Abstract
A compound transmission (10) comprising a main transmission section (12) connected in series with a range type multiple speed auxiliary section (14) having at least two selectable range type ratios, and a shift control unit (56) therefor, is provided. The shift control includes a resilient range interlock structure (178, 190) for inhibiting main section shifts from neutral during a range shift transient.
