Abstract
An automatic transmission () of a vehicle having a central synchronization device () with at least one shift element () assigned to a transmission input shaft () and being a friction locking brake, an actuating device () driven by supplying energy, and at least one transmission region () disposed between the brake and a transmission output shaft (), an operative connection between the transmission input shaft and the transmission output shaft and different transmission ratios are producible over the at least one transmission region. The brake is transferable with the operative connection and the actuating device () into an operating state in which a transmission input shaft () interacting with the brake (), is held in a rotationally fixed manner by the brake (), wherein the brake () is held by the actuating () without any energy infeed.
