Abstract
An automatic transmission including an input shaft connected to a drive source; an output shaft connected to a driving wheel; a one-way clutch; friction engagement elements which establish speeds by changing a transmission path between the input shaft and the output shaft based on the application state of the friction engagement elements and application of the one-way clutch, one of the friction engagement elements being a brake that is applied when coasting in a take-off speed. The automatic transmission also includes a controller that determines whether it is possible to initially establish the take-off speed using the one-way clutch based on a predetermined condition, and, if not possible, then the controller establishes the take-off speed by applying the brake.
