Abstract

An automatic gearbox for a motor vehicle includes a lubricating or cooling device, a hydraulic pump having a first pump connection via which, in a forward operation of the hydraulic pump, the lubricating or cooling device can be supplied with a hydraulic fluid conveyed by the hydraulic pump during forward operation and thus flows through the first pump connection, and with a parking lock, which can be moved between an engaged state and a disengaged state and has a first operating space, into which the hydraulic fluid conveyed by the hydraulic pump during forward operation can be introduced so that the parking lock is hydraulically operable and an adjustment of the parking lock from one of the states into the other state can thereby be effected.
