Solution

1. Preparation

Gather tools and equipment needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick (if applicable).
Wipe the dipstick clean, reinsert it, then remove it again to check fluid level.
If low, add the recommended transmission fluid type (e.g., Toyota ATF WS).
If the fluid is contaminated, proceed to change the transmission fluid.

3. Inspect Gear Linkage

Remove any covers or panels obstructing access to the gear linkage.
Visually inspect the linkage for wear, disconnection, or damage.
Adjust or replace the linkage as necessary; ensure it moves freely without obstruction.

4. Test Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to check for continuity when the brake pedal is pressed.
Replace the brake switch if it does not function correctly.

5. Transmission Fluid Change (if necessary)

Place a drain pan under the transmission.
Remove the transmission pan bolts and carefully lower the pan.
Replace the transmission filter if applicable and clean the pan.
Reinstall the pan with a new gasket and torque bolts to manufacturer specifications.
Refill the transmission with the correct type and amount of fluid.
