Transmission Temperature Sensor (A/T Models)

Transmission temperature sensor monitors transmission fluid temperature and sends an input signal to PCM. Input signal is used for controlling torque converter clutch operation, overdrive shifts, low temperature shift compensation, wide open throttle shift strategy and governor pressure. Transmission temperature sensor is located in transmission valve body, incorporated into governor pressure sensor.

If transmission fluid temperature is more than 260°F (126°C), PCM forces a 4-3 downshift and engages torque converter clutch until fluid cools. Once fluid cools to less than 230°F (110°C), PCM allows a 3-4 shift. PCM prevents torque converter clutch engagement and overdrive operation when fluid temperature is less than 50°F (10°C).
