Solution

1. Preparation

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

2. Check Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
- If fluid is low, add the manufacturer-recommended transmission fluid.
- If fluid is dirty or burnt, a fluid change may be necessary.

3. Inspect Gear Shifter Linkage

Remove the center console trim to access the gear shifter.
Visually inspect the linkage for any signs of wear or disconnection.
Adjust or replace the linkage as necessary to ensure proper alignment.

4. Test Brake Light Switch

Locate the brake light switch near the brake pedal.
Check for proper operation; the switch should activate the brake lights when pressed.
If faulty, replace the brake light switch.

5. Inspect Transmission Control Module

Locate the transmission control module (TCM) and visually inspect for corrosion or loose connections.
Reconnect any loose wires; if the TCM is faulty, replace it according to manufacturer specifications.
