ABSTRACT:
A method and apparatus for cycling a neutral switch of an automated mechanical transmission includes software which, either independently or by operator command through a shift actuator having side-to-side motion capability and sensors, controls a select piston and cylinder assembly to provide shift rail motion along a transverse axis of the transmission which simulates operator commanded motion of a shift rail of a conventional (manual) transmission as the operator checks for neutral. Such activity may release a malfunctioning neutral switch thereby providing a proper neutral indication to associated transmission and engine components to, for example, permit starting of the engine.
