Beschreibung
Zusammenfassung:	A pressure regulator valve assembly for an automatic transmission includes a valve body, a valve chamber within the valve body, a valve piston disposed within the valve chamber, the valve piston having a valve channel, and a check valve disposed within the valve channel, the check valve is operable to permit fluid flow in the valve channel in a first direction and substantially prevent fluid flow in the valve channel in a second direction opposite to the first direction. An automatic transmission may include the pressure regulator valve assembly between a hydraulic pump and a torque converter, the pressure regulator valve assembly configured to control fluid flow between the hydraulic pump and the torque converter.
