Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack and jack stands, OBD-II scanner, socket set, torque wrench, fluid pump.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission fluid dipstick or fill plug.
3. Remove the dipstick and check fluid level; add fluid as necessary.
4. If fluid is burnt or contaminated, drain the old fluid using a fluid pump.
5. Replace with the manufacturer-recommended transmission fluid (Toyota ATF WS).
6. Recheck fluid level after filling and ensure it is at the correct mark.

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage under the vehicle.
2. Inspect for any bent or damaged linkage components.
3. Adjust the linkage as necessary to ensure proper alignment; refer to the service manual for specific adjustment procedures.
4. Secure all fasteners and recheck for smooth operation.

4. Test Brake Light Switch

Sub-steps:
1. Locate the brake light switch (usually near the brake pedal).
2. Disconnect the switch connector and use a multimeter to test for continuity.
3. If defective, replace the brake light switch with a new one.
4. Reconnect the switch and verify that the brake lights function correctly.

5. Reconnect and Test TCM

Sub-steps:
1. Disconnect the battery to avoid any electrical issues.
2. Locate the TCM and visually inspect the wiring and connectors for damage or corrosion.
3. Clean any corroded connectors with electrical contact cleaner.
4. Reconnect the TCM and reconnect the battery.
5. Drive the vehicle to check if the issue persists.
