Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is off.
• Gather necessary tools and parts before starting repairs.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, socket set, fluid catch pan.
• Sub-steps:
  • Locate the transmission dipstick and remove it to check fluid level.
  • If the fluid is low, add the recommended transmission fluid type (e.g., ATF+4).

• Sub-steps:
  • Visually inspect the wiring harness connected to the TCM for any signs of wear or damage.
  • Use a multimeter to check for continuity in the wires.
  • Clean any corrosion from connectors with a wire brush, then apply dielectric grease before reassembling.

4. Replace Transmission Control Module (if needed)

• Tools Required: Socket set, torque wrench.
• Sub-steps:
  • Remove the screws or bolts securing the TCM in place.
  • Disconnect the electrical connectors from the TCM.
  • Install the new TCM by connecting the electrical connectors and securing it with screws, ensuring the torque specifications are met.
