Solution

1. Preparation

Gather tools: OBD-II scanner, vehicle owner’s manual, and a clean cloth.
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner instructions to retrieve and record any error codes related to the transmission.

3. Clear Error Codes

With the OBD-II scanner connected, navigate to the option to clear or erase error codes.
Confirm the action to reset the codes. This should turn off the transmission light if no other issues are present.

4. Check Transmission Fluid

Open the hood and locate the transmission dipstick.
Remove the dipstick, wipe it clean, reinsert, and then remove it again to check the fluid level.
If low, add the recommended transmission fluid type as per the owner's manual.

5. Recheck System

After clearing codes and checking fluid, turn the ignition to the "ON" position again.
Observe if the transmission light remains off as you start the engine and take the vehicle for a short drive.
