Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fluid pump, and a clean container for fluid.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Fluid Level Check
- Remove the transmission dipstick and wipe it clean.
- Reinsert, then remove again to check the fluid level. It should be within the marked range.
Fluid Replacement
- If low, use a fluid pump to add the appropriate type of transmission fluid (consult the owner’s manual for specification).
- If the fluid is burnt or contaminated, proceed to drain the transmission:
  - Place a clean container under the transmission pan.
  - Remove the transmission pan bolts and carefully lower the pan.
  - Allow the old fluid to drain completely.
Replace Filter (if applicable)
- Remove the old transmission filter and replace it with a new one (if equipped).
- Clean the pan and install a new gasket before reattaching the pan.

3. Inspect and Repair Gear Shift Linkage

Visual Inspection
- Inspect the linkage connecting the gear shifter to the transmission.
- Ensure there are no broken or disconnected components.
Adjust or Replace Linkage
- If misaligned, adjust the linkage as necessary.
- Replace any damaged parts if needed.

4. Test Brake Light Switch

Check Functionality
- Use a multimeter to check if the brake light switch is functioning correctly.
- If not, replace the brake light switch.

5. Reconnect Battery

Reconnect the battery and ensure all connections are secure.
