Transmission Range Sensor

WARNING: This page is about a different car, the 2002 Ford Escape, 2001 Mazda Tribute, and 2001 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

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