Abstract
An automatic transmission in which first to third clutches which can couple an input shaft to a first element of a first multiple planetary gear set and second and fourth elements of the second multiple planetary gear set, respectively, are arranged on a front side of the first multiple planetary gear set. Thus, it is possible to prevent a situation in which disengaging of the third clutch in the first speed causes the fourth element of the first multiple planetary gear set to rotate in reverse and generate a large relative rotation with the first element.
