Solution

1. Preparation

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

2. Check Transmission Fluid

Sub-step 1: Locate the transmission dipstick (usually near the back of the engine).
Sub-step 2: Remove the dipstick, wipe it clean, and reinsert it fully.
Sub-step 3: Remove the dipstick again and check the fluid level. If low, add the correct type of transmission fluid as specified in the owner’s manual.
Sub-step 4: Inspect the fluid’s color and smell. If it’s dark or has a burnt odor, a fluid change may be necessary.

3. Inspect Transmission Linkage

Sub-step 1: Raise the vehicle securely using jack stands.
Sub-step 2: Visually inspect the transmission linkage for any signs of wear, damage, or disconnection.
Sub-step 3: Adjust or replace any damaged components as necessary.

4. Test Brake Switch Operation

Sub-step 1: Locate the brake light switch, usually mounted near the brake pedal.
Sub-step 2: Disconnect the switch connector and check for continuity using a multimeter.
Sub-step 3: If defective, replace the brake switch.

5. Check Fuses

Sub-step 1: Locate the fuse box and identify the fuses related to the transmission control module.
Sub-step 2: Inspect the fuses for any signs of damage or blown elements and replace if needed.

6. Fluid Change (if necessary)

Sub-step 1: Drain the old transmission fluid using a drain pan.
Sub-step 2: Replace the transmission filter if applicable.
Sub-step 3: Refill with new transmission fluid using the funnel as per the manufacturer's specifications.
