Solution

1. Preparation

• Gather tools and parts before starting the repair.
• Tools required: OBD-II scanner, multimeter, socket set, torque wrench, transmission fluid.
• Safety warnings: Ensure the vehicle is on a flat, stable surface and the engine is off.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick and remove it.
  2. Check the transmission fluid level; if low, add the manufacturer-recommended fluid.
  3. If fluid is dark or smells burnt, prepare to drain and replace it.
  4. Use a socket set to remove the transmission pan bolts and carefully lower the pan.
  5. Drain the old fluid into a suitable container and replace the filter (if applicable).
  6. Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications.

3. Inspect and Repair Electrical Connections

• Sub-steps:
  1. Disconnect the negative battery terminal to prevent electrical shorts.
  2. Locate the TCM connection point and visually inspect for corrosion or damage.
  3. Use a multimeter to check for continuity and proper voltage to the TCM.
  4. Repair or replace any damaged wires or connectors as necessary.
  5. Reconnect the battery terminal and clear the error codes with the OBD-II scanner.

4. TCM Replacement (if necessary)

• Sub-steps:
  1. If the TCM is determined to be faulty, locate it (usually near the transmission or under the dashboard).
  2. Disconnect the wiring harness and remove any mounting screws holding the TCM in place.
  3. Install the new TCM, ensuring it is securely mounted and all connections are reattached.
  4. Reconnect the battery terminal and scan for error codes again.
