Transmission Fluid Temperature (TFT) Sensor
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
The transmission fluid temperature (TFT) sensor is located on the molded lead frame assembly near the shift solenoids on the main control valve body. It is a temperature-sensitive device called a thermistor. It sends a voltage signal to the PCM. The voltage signal varies with TFT. The PCM uses this signal to determine whether a cold start shift schedule is necessary. The shift schedule is compensated when the TFT is cold. The PCM also inhibits TCC operation at low TFTs and corrects electronic pressure control.
