Abstract

A transmission mechanism with a pair of selectively engageable clutch systems has an upstream gear ratio and a downstream gear ratio that combine to provide an effective gear ratio. A different clutch drive member is associated with an input side of each of the pair of clutch systems. The clutch drive members are driven for rotation by an engine input member. The upstream gear ratio is determined by the gear ratio between the engine input member and one of the clutch drive members. Output sides of each of the clutch systems drive an associated one of a pair of non-coaxial layshafts. Pinions are located on and selectively driven by the layshafts. A countershaft is spaced from both of the layshafts, and has a plurality of gears. Each of the gears is driven for rotation by one of the pinions of the layshafts. The downstream gear ratio is determined by the gear ratio between the selected pinion and the intermeshed gear.
