摘要： PROBLEM TO BE SOLVED: To provide an automatic transmission which can add a speed change stage containing a direct connection stage on the high speed stage side so as to make a gear ratio closer, derive the optimum performance of an engine in the high speed range of the vehicle speed, and obtain a gear ratio of 7th stage forward or higher which provides high effectiveness and small vehicle speed change at gear change to offer excellent feeling. SOLUTION: The automatic transmission is provided with a reduction gear device generating decelerated revolution whose number of revolution is less than that of an input shaft. A decelerated revolution output member is changed to be at decelerated revolution status or free revolution status by revolution status switching means. Decelerated revolution of the decelerated revolution output member is selectively transmitted to the fourth and the first elements of a dual planetary gear train for speed change through the first and third control clutches. While revolution of the input shaft is transmitted to the second element through the second control clutch, the revolutions of the first and the second elements are selectively regulated with the second control brake to connect the third element to the output shaft.
