PROBLEM TO BE SOLVED: To provide a transmission for an automatic shift that prevents a fuel consumption ratio from worsening by selecting a composition with fewer brakes as a tigtening element. SOLUTION: There are provided, a single pining type first planetary gear, a single pinion type second planetary gear, a single pinion type third planetary gear, an input member connected to a first gear, an output member connected to a second carrier, a first connection member for unitedly connecting a second sun gear and a third sun gear, a second connection member for unitedly connecting the second carrier and a third ring gear, a first clutch for selectively cutting or connecting a first carrier and a second ring gear, a second clutch for selectively cutting or connecting the first carrier and the first connection member, a third clutch for selectively cutting or connecting a third carrier and the second connection member, a fourth clutch for selectively cutting or connecting the input member and the third carrier, and a first brake for selectively stopping the rotation of the third carrier.
