1. A casting made of aluminum, for a motor vehicle, comprising:
a bottom wall;
at least two upper walls rising in a first direction from the bottom wall to form a passage; and
at least two lower walls extending the upper walls beyond the bottom wall in a second direction opposite the first direction, such that the upper walls and lower walls form with the bottom wall a section transverse to the passage that has the overall shape of an H,
in one or more given cross sections, at least one upper internal rib extending inside the H and transversely to the upper walls and to the bottom wall, at least one external rib extending outside the H in the extension of the upper internal rib, and at least one lower internal rib extending inside the H and in the extension of the upper internal rib,
wherein the upper internal rib and the lower internal rib are shaped such that a reduced height of the upper internal rib in a central zone of the H is compensated for by an increased height of the lower internal rib in the same central zone (ZC), the height being considered relative to the bottom wall.
