Abstract
A transmission for a motor vehicle includes an input shaft, a transmission pump, a transmission sump and a pump-driving element, which is preferably a drive gear. The drive gear and the transmission pump are located in the transmission sump. Power is transmitted from the input shaft to the transmission pump through the drive gear. In a preferred embodiment, power is transmitted from the input shaft to the drive gear through at least one gear, and from the drive gear to the transmission pump through a pump shaft. The drive gear is preferably at least partially enclosed by a shroud, coupled to the transmission pump, in order to separate the drive gear from transmission fluid located in the transmission sump and thereby reduce drag on the drive gear. The shroud preferably also includes a discharge port so that transmission fluid located in the shroud is expelled through the discharge port when the drive gear rotates.
