Solution

1. Preparation

Gather tools and materials.
Tools Required: OBD-II scanner, socket set, wrench set, safety gloves.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Connect OBD-II Scanner

Locate the OBD-II port, usually found beneath the dashboard near the steering column.
Connect the OBD-II scanner and turn the ignition key to the "ON" position without starting the engine.

3. Clear Fault Codes

Follow the scanner's instructions to read and note any fault codes.
Clear all transmission-related codes from the system.
Disconnect the scanner after clearing the codes.

4. Disconnect Battery

Open the hood and locate the battery.
Using a wrench, disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
Ensure the battery terminals are secure and not touching each other.

5. Wait and Reconnect

Allow the vehicle to sit for at least 10 minutes to ensure all capacitors in the system have discharged.
Reconnect the positive (+) battery terminal first, then the negative (-) terminal.
Tighten the connections securely.

6. Test Drive

Start the vehicle and let it idle for a few minutes.
Take the vehicle for a test drive to allow the TCM to relearn its parameters and check for proper shifting behavior.
