Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, screwdrivers, transmission fluid, funnel, multimeter, and safety 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 (if applicable) and remove it.
Sub-step 2: Wipe the dipstick clean and reinsert it to check fluid level.
Sub-step 3: If low, add the appropriate type of transmission fluid to the fill mark.
Sub-step 4: If the fluid is burnt or discolored, consider a complete fluid change.

3. Inspect Transmission Linkage

Sub-step 1: Locate the transmission linkage on the side of the transmission.
Sub-step 2: Check for any loose or disconnected cables; tighten or reconnect as necessary.
Sub-step 3: Adjust the linkage as per the manufacturer's specifications if misaligned.

4. Test Brake Light Switch

Sub-step 1: Locate the brake light switch on the brake pedal assembly.
Sub-step 2: Use a multimeter to check for continuity when the brake pedal is pressed.
Sub-step 3: If faulty, replace the brake light switch with a new one.

5. Inspect Electrical Connections

Sub-step 1: Disconnect the negative battery terminal to ensure safety.
Sub-step 2: Clean any corrosion on battery terminals and connections.
Sub-step 3: Reconnect the battery terminal and check for proper voltage.

6. Check for Leaks and Damage

Sub-step 1: Inspect the transmission pan and seals for any signs of leakage.
Sub-step 2: Tighten bolts on the transmission pan if they are loose.
Sub-step 3: If damage is found, replace the transmission pan or gaskets as required.
