Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent electrical shorts during repair.

2. Check Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick and wipe it clean.
Reinsert it fully and then remove it again to check the fluid level.
If low, add the appropriate transmission fluid (usually ATF-type specified in the owner’s manual).

3. Inspect Gear Shift Linkage

Locate the gear shift assembly under the console.
Remove any panels or covers to access the linkage.
Visually inspect the linkage for bends, breaks, or disconnections.
If damaged, replace the linkage components as necessary.

4. Test and Replace Brake Pedal Switch

Locate the brake pedal switch, usually mounted above the brake pedal.
Use a multimeter to check if the switch is functioning (should show continuity when the pedal is pressed).
If faulty, disconnect the switch and replace it with a new one.

5. Check for Transmission Leaks

Inspect the transmission pan and seals for any signs of leaking fluid.
If leaks are found, clean the area and replace the affected seals or gaskets.
Refill the transmission fluid as necessary after repairs.
