Abstract
A high-capacity compound transmission (200/400) of lighter weight and/or shorter axial length than comparable prior art transmissions is provided. In one embodiment, the compound transmission of the present invention utilizes main and auxiliary section countershafts (324, 362) which are coaxial and define a countershaft assembly supported solely by bearings in the transmission housing (214) forward and rearward end walls (214A, 214B) and by intermediate bearing means (324B) carried by a partial intermediate housing wall (214C) axially aligned with the axial travel space (380) of a mainshaft clutch (64). The mainshaft (346) is supported solely at the forward and rearward ends thereof on or by the rearward end of the input shaft (16) and forward end of the output shaft (358).
