If low, add the recommended transmission fluid type (check owner’s manual for specifications).
If contaminated, proceed to a fluid change.

3. Inspect Gear Shift Mechanism

Remove any panels around the gear shift lever for access.
Inspect the connections and wiring for any signs of wear or damage.
Ensure the gear shift lever moves freely without obstruction.

4. Update Software

Connect the vehicle to a Wi-Fi network.
Check for any available software updates in the vehicle’s settings menu.
Follow prompts to install updates if applicable.

5. Reconnect Battery

Reconnect the 12V battery and ensure tight connections.
Start the vehicle and observe if shifting issues persist.
