Solution

1. Preparation

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

2. Inspect and Replace the Brake Pedal Switch

Tools Required: Screwdriver, multimeter, replacement brake pedal switch.
Remove the trim panel under the dashboard to access the brake pedal assembly.
Locate the brake pedal switch, disconnect the electrical connector, and use the multimeter to test for continuity when the pedal is pressed.
If defective, remove the old switch by unscrewing it from the bracket and install the new switch.
Reconnect the electrical connector and ensure the switch is adjusted properly.

3. Check the Gear Shift Linkage

Tools Required: Socket set, torque wrench.
Inspect the gear shift linkage under the vehicle for any signs of damage or disconnection.
If damaged, replace the gear shift linkage or adjust it according to the manufacturer's specifications.
Ensure all fasteners are properly torqued to the factory specifications.

4. Inspect and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box and identify the fuses related to the transmission and brake system.
Remove and visually inspect the fuses for any blown elements.
Replace any blown fuses with the appropriate amperage rating.

5. Fill or Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, new transmission fluid (check OEM specifications).
Check the transmission fluid level using the dipstick, if available.
If low, add transmission fluid until it reaches the proper level. If dirty or burnt, consider a full fluid change.
Use the pump to replace the fluid, ensuring you follow the manufacturer's guidelines for the fluid type and capacity.
