Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues during the reset process.

2. Clear Diagnostic Codes

Reconnect the OBD-II scanner to the vehicle’s diagnostic port.
Follow the scanner prompts to clear any stored DTCs related to the transmission.
Disconnect the scanner once the codes have been cleared.

3. Reset the Transmission Control Module (TCM)

Reconnect the battery terminals securely.
Start the engine and let it idle for a few minutes.
Drive the vehicle for about 10-15 minutes to allow the TCM to recalibrate and adapt to driving conditions.

4. Check the Transmission Fluid

While the engine is running, check the transmission fluid level using the dipstick.
- If low, add the manufacturer-recommended transmission fluid until it reaches the correct level.

5. Final Check

Perform a brief test drive to ensure that the transmission light remains off and that the vehicle shifts smoothly.
