Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Fluid Inspection and Replacement

Sub-steps:
1. Remove the transmission dipstick and check fluid condition; it should be red and not burnt.
2. If fluid is low, use a funnel to add the correct type of transmission fluid (Toyota ATF WS) until it reaches the proper level.
3. If fluid is dark or contaminated, consider a transmission fluid change.
4. To change the fluid, locate the transmission drain plug, place a drain pan underneath, and remove the plug to drain the old fluid.
5. Replace the drain plug and refill with fresh transmission fluid via the dipstick tube.

3. Shift Linkage Adjustment

Sub-steps:
1. Locate the shift linkage under the vehicle.
2. Inspect the linkage for any damage or disconnection.
3. Adjust the linkage according to the manufacturer's specifications if misaligned.
4. Secure all connections and test the shifting mechanism.

4. Brake Light Switch Inspection

Sub-steps:
1. Locate the brake light switch, typically mounted near the brake pedal.
2. Disconnect the electrical connector from the switch.
3. Test the switch with a multimeter; it should show continuity when the brake pedal is pressed.
4. If faulty, replace the brake light switch and reconnect it.
