Digital Transmission Range (TR) Sensor

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