Abstract
A multispeed constant mesh gear transmission includes an input shaft together with first, second and third intermediate shafts arranged in a diamond or cruciform configuration together with an output shaft having an axis of rotation lying in a plane including the input shaft and the third intermediate shaft. In two different embodiments each of the three intermediate shafts include two multiplate fluid actuatable clutches shiftable under load. A plurality of gear trains selectively drive an output shaft at six different rotative speed ratios with respect to the input shaft in one direction of rotation of the output shaft and at three different speed ratios in the opposite or reverse direction of rotation of the output shaft. In one embodiment a total of six clutches and fourteen gears provide for the speed ratios and in a second embodiment a total of twelve gears and six clutches provide for the six forward and three reverse speed ratios.
