Abstract
A dual pressure pump system for a transmission includes a dual pressure pump having a first pump outlet and a second pump outlet, and a pressure regulator valve defining a first chamber in fluid communication with the first pump outlet and a second chamber in fluid communication with the second pump outlet. The pressure regulator valve is configured to selectively connect the first chamber with a first pressure line operating at a first greater-than-zero pressure and to selectively connect the second chamber to a second pressure line operating at a second greater-than-zero pressure.
