Built-in unit for a transmission control of a motor vehicle

A built-in unit (10) for a transmission control of a motor vehicle, having a substrate element (11), preferably made of plastic, on which receptacles for sensor elements and regulating elements are embodied, having stamped grids (21, 22) for electrical connection between the sensor elements and a control unit, on the one hand, and between the control unit and the regulating elements, on the other, wherein the stamped grids (21, 22) have rigid conductor tracks (23, 24) disposed parallel to one another, which are disposed at least in part in guide channels (17) in the substrate element (11), wherein the conductor tracks (23, 24) are joined to one another by means of reinforcing elements (25 through 28) extending in a plane of the stamped grids (21, 22) and formed by an injection-molding of the conductor tracks (23, 24), characterized in that at least one reinforcing element (25 through 28) can be joined to the substrate element (11).
