Solution

1. Preparation

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

2. Check and Refill Transmission Fluid

Locate the transmission dipstick.
Pull the dipstick out and wipe it clean with a lint-free cloth.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the recommended transmission fluid (consult owner's manual for specifications).
Inspect for any leaks around the transmission pan and seals.

3. Inspect and Repair Transmission Linkage

Locate the transmission linkage which connects the gear shifter to the transmission.
Inspect for any signs of wear, disconnection, or damage.
If damaged, replace the linkage with the correct OEM part.
Ensure all connections are secure and properly adjusted.

4. Test and Replace Brake Pedal Switch

Locate the brake pedal switch, typically mounted near the top of the brake pedal.
Test the switch for continuity with a multimeter; if faulty, replace it.
Adjust the new switch if necessary to ensure it engages properly when the brake pedal is pressed.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals securely.
Start the engine and allow it to warm up.
Attempt to shift through the gears to check if the issue has been resolved.
