Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid catch pan.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery to avoid electrical shock.

2. Check and Replace Transmission Fluid

Remove the transmission fluid fill plug and check the fluid level. If it's low, proceed to the next steps.
If the fluid is dark or has a burnt smell, drain the old fluid using a fluid catch pan.
Replace with manufacturer-recommended transmission fluid, ensuring the correct type is used.
Torque Value: Reinstall the fill plug to the manufacturer’s specifications, typically around 20 Nm.

3. Inspect and Repair Wiring and Connectors

Visually inspect the wiring harness leading to the transmission for any signs of wear, fraying, or corrosion.
Use a multimeter to check for continuity in the wires. Replace any damaged wiring or connectors.

4. Test and Replace the Transmission Control Module (if necessary)

If error codes indicate a TCM issue, locate the module (usually near the transmission).
Disconnect the battery and remove the TCM connectors.
Replace the TCM with a new or refurbished unit, ensuring all connections are secure.

5. Reassemble and Reconnect

Reconnect the battery terminals.
Ensure all components removed or inspected are reassembled correctly.
Safety Warning: Double-check that no tools or foreign objects are left in the engine bay.
