Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Battery Disconnect

Use a socket set to remove the negative terminal from the battery.
Wait for at least 10 minutes to allow the vehicle's electrical system to reset.
Reconnect the battery terminal securely.

3. Transmission Adaptive Learning Reset

Start the engine and allow it to idle for a few minutes.
Shift through all gear positions (P, R, N, D, L) slowly and hold each position for approximately 3 seconds.
Return the gear selector to the "D" position and let the vehicle idle for an additional 5 minutes.
Test drive the vehicle to allow the transmission to relearn its adaptive values through various driving conditions.
