A control system for auxiliary section range and/or splitter control includes a direct ported control valve assembly having a spool disposed within a bore of a cover housing, the spool having a differential area to bias the valve and two sealing members radially biased by a spring to direct pressurized air or hydraulic fluid to an appropriate side of a piston to effect the splitter and/or range shift of the transmission. The control valve assembly includes components, such as the valve spool, which may be used in various transmission applications in addition to components, such as the pilot cap and seal plate, which may be selected to control the logic (normally open or normally closed) of the valve assembly and the apply rate of the range and/or splitter cylinder depending upon the particular application. A filter/regulator is mounted to the valve cover assembly to provide direct porting of the pressurized fluid supply to eliminate connecting hoses.
