Reporters were invited to Eaton Corp.'s 600-plus acre Marshall Proving Grounds in Michigan to put its new Procision Class 6-7 dual clutch truck transmisison through its paces -- taking a variety of medium-duty models up and down steep inclines to try out the gearbox's "Hill Helper" and "Auto Grade Braking" features, as well as acceleration tests on the facility's banked oval track.
