Solution

1. Preparation

Tools Required: OBD-II scanner, vehicle owner's manual.
Ensure the vehicle is parked on a level surface.
Turn off all electrical accessories (radio, lights, etc.) to avoid any interference during the reset process.

2. Reset the Transmission Control Module (TCM)

Connect the OBD-II scanner to the vehicle’s diagnostic port, typically located under the dashboard near the steering column.
Turn the ignition key to the "On" position without starting the engine.
Follow the scanner's prompts to navigate to 'Transmission Control Module' settings.
Select the option to reset or clear the TCM memory. This may vary depending on the scanner model; consult the scanner manual for specific instructions.
Disconnect the OBD-II scanner and turn off the ignition.

3. Cycle the Ignition

Wait for approximately 10 seconds after disconnecting the scanner.
Start the vehicle and allow it to idle for a few minutes to let the TCM relearn the shift points.

4. Final Checks

Take the vehicle for a test drive to ensure that the transmission shifts smoothly.
Monitor for any warning lights reappearing on the dashboard.
