ABSTRACT:
An automatic transmission for an automotive vehicle that transmits torque from an engine crankshaft to an outlet shaft includes a first clutch whose engagement driveably connects the engine directly to the output shaft and a second clutch whose engagement connects the engine to a countershaft on which a gear wheel having multiple pinions is formed. The output shaft has multiple forward drive output gears and a reverse output gear journalled on its outer surface. The countershaft has a forward drive pinion in continuous meshing engagement with a forward drive output gear, which is selectively connected to the output shaft by a synchronizer or coupler. A reverse idler gear wheel is in continuous engagement with the forward drive output pinion and with a reverse drive output gear that is connected to the output shaft by the synchronizer. A second synchronizer or coupler driveably connects selected forward drive gears to the output shaft.
