Solution

1. Preparation

Gather tools and materials.
Tools Required: OBD-II scanner, socket set, transmission fluid, funnel, jack and jack stands.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before working underneath.

2. Check and Add Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the appropriate transmission fluid through the dipstick tube using a funnel until the correct level is reached.
Start the engine and let it run for a few minutes, then recheck the fluid level.

3. Inspect Transmission Linkage

Locate the transmission linkage connected to the gear shifter.
Check for any loose or damaged components.
Tighten any loose bolts and replace damaged parts as needed.

4. Test Brake Light Switch

Locate the brake light switch, typically mounted near the brake pedal.
Disconnect the switch harness and use a multimeter to test for continuity when the pedal is pressed.
If faulty, replace the brake light switch.

5. Transmission Fluid Change (If Contaminated)

Place a drain pan under the transmission to catch fluid.
Remove the transmission pan bolts and carefully lower the pan to drain fluid.
Replace the transmission filter if applicable and clean the pan.
Reinstall the pan with a new gasket and torque bolts to manufacturer's specifications.
Refill with the correct type and amount of transmission fluid.
