Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, flat-head screwdriver, and multimeter.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to reset the electrical system.

2. Resetting the Transmission Adaptive Learning

Reconnecting Battery:
- Reconnect the negative battery terminal after a wait of at least 10 minutes.
- Ensure the battery is secure and connections are tight.
Ignition Cycle:
- Insert the key into the ignition and turn it to the ON position (do not start the engine).
- Wait for 10 seconds, then turn the key back to the OFF position.
- Repeat this process three times (ON for 10 seconds, OFF, ON for 10 seconds, OFF, ON for 10 seconds, OFF).
Start the Engine:
- Start the engine and let it idle for about 10 minutes without any load.
- This allows the transmission control module (TCM) to begin the relearning process.
Test Drive:
- Drive the vehicle under various conditions (stop and go, highway speeds) to allow the TCM to adapt to driving habits.
- Avoid sudden acceleration or deceleration during the initial drive.

3. Final Steps

After the test drive, check for any error codes using the OBD-II scanner again. Clear any codes if necessary.
