Solution

1. Preparation

Gather tools and parts needed for the reset process.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative terminal of the battery to reset the TCM.

2. Disconnect Battery

Use a socket wrench to loosen and remove the negative terminal bolt from the battery.
Secure the terminal away from the battery to avoid accidental contact.

3. Wait Period

Allow the vehicle to sit for at least 10-15 minutes to ensure all electrical systems reset.

4. Reconnect Battery

Reattach the negative terminal to the battery and tighten the bolt securely with a socket wrench.
Ensure there is no loose connection.

5. Test Drive

Start the vehicle and let it idle for a few minutes.
Gently drive the vehicle through various speeds and conditions to allow the TCM to relearn its shift points.
