Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, transmission fluid pump.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Locate the transmission fluid dipstick or fill plug.
• Remove the dipstick or fill plug and check the fluid level and condition.
• If the fluid is low, add the manufacturer-recommended transmission fluid until the correct level is achieved.
• If the fluid is dirty or burnt, proceed to replace it.
  • Sub-steps:
    1. Drain the old transmission fluid by removing the drain plug.
    2. Replace the transmission filter if applicable.
    3. Reinstall the drain plug and tighten to manufacturer specifications (typically around 10-15 ft-lbs).
    4. Refill the transmission with new fluid using a fluid pump.

3. Repair or Replace TCM

• If diagnostic steps indicate a malfunctioning TCM:
  • Disconnect the electrical connectors from the TCM.
  • Remove any mounting bolts securing the TCM and take it out.
  • Install the new TCM by reversing the removal steps.
  • Reconnect the electrical connectors securely.

4. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the engine and allow it to idle.
• Monitor the transmission behavior during initial driving conditions to ensure normal operation.
