Abstract: A hydraulic control system of an automatic transmission includes a clutch compensator feed circuit that is in communication with clutch apply circuit exhaust fluid. The clutch compensator feed circuit receives exhaust fluid from one or more apply clutches, or other torque transmitting device(s), and feeds the exhaust fluid to the balance side of the clutch or other torque transmitting device. The clutch compensator feed circuit may be open to atmospheric pressure, such that the clutch compensator feed circuit is not pressurized with respect to atmospheric pressure.

Abstract: A hydraulic control system for a transmission of a motor vehicle includes a source of pressurized hydraulic fluid that communicates with an analog electronic transmission range selection (ETRS) subsystem or a manual valve. The ETRS subsystem includes an ETRS valve, a park servo, a park mechanism, a mode valve, and a plurality of solenoids. The ETRS and manual valve communicate with a clutch actuator subsystem that engages a one-way clutch and six clutches/brakes.

Abstract: The present invention provides a gear absolute position sensor assembly (GAPS) that senses the current absolute, position of the shift lever of a manual transmission. The sensor assembly provides data to an associated electronic controller such as an engine control module (ECM) regarding the current position of the shift lever, such as an engaged gear. The sensor assembly preferably comprises at least one Hall effect or other type of magnetic field (proximity) sensors in combination with an application specific integrated circuit (ASIC) which is supplied with data from the sensors, decodes the output of the sensors and provides an output identifying a specific engaged gear or neutral for use by vehicle or engine management electronics. The sensors are mounted proximate the shift linkage at a location where they can sense both rotation and translation.
