ABSTRACT:
A compound transmission comprising a main section and an auxiliary section is disclosed. The auxiliary section includes an auxiliary drive gear rotationally fixed to a mainshaft, an intermediate shaft having a reduction gear rotatably mounted thereon, and an output shaft having a splitter gear rotatably mounted thereon. Each of the auxiliary section gears is engaged with a corresponding auxiliary countershaft gear. A range clutch rotatable with the intermediate shaft selectively clutches the auxiliary drive gear or the reduction gear to the intermediate shaft, and a splitter clutch rotatable with the output shaft selectively clutches the intermediate shaft or the splitter gear to the output shaft. One of the four main section forward gears may be clutched in from either of two sides to give a nine forward speed compound transmission which uses a standard 5-speed shift pattern.
