    • PROBLEM TO BE SOLVED: To provide an automatic transmission for a vehicle for enjoying convenience of an automatic transmission while almost maintaining excellent efficiency of a manual transmission. SOLUTION: The automatic transmission for the vehicle comprises a first shift part which outputs three intermediate speeds of constant speed, increased speed and reverse rotation speed by utilizing rotating power input through a first and second variable input path, and a second shift part which includes a first, second third and fourth gears for realizing a first, second third and fourth gear ratios, respectively, and which shifts each intermediate speed transmitted from the first shift part to four final speeds to be output.
