Abstract
An automatic transmission has two countershafts, two clutches, an output shaft, two synchronizers, two input shafts adapted to be driven from the crankshaft of an engine through either of the two clutches and a one-way clutch that connects the first gear to the output shaft. The overrunning clutch is continuously driven but is easily overrun when higher gear ratios than the first ratio are selected. Changes of gear ratio result upon alternate engagement and disengagement of the friction clutches. Synchronizer clutches engage the next higher or lower speed ratio than the ratio in which the transmission instantaneously operates.
