Solution

1. Preparation

• Gather tools and materials needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, fluid catch pan, socket set.
• Remove the transmission drain plug and let the fluid drain completely into the catch pan.
• Inspect the old fluid for metal shavings or burnt odor.
• Replace with manufacturer-recommended transmission fluid (consult the owner's manual for specifications).
• Reinstall the drain plug and torque to the manufacturer's specifications.

3. Check and Repair Wiring

• Tools Required: Multimeter, wire connectors, heat shrink tubing.
• Visually inspect the wiring harness connected to the TCM for any signs of damage or wear.

• Repair any damaged wires using appropriate connectors and heat shrink tubing.

4. Test and Replace Transmission Control Module (if necessary)

• Tools Required: OBD-II scanner, socket set.
• If previous steps did not resolve the issue, use the OBD-II scanner to check for TCM-related trouble codes.
• Unbolt the TCM from its mounting location and disconnect electrical connectors.
• Install a new or reconditioned TCM, ensuring all connections are secure.
• Reconnect the battery and clear the trouble codes using the OBD-II scanner.

5. Final Reassembly
