Abstract
A manual transmission has a main gear box and an auxiliary box with an input shaft extending along an axis from a first end that extends into the auxiliary box for transmitting power to the auxiliary box. The auxiliary box has an output shaft having a second end adjacent the input shaft and coaxial with the axis for transmitting power out of the auxiliary box. A first gear is supported by the input shaft at the first end, and a second and third gear are supported by the output shaft. At least one countershaft having fourth, fifth, and sixth gears affixed to a shaft engages the first, second, and third gears, respectively. A synchronizer and a clutch collar are supported by the output shaft for engaging one of the first, second, and third gears. The arrangement eliminates an intermediate shaft that was required in the prior art.
