Transmission Range Sensor: Description
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the transmission and can only be serviced by removing the valve body assembly. The electrical connector extends through the transmission case ( Fig 1).
The Transmission Range Sensor (TRS) has four switch contacts that monitor shift lever position and send the information to the PCM.
