Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Lift the vehicle securely using jack stands if necessary.

2. Inspect and Replace the TFT Sensor

Locate the TFT Sensor:
- Find the sensor on the transmission; it is typically located near the valve body.
Remove the Old Sensor:
- Disconnect the wiring harness from the sensor.
- Use a socket set to remove the bolts securing the sensor.
- Carefully pull the sensor out of the transmission.
Install the New Sensor:
- Apply a small amount of transmission fluid to the O-ring of the new sensor to ensure a proper seal.
- Insert the new sensor into the transmission and secure it with bolts. Torque the bolts to the manufacturer’s specification (usually around 10-12 ft-lbs).
- Reconnect the wiring harness to the new sensor.

3. Fluid Check and Replacement

Check Transmission Fluid:
- Remove the transmission dipstick and check the fluid level; add fluid if necessary.
- If the fluid is burnt or contaminated, consider a complete fluid change.
Refill Transmission Fluid:
- Use the manufacturer-recommended transmission fluid (typically Toyota ATF WS).
- Fill the transmission to the correct level as indicated on the dipstick.

4. Final Checks

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Check for leaks around the sensor and ensure the fluid level is correct.
