to your driving style and improve gear shifting.
