Abstract

A microvalve device (825) for controlling fluid flow in a fluid circuit. The microvalve device comprises a body (842) having a cavity (844, 846) formed therein. An electronically controlled automatic transmission, comprising a microvalve device selectively operable to control passage of pressurized hydraulic fluid from the source to the one of a hydraulically operated brake band and a hydraulically operated clutch to operate the one of a hydraulically operated brake band and a hydraulically operated clutch.
