Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the vehicle's battery.

2. Inspect and Replace Brake Fluid

Check the brake fluid reservoir; if low, top off with manufacturer-recommended fluid.
If fluid is contaminated, flush the brake system and replace with new fluid.

3. Inspect and Change Transmission Fluid

Remove the transmission fluid dipstick and check the fluid level.
If low, add the appropriate transmission fluid as specified in the owner’s manual.
If the fluid is dirty or burnt, perform a transmission fluid change:
1. Drain the old fluid from the transmission pan.
2. Replace the transmission filter if applicable.
3. Refill with new transmission fluid to the correct level.

4. Check the Gear Selector and Brake Pedal Switch

Inspect the gear selector mechanism for any obstructions and ensure it moves freely.
Test the brake pedal switch:
- Remove any necessary panels to access the switch.
- Use a multimeter to test for continuity when the brake pedal is pressed.
- Replace the switch if it is faulty.

5. Reconnect Battery and Test

Reconnect the vehicle’s battery.
Start the vehicle and attempt to shift through the gears.
