Abstract

An electronic-hydraulic control device for gearboxes of vehicles, preferably motor vehicles, includes a housing in which an electronic unit for controlling magnetic valves is accommodated. The valves are supplied with a pressure medium. The housing has a magnetic housing part in which magnetic parts of the magnetic valves and the electronic unit of the control device are accommodated and which lies outside the gearbox, and a hydraulic housing part in which hydraulic parts of the magnetic valves are located and which is positioned at least partially inside the gearbox housing.
