Abstract
Saturation of a secondary system pressure circuit () of a hydraulic system () of a motor vehicle transmission is earlier, in that an excess amount of oil from a primary system pressure circuit () of the hydraulic system () is not directed to a suction charging (), but rather into the secondary system pressure circuit (). This can take place via a system pressure valve () for the primary system pressure circuit (), which is configured for this function.
