Transmission Fluid Temperature Sensor

WARNING: This page is about a different variant/trim than selected.

Transmission Fluid Temperature (TFT) sensor is attached to transmission internal electrical harness. TCM monitors voltage across TFT sensor to determine transmission temperature. Depending on temperature, TCM controls line pressure, shift scheduling and TCC operation. TCC will not function until transmission fluid temperature is greater than 104°F (40°C). Malfunction of sensor will cause incorrect line pressure and possible lack of TCC operation.
