An automatic transmission (1) includes a transmission housing, a hydrodynamic torque converter (5), a first brake, a second brake, an intermediate plate (6) fixedly connected to the transmission housing and with ducts for supplying the hydrodynamic torque converter (5) and the two brakes (A, B) with oil. An oil guide shell (7) is arranged between the hydrodynamic torque converter (5) and the intermediate plate (6). Oil coming from the two brakes sinks via oil ducts (39.1, 39.2, 39.3) in the transmission housing and the intermediate plate (6) via the inflow opening (40) in the oil guide shell (7). The hydrodynamic torque converter (5), via rotation, conveys the oil to the elevated oil ejection opening in the oil guide shell (7), from where the oil sinks into the tank (8) via a gap (52) delimited by the oil guide shell (7) and the intermediate plate (6).

Automatic transmission for a motor vehicle

A parking lock device for a motor vehicle transmission which comprises a transmission housing, a locking pawl mounted by a bolt to swivel on the housing and loaded by a restoring spring, a guide plate supported on the housing, and a locking element by which, in the engaged condition, the locking pawl can be locked by being supported against the guide plate. The locking pawl is arranged on the bolt with some play and, on a narrow side thereof facing toward the guide plate, has a pawl hook with a first detent element, while the guide plate has, in a swiveling area of the pawl hook, an opening with a second detent element which interlocks with the first detent element when the parking lock is disengaged.
