Abstract
PURPOSE:To prevent the generation of speed change shock by enabling almost of all speed changes to achieved only by engagement or release of a single frictional engaging element. CONSTITUTION:In a connecting path of an input shaft IS and a carrier 25 of a double pinion type planet gear train 20, a connecting path of a sun gear 11 of a single pinion type planet gear train 10 and a case, a connecting path of a sun gear 21 of said gear train 20 and the case and a connecting path of a ring gear 13(24) of the single (and double) pinion type planet gear train 10(and 20) and the case are respectively disposed one-way clutches F1, F3, F4 and F2. As a result, speed change between first and second speed stages is achieved by the turning-off of clutch C4 and the turning-on of clutch C2, speed change between second and third speed stages by brake B3, speed change between third and fourth speed stages only by the turning-on of clutch C1 and speed change between fourth and fifth speed stages only by the turning-off of brake B4. Thus, speed change shocks due to the engagement or deviation of timing of a plurality of frictional engaging elements can be prevented.
