Abstract

A solenoid assembly for providing control over fluid pressure distribution in a transmission, where the solenoid assembly includes a sleeve, a valve portion substantially contained within the sleeve, an armature located within the sleeve, a plunger connected to the armature and in contact with the valve, and a housing located within the sleeve in proximity to the armature. The armature is moveable relative to the sleeve and the housing, and the valve portion includes a valve, where the movement of the valve is controlled by the movement of the armature. The valve is biased towards an open position to provide a fluid pressure balance between multiple ports.
