Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, fluid catch pan, funnel, replacement transmission fluid.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts while working.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If the fluid is low or appears burnt, remove the transmission drain plug and allow old fluid to drain into a catch pan.
Replace the drain plug, ensuring it is torqued to the manufacturer's specifications (typically around 30 lb-ft).
Use a funnel to add new transmission fluid through the dipstick tube, filling to the appropriate level marked on the dipstick.
Start the engine and let it idle for a few minutes, then shift through all the gears before attempting to shift into reverse.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage under the vehicle.
Visually inspect the linkage for any signs of wear or misalignment.
If misaligned, adjust the linkage according to the manufacturer’s specifications.
Ensure all connections are secure.

4. Replace Brake Light Switch (if necessary)

Locate the brake light switch, usually near the brake pedal.
Disconnect the electrical connector from the switch.
Remove the switch by unscrewing it from its mounting position.
Install the new brake light switch and reconnect the electrical connector.
