Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for at least 10 minutes to reset the system.

2. Reconnect Battery

Reconnect the positive terminal of the battery first.
Ensure connections are tight and secure.

3. Perform Transmission Reset

Start the engine and allow it to idle for a few minutes.
Shift through all gears (P, R, N, D) slowly and pause for a few seconds in each position to allow the transmission to recalibrate.
Drive the vehicle under various conditions (light acceleration, hard acceleration, and coasting) for approximately 20 minutes to allow the transmission to learn the new driving patterns.

4. Scan for Error Codes

After the drive cycle, use the OBD-II scanner to check if any new error codes have appeared.
Clear any error codes to finalize the reset process.

5. Verify Transmission Function

Perform a test drive to ensure smooth shifting and proper transmission response.
