Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely raised with jack stands.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Change Transmission Fluid

Locate the transmission dipstick or fill port.
Remove the dipstick and check the fluid level; add the manufacturer-recommended transmission fluid if low.
If fluid is discolored or has a burnt smell, proceed to change the transmission fluid.
Drain the old fluid using a fluid extractor or by removing the drain plug. Collect the fluid in a suitable container.
Replace the transmission filter if applicable, following manufacturer specifications.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage connecting the gear shifter to the transmission.
Visually inspect for any wear, damage, or disconnection.
If necessary, adjust the linkage according to the service manual specifications to ensure proper alignment.

4. Test Brake Light Switch

Locate the brake light switch, usually mounted near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If defective, replace the brake light switch with a new one.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and attempt to shift into reverse to check if the issue is resolved.
