Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and securely lifted if needed.
• Disconnect the battery to avoid electrical shorts during work.

2. Transmission Fluid Inspection

1. Remove the transmission dipstick and check the fluid level.
2. Inspect fluid color and smell; dark or burnt fluid indicates a need for replacement.
3. If necessary, drain the old transmission fluid and replace it with the manufacturer-recommended type.

3. Wiring and Connector Inspection

1. Visually inspect the wiring harness connected to the transmission control module for frays or corrosion.
2. Disconnect the wiring harness and clean the connectors with electrical contact cleaner.
3. Reconnect the harness, ensuring a secure fit.

4. Transmission Control Module Testing

1. Locate the transmission control module (usually near the transmission).
2. Using a multimeter, check the power and ground signals according to the service manual specifications.
3. If the module is faulty, remove it and replace with a new unit following the specific torque values for the mounting bolts.

5. Reassembly and Fluid Filling

1. Reinstall any components removed during inspection and testing.
2. Refill the transmission with the correct fluid type, ensuring the level is correct.
3. Reconnect the battery before starting the vehicle.
