Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts.
Allow the vehicle to cool down if the transmission has been recently operated.

2. Inspect Fluid and Replace if Necessary

Remove the transmission dipstick and check the fluid level.
If low, add the recommended transmission fluid (Toyota ATF WS).
If the fluid is burnt or contaminated, perform a transmission fluid change:
1. Place a drain pan under the transmission.
2. Remove the transmission pan bolts and gently pry the pan loose.
3. Drain the old fluid completely.
4. Clean the pan and replace the filter if applicable.
5. Reinstall the pan with a new gasket and torque the bolts to specifications (typically 7-10 ft-lbs).

3. Check Brake Switch and Linkage

Inspect the brake light switch:
1. Remove the cover under the steering column.
2. Locate the brake light switch and test it with a multimeter to ensure it operates correctly.
3. Replace the switch if it fails the test.
Examine the gear shift linkage:
1. Remove any covers to access the linkage.
2. Ensure that the linkage is properly connected and not damaged. Adjust or replace as necessary.

4. Test Transmission Range Sensor

Access the transmission range sensor:
1. Locate it on the transmission housing.
2. Disconnect the electrical connector and test for continuity using a multimeter.
3. Replace the sensor if it does not provide the correct readings.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check for any warning lights.
Attempt to shift through all gears while stationary and observe functionality.
