Transmission Fluid Temperature Sensor
WARNING: This page is about a different car, the 2001 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
Transmission Fluid Temperature (TFT) sensor is hard wired to solenoid valve body. See Figure . TCM monitors voltage of TFT sensor thermistor to determine transaxle fluid temperature. Depending on temperature, TCM controls line pressure, shift scheduling and TCC operation. Malfunction of sensor will cause incorrect line pressure and possible lack of TCC operation.
