Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Multimeter
Transmission fluid pump (if needed)

2. Check and Replace Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick or fill plug and check fluid level.
If low, add the manufacturer-specified transmission fluid until the correct level is reached.
If the fluid is dark or contaminated, drain the old fluid using a transmission fluid pump.
Replace with new fluid, ensuring to follow the manufacturer’s recommended fluid type and quantity.

3. Inspect and Repair Shift Linkage

Locate the shift linkage under the vehicle.
Visually inspect for any disconnections or damage.
If damaged, replace the shift linkage components.
Reattach any loose connections and ensure proper alignment.

4. Test Brake Pedal Switch

Locate the brake pedal switch near the brake pedal assembly.
Use a multimeter to check for continuity when the brake pedal is pressed.
If faulty, replace the brake pedal switch.
Reconnect any wiring and ensure it is secured.

5. Check Battery Voltage

Use a multimeter to check the battery voltage; it should be above 12.4 volts.
If low, recharge or replace the battery.
Ensure all battery connections are clean and tight.
