Abstract: A transmission system for a motor vehicle with two powered axles has an engine aligned perpendicular to the driving direction and a transmission parallel to the axis of the engine shaft and includes an angle gear housing flangemounted on the side of the transmission housing, both housings having a lubricant supply for centrifugal or splash lubrication of the corresponding gear parts. The lubricant supplies, which are separated from each other by a partition, are interconnected by at least one first partition opening which serves as a lubrication inlet and at least one second partition opening which serves as a lubrication return. The second partition opening is located not below a first horizontal plane which passes approximately through the lower edge of a shaft bearing arrangement in the partition for the connecting shaft and the first partition opening is located above a second horizontal plane which passes approximately through the uppermost second partition opening.
