Transmission Fluid Temperature (TFT) Sensor
The Transmission Fluid Temperature (TFT) sensor, which is integrated within the transmission wiring, is installed on the front of the valve body. It directs the transmission fluid temperature within the hydraulic pressure control circuit and transmits a signal based on that temperature to the TCM. Through this it controls gear shift, lockup and slip in response to changes in transmission fluid temperature for smooth shifting across wide fluid temperature zones.
