Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and fluid catch pan.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if equipped) or service port.
Remove the dipstick and wipe it clean; reinsert and check fluid level against the markings.
If fluid is low, add the appropriate type of transmission fluid as specified in the owner’s manual.
If fluid is dark or has a burnt smell, proceed to drain and replace the fluid:
- Place a fluid catch pan under the transmission pan.
- Remove the transmission fluid drain plug and allow fluid to drain completely.
- Reinstall the drain plug and refill with new transmission fluid.

3. Inspect and Repair Transmission Linkage

Visually inspect the transmission linkage for any bends, breaks, or misalignments.
If damaged, replace the linkage components as needed.
Adjust the linkage to ensure proper engagement with the transmission.

4. Test Brake Switch

Locate the brake switch, typically near the brake pedal assembly.
Use a multimeter to test the switch function; it should close when the pedal is depressed.
If faulty, replace the brake switch.

5. Recheck Electrical Connections

Inspect the wiring harness connected to the transmission for frays or disconnections.
Reconnect any loose connectors and secure any wires that may be rubbing against moving parts.
