1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle’s battery to prevent electrical shorts.
• Ensure the vehicle is on a level surface and use wheel chocks for safety.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, 10mm socket, fluid catch pan.
• Sub-steps:
  1. Remove the transmission fluid drain plug using the 10mm socket and allow fluid to drain completely into the catch pan.
  2. Inspect the old fluid for metal shavings or burning smell, which may indicate more severe damage.
  3. Replace the drain plug and torque it to the manufacturer’s specifications (typically around 25 Nm).
  4. Use the fluid pump to refill the transmission with the recommended transmission fluid type (usually specified in the owner’s manual).

3. Inspect and Repair Wiring

• Tools Required: Multimeter, electrical connector cleaner.
• Sub-steps:
  1. Visually inspect the wiring harness connected to the TCM and transmission for any signs of wear, fraying, or corrosion.

  3. Clean any corroded connectors with electrical cleaner and reconnect securely.
  4. Repair or replace any damaged wiring as necessary.

4. Replace TCM (if necessary)

• Tools Required: Screwdriver set, torque wrench.
• Sub-steps:
  1. Locate the transmission control module, which is typically found near the transmission.
  2. Disconnect the electrical connectors from the TCM.
  3. Remove any mounting screws and carefully take out the TCM.
  4. Install the new TCM by reversing the removal steps, ensuring all connections are secure and properly seated.
  5. Torque the mounting screws to the manufacturer’s specifications.

5. Clear Codes and Test Drive

• Tools Required: OBD-II scanner.
• Sub-steps:
  1. Reconnect the vehicle’s battery.
  2. Use the OBD-II scanner to clear the P0700 code and any other related codes.
  3. Start the vehicle and conduct a test drive to ensure that the transmission operates smoothly without triggering any new error codes.
