Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface with the engine off.
  • Engage the parking brake for safety.
2. Resetting the Transmission Control Module (TCM)

  1. Disconnect Battery:

    • Use a socket wrench to disconnect the negative terminal of the battery.
    • Wait for at least 10 minutes to allow all systems to reset.

  2. Reconnect Battery:

    • Reconnect the negative battery terminal and ensure it is secured.

  3. Turn on Ignition:

    • Insert the key fob into the ignition or press the start button without starting the engine.
    • Allow the ignition to remain in the 'On' position for about 10 seconds.

  4. Perform Transmission Adaptation Reset:

    • Start the engine and let it idle for a few moments.
    • Shift through all gears (P, R, N, D) slowly while keeping the brake pedal depressed.
    • Drive the vehicle for a short distance to allow the TCM to relearn its shifting patterns.
3. Check for Error Codes
  • After performing the reset, use the OBD-II scanner to check if any error codes remain.
  • If any codes are present, further diagnosis may be necessary.
