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 has digital sensor (hall effect) that converts the shifter position into a bit pattern, and a micro controller that converts the 4 bit signal into a 125 Hz pulse width modulated signal.

The TR sensor also provides signals for the starting system and the reverse lights.

The PCM/ TCM uses the TR sensor signal as an input for its strategy for shifting and TCC operation. The PCM/ TCM also uses the TR sensor signal for transmission fault detection and diagnostics.
