Abstract
An auxiliary transmission shift control system which combines the pressurized air supply lines for the range and splitter control switches mounted on the gear range selector lever in the vehicle cab and, therefore, eliminates one pressurized supply line. The interlock function (preventing shifting the splitter ON while in LOW range) is accomplished by preventing depressurization of the OFF side of the splitter cylinder if the range cylinder is in LOW position. Depressurization is prevented by pressurizing the OFF side of the splitter cylinder via a passageway connecting with the LOW side of the range cylinder.
