Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely placed in 'Park' or 'Neutral'.
Disconnect the battery to avoid any electrical shorts during repairs.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check fluid level and condition.
If low or burnt, drain the old fluid, replace it with the recommended fluid type, and check for leaks.

3. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Check for any broken or disconnected components.
If damaged, replace the linkage assembly using a socket set.

4. Test Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If faulty, replace the brake switch.

5. Check Clutch Pedal Position Sensor (Manual Only)

Access the clutch pedal position sensor.
Use a multimeter to measure the sensor's output when the clutch pedal is pressed.
If the readings are out of specification, replace the sensor.
