2. Fluid Inspection and Replacement

• Fluid Inspection:

  • Remove the transmission dipstick (if applicable) and check the fluid level.

3. Wiring and Connector Repair

• Inspect the transmission wiring harness and connectors:
  • Disconnect the harness and visually inspect for frayed wires or corrosion.
  • Repair or replace damaged wiring or connectors as needed.

4. TCM Testing and Replacement

• Test the TCM:

  • Use a multimeter to check the power and ground connections to the TCM.
  • If no voltage is present, trace the circuit back to find the fault.

• TCM Replacement:

  • If the TCM is faulty, remove it from the transmission.
  • Install the new TCM and reattach all wiring harnesses.

5. Reconnect Battery and Recheck Codes

• Reconnect the vehicle’s battery.
