Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: OBD-II scanner, battery terminal wrench.

2. Connect OBD-II Scanner

Plug the OBD-II scanner into the vehicle's diagnostic port, typically located under the dashboard on the driver's side.
Turn the ignition key to the "On" position without starting the engine.

3. Reset Adaptive Values

Navigate the scanner menu to find the option for transmission control module (TCM) functions.
Select the option to reset or clear adaptive values.
Follow on-screen prompts to confirm the reset.

4. Battery Disconnect

Use the battery terminal wrench to disconnect the negative battery terminal.
Wait for approximately 10-15 minutes to allow the system to reset completely.
Reconnect the negative battery terminal, ensuring a secure connection.

5. Initialization

Start the engine and let it idle for a few minutes.
Shift through all gears (Park, Reverse, Neutral, Drive) to allow the transmission to adapt to new settings.
Drive the vehicle for about 15-20 minutes to let the TCM relearn the adaptive parameters.
