Abstract
A valve body assembly for an automatic transmission formed by superimposing and clamping a torque converter casing, a first separation plate, a main valve body, a second separation plate, a second valve body, a third separation plate and a servo body. Pairs of first separation plates and pairs of second separation plates are provided, one pair for 7-position types of automatic transmissions and another pair for 6-position types of automatic transmissions and are, respectively, selected, used and assembled between the converter casing and main valve body and the main valve body and second valve body depending upon whether a 7-position type of transmission or a 6-position type of transmission is being assembled. Thus, general purpose properties are provided to the valve body assemblies used in hydraulic pressure control systems for 7-position type and 6-position type automatic transmissions for vehicles and the like.
