Abstract
A control valve assembly (94) is provided for allowing manual and automatic splitter shifting in a compound splitter-type vehicular transmission system (92). The control valve assembly is interposed in series between a selectively pressurized and exhausted conduit (108) controlled by a manual selector valve (104) and a pilot conduit (110) controlling the operation of a splitter shift actuator (86). The control valve assembly is designed to fail in a position allowing fluid communication between the selectively pressurized and exhausted conduit and the pilot conduit.
