Transmission Fluid Temperature (TFT) Sensor
The TFT sensor is a temperature dependent resistor that is in contact with transmission fluid in the transmission sump area.
The PCM monitors the voltage across the TFT sensor, which changes as transmission fluid temperature varies.
The PCM uses the TFT sensor signal as an input for its strategy for shifting and TCC operation. The PCM also uses the TFT sensor signal for transmission fault detection and diagnostics.
Transmission Range (TR) Sensor
The TR sensor has a set of Hall-effect sensors that have a pattern of ON/OFF states which are dependent on the PARK, REVERSE, NEUTRAL, DRIVE, 3,
2 or 1 position of the manual valve.
The TR sensor also provides signals for the starting system and the reverse lights.
The PCM uses the TR sensor signal as an input for its strategy for shifting and TCC operation. The PCM also uses the TR sensor signal for transmission fault detection and diagnostics.
Transmission Operation Overview
Transmission operation is controlled by the PCM.
Torque Converter
