Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, flathead screwdriver, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.

2. Disconnect Battery

Sub-steps:
1. Open the hood and locate the vehicle's battery.
2. Using a socket wrench, disconnect the negative terminal of the battery to reset the vehicle's electrical systems.
3. Wait for at least 10 minutes to allow all electronic systems, including the transmission control module, to reset.

3. Reconnect Battery

Sub-steps:
1. Reattach the negative terminal to the battery and tighten it securely.
2. Ensure that all connections are clean and free of corrosion.

4. Relearn Transmission Parameters

Sub-steps:
1. Start the engine and allow it to idle for a few minutes.
2. Shift through all the gears (Park, Reverse, Neutral, Drive, and back to Park) several times to allow the transmission to relearn its shift points.
3. Take the vehicle for a test drive, varying speeds and driving conditions to ensure proper operation.

5. Clear Codes (if necessary)

Sub-steps:
1. Use the OBD-II scanner to clear any DTCs if present.
2. Verify that no new codes appear after the reset and relearn process.
