1. Preliminary inspection

First check the gearbox oil level and quality. If the oil turns black or has a burning smell, replace it immediately. Also check whether the external wiring of the gearbox is damaged or loose.

2. Diagnostic testing

Use an OBD-II scanner to read fault codes and observe the data flow from the torque converter clutch solenoid valve. If the solenoid valve responds abnormally, it may need to be replaced.

3. Solenoid valve replacement

If it is diagnosed that the solenoid valve is faulty, the transmission side cover needs to be removed and the torque converter clutch solenoid valve needs to be replaced. Popular repair forums recently recommend using original or well-known brand replacement parts.

4. TCM check and reset

If the solenoid valve is normal, check the transmission control module. In some models, the problem can be solved by resetting the TCM or updating the software.
