Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake for safety.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Note any transmission-related error codes.
Clear the codes and perform a test drive to see if they reappear.

3. Check Transmission Fluid

Remove the transmission dipstick (if applicable) while the engine is running and the vehicle is in park.
Wipe the dipstick clean, reinsert it, and remove it again to check the fluid level.
If fluid is low, add the manufacturer-recommended transmission fluid.

4. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Check for any visible damage or disconnection.
Adjust or reconnect the linkage as necessary, ensuring it engages properly with the transmission.

5. Inspect Brake Light Switch

Locate the brake light switch near the brake pedal.
Test the switch for proper function using a multimeter.
Replace the switch if it is defective or faulty.

6. Check for Fluid Leaks

Clean the transmission area and inspect for leaks.
Repair any damaged seals or lines found during the inspection.
Refill the transmission fluid if leaks are repaired.
