PROBLEM TO BE SOLVED: To respond to start acceleration request in a select operation from a parking range to a travelling range while achieving a simpler mechanism by actuator sharing. ! SOLUTION: An automatic transmission for a vehicle includes an engagement clutch 8c, a friction clutch 9c, a park gear 17 and a parking pole 18. In this automatic transmission for a vehicle, a first electric actuator 41 is provided for operating a coupling sleeve 8f and the parking pole 18 together. An actuator interlocking mechanism 61 is provided between the first electric actuator 41, the coupling sleeve 8f and the parking pole 18. In the actuator interlocking mechanism 61, a range position selected when the first electric actuator 41 is operated in one direction is set to be in a parking range position P by engagement fastening of a park mechanism, in a low speed stage range position L (1st) by synchronous fastening of the engagement clutch 8c and in a high speed stage rage position H (2nd) by friction fastening of the |
