Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Check Transmission Fluid

Locate the transmission dipstick (if applicable).
Remove the dipstick and wipe it clean with a lint-free cloth.
Reinsert the dipstick and remove it again to check fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.

3. Inspect Linkage

Locate the transmission linkage under the vehicle.
Visually inspect for any signs of wear, damage, or disconnection.
If any components are damaged, replace them as necessary.

4. Test Clutch Operation (Manual Transmission)

With the engine running, press the clutch pedal fully.
Attempt to shift into gear. If it does not engage, further inspection of the clutch assembly may be required.
If needed, replace the clutch master/slave cylinder or the clutch disc.

5. Check Brake Pedal Switch

Locate the brake pedal switch, usually mounted near the top of the brake pedal.
Inspect for proper operation; the switch should engage when the pedal is pressed.
If malfunctioning, replace the brake pedal switch.
