Solution
1. Preparation
  • Tools Required:
    • Wrench or socket set for battery terminal
  • Ensure the vehicle is parked safely and on level ground.
  • Wear safety gloves and goggles.
2. Disconnect Battery
  • Use the wrench or socket to loosen the negative battery terminal.
  • Carefully remove the negative cable from the battery post and secure it away from the battery.
3. Reset TCM
  • Wait for at least 10-15 minutes to allow any residual power to dissipate.
  • Reconnect the negative battery terminal, ensuring it is tightened securely.
4. Ignition Cycle
  • Turn the ignition key to the "ON" position (do not start the engine).
  • Allow the dashboard lights to come on and go through their self-check.
  • Turn the ignition off, then remove the key.
5. Test Drive
  • Start the engine and let it idle for a few minutes.
  • Take the vehicle for a test drive to allow the TCM to recalibrate its shift patterns based on driving conditions.
