摘要： A method is provided for controlling a gear shift from a forward gear to a reverse gear in a transmission arrangement, the method including the steps of: positioning a first locking mechanism and a first connecting mechanism at least in a partially engaged state for reducing a rotational speed of a planet carrier of a second planetary gear set; and positioning a second locking mechanism in an engaged state when a rotational speed of the planet carrier of the second planetary gear set is below a predetermined threshold limit.
