Eighty-Eight Royale FWD V6-3.8L SC VIN 1 (1995)
Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The Transmission Fluid Temperature (TFT) sensor is a thermistor which changes resistance based on the temperature of the transaxle fluid. A
high transaxle temperature may cause the vehicle to operate in "Hot Mode." While in "Hot Mode," shift points may be altered, 4th gear disabled
and Torque Converter Clutch (TCC) forced "ON" in 2nd, and traction control disabled.
A failure in the TFT sensor or associated wiring should cause a Diagnostic Trouble Code (DTC) PO712 or PO713 to set. In this case, engine
coolant temperature will be substituted for transaxle fluid temperature, and the transaxle will operate normally.
