Abstract

An automotive transmission includes an input shaft coupled to a torque converter or a clutch, an output shaft disposed parallel to the input shaft for driving a differential and transmission gear trains disposed between the input and output shafts. The first and second countershafts are disposed between the input and output shafts with an auxiliary transmission gear train connecting the input shaft and the first countershaft. The first and second countershafts are connected by normally meshing gears. A main transmission gear train with multiple gear ratios connects the second countershaft to the output shaft. A portion of the main transmission gear train is positioned adjacent the torque converter or the clutch to produce a compact arrangement.
