  • Remove the transmission pan (if applicable) using a socket wrench.
  • Drain old transmission fluid into a catch pan.
  • Replace the transmission filter; ensure the old gasket is removed from the pan and transmission.
  • Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (usually around 8-10 ft-lbs).
  • Fill the transmission with the appropriate fluid (check the owner’s manual for type and volume).

3. Inspect and Repair Wiring/Connectors

  • Tools required: Multimeter, wire brush, electrical contact cleaner.
  • Visually inspect the wiring harness connected to the TCM for frays, corrosion, or loose connections.
  • Use a multimeter to check for proper voltage and ground at the TCM connector.
  • Clean any corroded connectors with electrical contact cleaner and a wire brush, then reassemble.

4. TCM Testing and Replacement

  • If the TCM is determined to be faulty, replace it.
  • Tools required: Socket set, torque wrench.
  • Disconnect the battery again for safety.
