Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Set the parking brake and ensure the vehicle is in 'Park' mode.
Gather tools: OBD-II scanner, laptop (if needed for software access), and any necessary software to interface with the vehicle.

2. Connect the OBD-II Scanner

Plug the OBD-II scanner into the diagnostic port located under the dashboard.
Turn the ignition to the "On" position without starting the engine.

3. Access Transmission Adaptation Settings

Navigate through the scanner's menu to find the transmission control module (TCM).
Select the option to view adaptation values.

4. Reset Adaptation Values

Look for the option to reset or clear the adaptation values.
Confirm the reset when prompted by the scanner.
Wait for the process to complete, which may take a few minutes.

5. Perform a Transmission Relearning Procedure

Start the engine and allow it to idle for a few minutes.
Drive the vehicle in various driving conditions (stop-and-go, highway speeds) to allow the TCM to relearn shifting patterns.

6. Verify Operation

After the relearning process, check for any error codes again using the OBD-II scanner.
Test drive the vehicle to ensure smooth shifting and proper operation.
