1. Preparation

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

2. Check and Refill Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back and remove it again to check the fluid level.
If low, add the appropriate transmission fluid (consult the owner’s manual for specification).
Start the engine and let it idle for a few minutes, then recheck the fluid level.

3. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Visually inspect for any signs of damage or disconnection.
If damaged, disconnect the linkage from the transmission and replace it. Reattach securely.

Locate the brake pedal switch above the brake pedal.
Disconnect the wiring harness from the switch.
Remove the retaining bolt and take out the old switch.
Install the new brake pedal switch and reconnect the wiring harness.
