Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Top Up Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe the dipstick clean, reinsert it, and remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid through the dipstick tube, ensuring it is at the correct level.

3. Inspect Transmission Linkage

Locate the transmission linkage; usually found near the transmission housing.
Visually inspect for any signs of wear or disconnection.
If damaged, remove the linkage bolts using a socket set, replace the linkage, and reassemble.

4. Replace Brake Pedal Position Switch (if needed)

Locate the brake pedal position switch, usually at the top of the brake pedal assembly.
Disconnect the electrical connector.
Remove the retaining clip or bolt and replace the switch with a new one.
Reconnect the electrical connector and ensure proper alignment.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and attempt to shift into gear while ensuring the brake pedal is depressed.
