Abstract
Change-speed transmission providing multiple forward speeds and at least one reverse speed. An output shaft of the transmission carries a first speed pinion or gear that is rigid with a hollow shaft that carries, in turn, a gear or pinion of the reverse gear train disposed upstream of other forward speed gears or pinions. The reverse gear carries a dog that is separated from a dog carried by the closest forward speed gear by a dog and synchromesh unit. A layshaft mechanism is positioned parallel to the output shaft to increase the number of gear ratios provided by the transmission.
