Abstract
An auxiliary box for a heavy vehicle transmission includes a shift cylinder wherein fluid drives a piston in a first direction, and a spring drives a shift fork in an opposed second direction. If fluid is supplied to drive the piston in the first direction, a first gear is engaged in the auxiliary box, and if fluid is relieved the spring drives a shift fork to engage a second piston. The invention thus eliminates some of the fluid controls and components in the prior art.
