A hydraulic pressure supply system of an automatic transmission for a vehicle is disclosed. The hydraulic pressure supply system of an automatic transmission for a vehicle may supply a low hydraulic pressure generated at a low-pressure hydraulic pump to a low pressure portion through a low-pressure regulator valve, may supply a portion of the low hydraulic pressure to a high-pressure hydraulic pump, and may supply a high hydraulic pressure generated at the high-pressure hydraulic pump to a high pressure portion through a high-pressure regulator valve. |
