Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools: OBD-II scanner, socket set, transmission fluid, funnel, and rags for cleanup.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe the dipstick clean, reinsert it, and then remove it again to check the fluid level.
If the fluid is low, add the manufacturer-recommended transmission fluid through the dipstick tube.
If the fluid is dark or has a burnt smell, drain and replace the fluid:
- Raise the vehicle using jack stands and remove the transmission pan.
- Clean the pan and replace the filter if applicable.
- Reinstall the pan and refill the transmission with new fluid through the dipstick.

3. Inspect Transmission Linkage

Locate the transmission linkage on the side of the transmission.
Visually inspect the linkage for any signs of damage or disconnection.
If necessary, adjust the linkage according to the manufacturer’s specifications.

4. Replace Brake Light Switch (if needed)

Locate the brake light switch near the brake pedal.
Disconnect the electrical connector from the old switch.
Remove the old switch and install the new switch, ensuring it is properly aligned.
Reconnect the electrical connector.

5. Reassemble and Test

Lower the vehicle from the jack stands.
Start the engine and attempt to engage reverse.
Monitor for any unusual noises or warning lights.
