ABSTRACT:
A compound transmission arranged for conversion between a first configuration without overdrive ratios and a second configuration for which multiple, additional overdrive ratios are provided disables engagement/disengagement of a splitter gear in the first configuration while allowing selective engagement of the splitter gear in the second configuration. The transmission includes an auxiliary transmission section having a splitter gear, a splitter/range gear, and a range gear. A range clutch is provided for selectively connecting either the splitter/range gear or the range gear to the output shaft, and a splitter clutch is provided for selectively connecting either the splitter gear or the splitter/range gear to the output shaft. A range control and splitter control are provided for positioning the range clutch and the splitter clutch, respectively. Without requiring significant disassembly and reassembly of the auxiliary transmission section, the splitter control may be converted from a first configuration in which engagement of the splitter clutch with the splitter gear is disabled, to a second configuration in which engagement of the splitter clutch with the splitter gear is enabled thereby providing multiple, additional overdrive ratios.
