  3. Repair or replace any damaged wiring or connectors using solder and heat shrink tubing as necessary.

4. Replace the Transmission Control Module (if needed)

• Sub-steps:
  1. Locate the TCM, typically found near the transmission or under the dashboard.
  2. Disconnect the electrical connectors from the TCM.
  3. Unmount the TCM from its bracket using the appropriate socket set.
  4. Install the new TCM by reversing the removal steps.
