Patent number: 9080666Abstract: A hydraulic control system for a transmission is provided. The hydraulic control system includes a source of pressurized hydraulic fluid that communicates with a discrete electronic transmission range selection (ETRS) subsystem. The hydraulic control system includes first and second mode valves located downstream of a hydraulic fluid pressure source. The mode valves are supplied with fluid via one or more solenoid valves or other valves. The mode valves have a plurality of ports configured to transfer pressurized hydraulic fluid. The first mode valve transfers pressurized hydraulic fluid from the source to the second mode valve. The second mode valve transfers pressurized hydraulic fluid from the first mode valve to one of drive or reverse. An electro-hydraulic circuit for pulling the transmission out of park and putting the transmission into park is also provided. A park sensor assembly including a Hall Effect sensor switch is also provided.Type: GrantFiled: May 14, 2013Date of Patent: July 14, 2015Assignee: GM Global Technology Operations, Inc.Inventors: Todd R. Berger, Peter Donald Bock, John R. Czoykowski, Christopher J. Landino, Bradford E. Vorbeck, Stephen W. Powell
