Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check and Refill Transmission Fluid

Locate the transmission dipstick (if applicable) or access the fill plug.
Remove the dipstick or fill plug and check the fluid level.
If low, add the appropriate type of transmission fluid (refer to the owner’s manual).
Inspect the fluid for burnt smell or metal particles.

3. Inspect and Adjust Shift Linkage

Locate the shift linkage assembly under the vehicle.
Visually inspect for any bent or damaged components.
If necessary, adjust the linkage according to the manufacturer specifications or replace damaged parts.

4. Test Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to check for continuity when the brake pedal is pressed.
If faulty, replace the brake switch to ensure proper shifting functionality.

5. Scan and Clear Error Codes

Reconnect the battery and use an OBD-II scanner to check for transmission-related error codes.
Clear any codes if repairs were made, and perform a test drive to see if the issue persists.
