Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Check Transmission Fluid

Locate the transmission dipstick (if applicable) and remove it.
Wipe it clean, reinsert it, and pull it out again to check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage under the vehicle.
Inspect for any visible damage or looseness in the connections.
Adjust the linkage as necessary to ensure proper alignment and operation.
Tighten any loose fasteners to the manufacturer's torque specifications.

4. Test and Replace Brake Pedal Switch

Locate the brake pedal switch and inspect its operation.
Disconnect the wiring harness and use a multimeter to test for continuity when the brake pedal is depressed.
If faulty, replace the brake pedal switch with a new one.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check for error codes again using the OBD-II scanner.
Attempt to shift through the gears to verify proper operation.
