Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety.

2. Check Fluid Level and Condition

Remove the transmission dipstick and wipe it clean.
Reinsert and remove the dipstick again to check fluid level.
If the fluid is low, add the appropriate transmission fluid (Toyota ATF WS).
If the fluid is discolored or smells burnt, a fluid change may be necessary.

3. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Check for any loose or damaged connections.
Tighten any loose bolts and replace damaged components as necessary.

4. Brake Light Switch Inspection

Locate the brake light switch near the brake pedal.
Ensure the switch functions correctly by checking if brake lights illuminate when the pedal is pressed.
Adjust or replace the brake light switch if faulty, as it affects the transmission safety interlock.

5. Transmission Fluid Change (if necessary)

Place a drain pan under the transmission pan.
Remove the transmission pan bolts and carefully lower the pan.
Drain the old fluid and replace the transmission filter if applicable.
Reinstall the pan with a new gasket, tightening bolts to the manufacturer's specifications (usually around 8-10 ft-lb).
Refill the transmission with the appropriate fluid.
