Abstract: Disclosed is an oil pressure supply system for an automatic transmission of a vehicle. According to an embodiment of the present invention, the oil pressure supply system for the automatic transmission of the vehicle supplies, a low pressure oil pump supplies oil stored in an oil pan to a low pressure part at lower pressure, and a high pressure oil pump supplies some of the low pressure oil to a high pressure part through a high oil path by increasing the oil pressure at high pressure. The invention comprises a low pressure regulator valve, a high pressure regulator valve, an orifice, a pressure sensor, and an electric motor. The low pressure regulator valve is controlled by control pressure of a first solenoid valve, and recirculates some of oil pressure supplied from a low oil path to a suction path through a first recirculation path to supply the oil pressure to the low pressure part by controlling the oil pressure. The high pressure regulator valve is controlled by the control pressure of a second solenoid valve, recirculates some of the oil pressure supplied from the high oil path to the low oil path through a second recirculation path in order to supply the oil pressure to the high pressure part by controlling the oil pressure. The orifice is installed at one side of the second recirculation path. The pressure sensor is placed in the second recirculation path between the orifice and the high pressure regulator valve to sense the oil pressure. The electric motor operates the low pressure oil pump and high pressure oil pump at the same time by a transmission control unit based on information detected from the pressure sensor.
