Reattach the negative terminal to the battery and tighten it securely.
Ensure there is no corrosion on the terminals before reconnecting.

4. Start the Vehicle

Turn the ignition key to the "On" position without starting the engine, then wait for a few seconds.
Start the engine and allow it to idle for a few minutes.

5. Test Drive

Drive the vehicle under various conditions (stop-and-go traffic, highway speeds) to help the transmission relearn its adaptive settings.
Pay attention to the shifting patterns to confirm improvement.
