A synchronizer-controlled transmission has a plurality of input shafts, which are selectively connectible with a transmission input shaft, at least one countershaft, which rotatably supports a plurality of ratio gears, and an output shaft. A plurality of synchronizers is disposed along the countershaft and at least one input shaft to provide power transmission connections between the countershaft and the ratio gears disposed thereon. At least one ratio is established through direct connection between at least one input shaft and the output shaft.
