Solution

1. Preparation

Gather necessary tools and ensure the vehicle is in a safe environment.
Tools Required: OBD-II scanner, flathead screwdriver, socket set.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Disconnect Battery

Locate the battery in the engine compartment.
Use a socket wrench to disconnect the negative terminal first, followed by the positive terminal.
Wait for at least 15 minutes to allow any residual power to dissipate.

3. Reset the TCM

Reconnect the battery terminals in the reverse order (positive first, then negative).
Insert the key into the ignition and turn it to the "On" position without starting the engine.
Wait for approximately 10 seconds, then turn the ignition off.
Start the engine and allow it to idle for a few minutes.

4. Perform Transmission Adaptation

Drive the vehicle for at least 10-15 minutes under varying conditions to allow the TCM to relearn shift patterns.
Engage both light and heavy acceleration to facilitate the adaptive learning process.

5. Check for Errors

After driving, use the OBD-II scanner to check for any transmission-related error codes.
If codes are present, address them accordingly.
