Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick (if equipped).
Wipe the dipstick clean, reinsert, and remove again to check fluid level.
If low, add the appropriate transmission fluid (consult owner’s manual for specifications).

3. Inspect Shift Linkage

Locate the shift linkage under the vehicle.
Visually inspect for any signs of wear, damage, or disconnection.
Reconnect or replace any damaged components as necessary.

4. Test Brake Pedal Switch

Locate the brake pedal switch.
Use a multimeter to check for continuity when the brake pedal is depressed.
Replace the switch if it doesn't function correctly.

5. Reset Transmission Control Module

Reconnect the battery and enable the ignition (do not start the engine).
Use the OBD-II scanner to clear any transmission-related error codes.
Start the engine and allow the transmission to re-adapt through normal driving conditions.
