Digital Transmission Range (TR) Sensor

The digital transmission range (TR) sensor is located on the outside of the transmission at the manual lever. The sensor completes the start circuit in PARK and NEUTRAL, the back-up lamp circuit in REVERSE and a neutral sense circuit for GEM control of 4 x 4 low engagement. The sensor also opens/closes a set of four switches that are monitored by the powertrain control module (PCM) to determine the position of the manual lever (P, R, N, (D), 2, 1).
