Abstract: An integrated solenoid circuit system for a motor vehicle transmission, and a method of forming the same. The system comprises a housing including a solenoid subhousing and a transmission range sensor (TRS) subhousing. The system also includes a solenoid sensor operatively located in the solenoid subhousing for sensing activation of transmission solenoids. The plurality of transmission sensors is operatively positioned in the transmission range sensor subhousing for communicating transmission states sensed by the solenoid sensor to the controller. A manifold is operatively mounted in the solenoid subhousing for energizing system components. A transmission sensor circuit operatively connects a plurality of transmission sensors to the manifold for selectively activating each of the plurality of transmission sensors in response to a sensed transmission state. The system integrates the transmission sensors, the manifold and the transmission sensor circuit into a single piece construction.
