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 shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set.
Remove the transmission fluid pan using a socket set, taking care to catch any fluid in a drain pan.
Inspect the fluid for contaminants; if dirty, replace with manufacturer-recommended transmission fluid.
Reinstall the pan and tighten bolts to the manufacturer's torque specifications (usually around 10-12 Nm).
Refill the transmission with new fluid through the dipstick tube or fill port.

3. Inspect and Adjust Gear Shift Linkage

Tools Required: Wrench set, alignment tool (if necessary).
Locate the gear shift linkage under the vehicle.
Visually inspect for wear or misalignment. Adjust or replace components as necessary.
Ensure the linkage is properly connected and secured.

4. Test Brake Pedal Switch

Tools Required: Multimeter.
Locate the brake pedal switch and check for continuity using a multimeter.
If faulty, replace the brake pedal switch with a new one.
