Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during electrical work.

2. Check Transmission Fluid

Remove the transmission dipstick (if equipped).
Check fluid level; add manufacturer-recommended transmission fluid if low.
Inspect fluid condition—if burnt or contaminated, a fluid change may be necessary.

3. Inspect and Repair Wiring

Visually inspect the wiring harness and connectors for fraying, corrosion, or damage.
Repair any damaged wires or connections using appropriate soldering or crimping techniques.
Ensure all connectors are seated properly.

4. Replace Transmission Control Module (if necessary)

Locate the transmission control module (usually near the transmission or behind the glove box).
Remove any mounting bolts and disconnect electrical connectors.
Install the new module by reversing the removal steps.
Ensure all connections are secure and module is properly mounted.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and verify that the check engine light is off and the transmission operates smoothly.
Conduct a test drive to confirm repair.
