Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission fluid dipstick.
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
If the fluid is low, top it up with the manufacturer's recommended transmission fluid.

3. Inspect for Leaks

Tools Required: Oil catch pan and rags.
Look under the vehicle for signs of fluid leakage.
If leaks are found, trace them to their source (e.g., seals, gaskets) and replace the damaged parts.

4. Examine Gear Linkage

Tools Required: Socket set and wrenches.
Locate the gear linkage under the vehicle.
Inspect for any wear or damage; adjust or replace as necessary to ensure smooth operation.

5. Test Brake Light Switch

Tools Required: Multimeter.
Locate the brake light switch, usually near the brake pedal.
Use a multimeter to check for continuity when the brake pedal is pressed.
Replace the switch if it is faulty.

6. Transmission Control Module (TCM) Reset

Tools Required: OBD-II scanner.
After addressing any mechanical issues, connect the OBD-II scanner and clear any error codes.
Monitor for codes reappearing after a test drive.
