Sub-steps:
1. Remove the transmission fluid dipstick and check fluid level and color.
2. If low, add the correct type of transmission fluid (e.g., Toyota ATF WS) as specified in the owner’s manual.
3. If the fluid is dark or has a burnt smell, perform a transmission fluid change.
Tools Required: Funnel, rags, transmission fluid.

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage connected to the gear selector.
2. Check for any loose or damaged components and tighten or replace as necessary.
3. Adjust the linkage to ensure it aligns properly with the transmission.
Tools Required: Wrench set, pliers.

4. Test and Replace Brake Switch

Sub-steps:
1. Locate the brake switch near the brake pedal.
2. Disconnect the electrical connector and test the switch with a multimeter.
3. If faulty, replace the brake switch with a new component.
Tools Required: Multimeter, screwdriver.

5. Check Electrical Connections and Fuses

Sub-steps:
1. Inspect all relevant fuses in the fuse box and replace any that are blown.
2. Verify battery voltage using a multimeter; it should be around 12.6 volts.
