Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, fluid pump, funnel.
Remove the transmission fluid dipstick and check the fluid level.
If low or contaminated, drain the old fluid by removing the transmission pan bolts and allow it to fully drain.
Refill with the manufacturer's recommended transmission fluid type using a fluid pump and funnel until it reaches the proper level.

3. Inspect and Adjust Shift Linkage

Tools Required: Wrench set, pliers.
Locate the shift linkage connected to the transmission.
Check for any loose or damaged components and secure or replace them as necessary.
Ensure the linkage is properly adjusted according to the service manual specifications.

4. Test the Brake Light Switch

Tools Required: Multimeter.
Locate the brake light switch, typically near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If faulty, replace the brake light switch with a new one.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and attempt to shift into gear.
Perform a test drive to ensure the transmission shifts smoothly through all gears.
