Digital Transmission Range Sensor

The Digital Transmission Range (TR) sensor is located on outside of transmission at manual lever. The TR sensor opens or closes a set of 4 switches that are monitored by PCM. Internal switch signal corresponds with position of gearshift lever. TR sensor completes neutral/start and back-up lights circuits. Malfunction of TR sensor may cause harsh engagements and firm shift feel. Improper shifting or shift selection, no back-up lights, and/or no engine cranking may also result.
