Solution

1. Preparation

Tools Required: OBD-II scanner, car diagnostic software, torque wrench, basic hand tools (socket set, screwdrivers).
Ensure the vehicle is parked safely and the engine is off before beginning the reset process.

2. Resetting Transmission Adaptation via OBD-II

Start the engine and let it idle until it reaches normal operating temperature.
Connect the OBD-II scanner to the vehicle and turn on the ignition without starting the engine.
Navigate to the transmission control module (TCM) section of the scanner.
Select the option for "Transmission Adaptation Reset" or similar, depending on your scanner's interface.
Follow the prompts on the scanner to confirm the reset.
Once completed, turn off the ignition and disconnect the OBD-II scanner.

3. Manual Reset (if applicable)

If the OBD-II method is unavailable, switch the ignition to the ON position without starting the engine.
Depress the accelerator pedal fully for about 10 seconds.
Release the accelerator pedal and turn the ignition off.
Wait for a few moments and then start the engine, allowing the transmission to relearn its adaptation values during normal driving.
