Solution

1. Preparation

Gather tools and materials, including an OBD-II scanner, socket set, transmission fluid, and rags.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Check Transmission Fluid

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.

3. Inspect Linkage and Cables

Locate the transmission linkage and visually inspect for wear or disconnection.
If any parts are damaged, replace them with OEM parts.
Adjust the linkage if necessary, following the vehicle service manual specifications.

4. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "on" position without starting the engine.
Read and record any error codes. Address issues indicated by the codes, such as solenoid or sensor failures.

5. Test Brake Switch (if applicable)

Locate the brake switch under the dash near the brake pedal.
Use a multimeter to check if the switch is closing when the pedal is pressed.
Replace the brake switch if it is faulty.

6. Inspect for Fluid Leaks

Look under the vehicle for any signs of fluid leakage.
Clean any spilled fluid and observe if it reappears after a short drive.
Repair any leaks by replacing gaskets or seals as necessary.
