Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, transmission funnel, and rags.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Transmission Fluid Check

Remove the transmission dipstick (if applicable) and wipe it clean.
Reinsert the dipstick, then 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.
Inspect the fluid for clarity; if it appears dark or smells burnt, a fluid change is necessary.

3. Inspect Transmission Linkage

Locate the transmission linkage and visually inspect it for damage.
If misaligned, adjust the linkage as needed to ensure proper engagement.
Tighten any loose bolts securing the linkage.

4. Check for Error Codes

Use the OBD-II scanner to retrieve any transmission-related codes.
If codes are present, note them down for further diagnosis.
Clear any codes and test drive the vehicle to see if the issue persists.

5. Brake Switch Inspection

Locate the brake switch and check its operation by pressing the brake pedal.
If the switch is faulty, replace it with a new one.
