Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe the dipstick clean and reinsert it to check the fluid level.
If low, add the manufacturer-recommended transmission fluid through the dipstick tube.
If the fluid appears burnt or contaminated, drain and replace it.
To drain, remove the transmission pan bolts and carefully lower the pan.
Replace the transmission filter (if applicable) and gasket.
Reinstall the pan and tighten bolts to the manufacturer's specified torque.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage and visually inspect for damage or wear.
If misaligned, loosen the mounting bolts and adjust the linkage until it aligns correctly.
Tighten the bolts to secure the linkage in place.

4. Replace the Brake Light Switch (if necessary)

Locate the brake light switch, usually mounted near the brake pedal.
Disconnect the wiring harness from the switch.
Remove the switch from its mounting bracket.
Install the new switch in the same position and reconnect the wiring harness.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and attempt to shift through the gears.
Monitor for any warning lights and listen for unusual noises.
