An auxiliary transmission section for a compound transmission includes an auxiliary countershaft assembly including a auxiliary countershaft, a first auxiliary countershaft gear fixed for rotation on the auxiliary countershaft and constantly meshed with an output shaft splitter gear, and a second auxiliary countershaft gear surrounding the auxiliary countershaft and constantly meshed with an intermediate shaft output gear for coupling either the intermediate shaft or main countershaft of a main transmission section thereby allowing fewer gears to be utilized to achieve a desired number of speed ratios. |
