Abstract
A unitized valve body for use in an automatic transmission includes a valve bore and an annulus. The valve bore is configured to receive a valve. The annulus is in fluid communication with the valve bore. The annulus defines an outer portion having an outer diameter and an innermost portion located at an interface between the valve bore and the valve. The outer portion having a first axial length and the innermost portion having a second axial length. The first axial length is greater than the second axial length.
