A method for controlling a powertrain is disclosed. The powertrain includes a work arrangement, an engine for providing power to the work arrangement, and a transmission for transmitting power from the engine to the work arrangement. The method includes determining an efficient speed range of the transmission, determining at least one parameter indicative of a speed of the transmission, determining if the speed corresponds to the efficient speed range of the transmission, and adjusting the engine output in response to determining if the speed corresponds to the efficient speed range of the transmission.
