摘要：
A transmission oil pump for an automatic transmission of a motor vehicle. The speed of the oil pump can be shifted by a transmission (2), that is arranged between the drive motor of the motor vehicle and the transmission oil pump, to a fast-running mode or a slow-running mode so that the oil pump can be operated at two different speed levels.
