Transmission Range (TR) Sensor

The TR  sensor connects to the TCM  through wiring inside the lead frame module assembly.

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

Refer to Figure at the beginning of this procedure for the location of the TR  sensor.
