Solution

1. Preparation

Gather tools such as an OBD-II scanner and a multimeter.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery for safety purposes.

2. Battery Disconnection

Disconnect the negative terminal of the battery using a socket wrench.
Wait for at least 10 minutes to ensure the vehicle's electrical system resets.

3. Transmission Adaptive Reset via OBD-II Scanner

Reconnect the battery terminal securely.
Turn the ignition to the "On" position (do not start the engine).
Connect the OBD-II scanner to the diagnostic port.
Select the option to perform a transmission adaptive learning reset within the scanner's menu, following the prompts.
Confirm the reset and wait for the process to complete (this usually takes a few minutes).

4. Test Drive

Start the engine and allow it to idle for a few minutes.
Drive the vehicle through various driving conditions (stop-and-go traffic, highway speeds) to allow the transmission to relearn shifting patterns effectively.
