Valve control system

摘要

A solenoid control system for implementation with an electronic range selection (ETRS) system that shifts a transmission range between a park position and an out-of-park position. A first solenoid assembly is operable to control a fluid valve to supply pressurized fluid to urge a valve spool toward a first position. A second solenoid assembly is operable to control a fluid valve to supply pressurized fluid to urge said valve spool toward a second position. A control module selectively energizes one of the first and second solenoids based on a transmission fluid temperature.
