Position sensor body assembly
A transmission position sensor body assembly configured to be securely attached to a transmission housing includes a sensor body housing, a cap member and compression limiters. The sensor body housing has a central rim and a pair of outer receiving lobes that define a corresponding pair of bores. The cap member has a central body portion including integrally formed outer ears extending therefrom. The cam member is coupled to the sensor body. The compression limiters are coupled to the cap member at the respective outer ears and that extend through the bores of the sensor body housing. Fasteners are received through respective compression limiters. Clamping forces are transferred onto the cap member during the tightening of the fasteners to the transmission housing without acting on the sensor body housing.
