ABSTRACT:
An automatic transmission for an automotive vehicle, having an input shaft connected to an engine of the vehicle via a primary clutch, an output shaft parallel to the input shaft and operatively connected to drive wheels of the vehicle, a plurality of pairs of gears for transmitting a drive force of the input shaft to the output shaft at different speed reduction ratios, respectively, at least one shift member for selectively placing the individual pairs of gears into an operative position, and an actuator device for automatically activating each shift member. The transmission includes a secondary clutch connected to the primary clutch by the input shaft, and disposed between the input and output shafts, an intermediate shaft disposed in a transmission line between the input and output shafts. The intermediate shaft is provided with one of the gears of each of at least one of the pairs of gears. The transmission further includes a one-way clutch disposed between the intermediate shaft and one of the input and output shafts. The one-way clutch permits power to be transmitted only in a direction from the input shaft toward the output shaft. Each pair of gears is placed into its operative position by the actuator device, with the secondary clutch being partially engaged while the primary clutch is held fully engaged.
