Abstract: Disclosed is a hydraulic pressure supply system of automatic transmission for vehicles. According to an embodiment of the present invention, the hydraulic pressure supply system of the automatic transmission for the vehicles comprises a low pressure oil pump generating low pressure hydraulic pressure by sucking oil in an oil pan through a suction path, and discharging the oil to a low pressure oil path. The low pressure oil pump supplies the low hydraulic pressure to a low pressure part by controlling the hydraulic pressure through a low pressure regulator valve. A high pressure oil pump operated by an electric motor discharges some of the hydraulic pressure supplied through the low pressure oil path to a high pressure oil path by increasing pressure, and supplies the high pressure oil to a high pressure part by controlling the oil pressure through a high pressure regulator valve. A pressure sensor is installed in a recirculation path of the high pressure regulator valve, and the RPM of the electric motor is controlled by a transmission control unit based on information detected from the pressure sensor.
