The valve body contains many of the hydraulic valves, such as the pressure regulator, shift valves, manual valve, and others used in an automatic transmission. The valve body bolts to the bottom of the transmission case and is housed in the transmission pan. A filter or screen is attached to the bottom of the valve body. Passages in the valve body route fluid from the pump to the valves and then into the transmission case. Passages in the transmission case carry fluid to other hydraulic components. To get an idea of how complicated the hydraulic system really is, a schematic view of an actual hydraulic system for an automatic transmission is shown is figure 4-41.
