Solution
1. Preparation
  • Tools Required:
    • Socket set
    • Torque wrench
  • Ensure the vehicle is parked securely and the ignition is off.
2. Disconnect Battery
  • Use a socket wrench to remove the negative battery terminal.
  • Ensure that the connection is completely disconnected to avoid any electrical issues.
3. Wait for Reset
  • Leave the battery disconnected for at least 10 minutes. This allows any residual power to drain from the system, effectively resetting the TCM and clearing any stored error codes.
4. Reconnect Battery
  • Reconnect the negative battery terminal and tighten it securely using the socket wrench.
  • Ensure there are no loose connections.
5. Ignition Cycle
  • Turn the ignition key to the "ON" position, without starting the engine.
  • Allow the vehicle to sit for 2-5 minutes. This will help the TCM relearn the transmission's adaptive parameters.
6. Test Drive
  • Start the engine and take the vehicle for a test drive to ensure that the transmission operates smoothly and any previous issues have been resolved.
