• Refill transmission with the correct type and amount of fluid.

3. Test and Replace TCM (if necessary)

• Using a multimeter, check the voltage and ground at the TCM connector.
• If voltage and ground are present but the code persists, remove the TCM using a socket set.
• Install a new TCM, ensuring all connectors are secure and undamaged.
• Reconnect the negative battery terminal.

4. Clear Codes and Test Drive
