Abstract
An electro-hydraulic controller having a plurality of solenoid operated valves mounted in inlet and outlet ported valving cavities on a non-metallic manifold block. The manifold block has inlet and outlet ports sealed by a gasket for communication with corresponding ports in a metallic base to which the manifold block is attached. The base is sufficiently rigid to resist prohibitive deflection when exposed to the forces of fluid pressure when secured over the open hydraulic channels of an automatic transmission shift circuit deck. The non-metallic manifold may be fabricated to “Net Shape” without costly secondary operations to achieve critical dimensions.
