Solution

1. Preparation

Gather the necessary tools: socket wrench, safety gloves, and safety glasses.
Ensure the vehicle is parked on a flat surface with the engine off and the parking brake engaged.

2. Disconnect Battery

Using a socket wrench, loosen the nut on the negative battery terminal.
Carefully disconnect the negative battery cable and tuck it away to prevent accidental reconnection.

3. Wait for Reset

Allow the vehicle to sit for at least 10 minutes. This duration allows the electrical system to discharge completely and resets the TCM.

4. Reconnect Battery

Reconnect the negative battery terminal, ensuring it is firmly secured and that there is no corrosion.
Tighten the nut with the socket wrench without over-tightening, as this may damage the terminal.

5. Engine Start and Idle

Start the engine and let it idle for approximately 5 minutes. This allows the TCM to recalibrate and learn the new settings.

6. Test Drive

Take the vehicle for a test drive under various conditions (stop-and-go traffic, highway speeds) to ensure the transmission operates smoothly and the issues are resolved.
