Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, multimeter, flashlight, and possibly a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Add Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean with a lint-free cloth, then reinsert and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid (consult the owner's manual for specifications).
Check the fluid condition; it should be a clear red color. If dark or burnt, consider a fluid change.

3. Inspect Brake Pedal Switch

Locate the brake pedal switch; it is usually near the top of the brake pedal assembly.
Use a multimeter to test the switch for continuity. If it does not work, replace the switch.
Reinstall the new switch and reconnect the battery.

4. Examine Gear Shifter Mechanism

Remove the center console cover if necessary to access the shifter assembly.
Inspect for any obstructions or damage to the mechanism.
Lubricate moving parts if necessary and ensure proper alignment.

5. Check Transmission Control Module (TCM) Connections

Locate the TCM, usually found near the transmission or under the driver’s seat.
Inspect the wiring harness for any signs of damage or corrosion.
Clean connections with electrical cleaner and reconnect securely.
