Abstract

A multi-speed transmission includes a first input shaft, a second input shaft, a first friction engagement mechanism, a second friction engagement mechanism, a first synchromesh mechanism, a second synchromesh mechanism, and a third friction engagement mechanism. A differential mechanism includes a first rotational element, a second rotational element, and a third rotational element. The first rotational element is coupled to a first countershaft. The second rotational element is coupled to a second countershaft. The third rotational element is coupled to an output member. A third synchromesh mechanism is capable of coupling a driving gear of a first gear train to the first input shaft or is capable of coupling a driven gear of the first gear train to the output member so as to enable power to be transferred between the first input shaft and the output member using the first gear train.
