<p>The invention relates to a method for controlling an automatic transmission which is driven by an engine. A shift from a first transmission ratio to a second transmission ratio occurs in the form of a pull upshift or push downshift or a pull downshift or push upshift. A first coupling opens and a second coupling closes, and an electronic transmission control device controls the pressure characteristic of said first and said second coupling during the shifting operation by means of electromagnetic valves. This shifting operation is divided into various shifting phases, an engine intervention taking place in the load transfer (LT) of the gradient setting phase (SG), the sliding phase (SL), the gradient reduction phase (RG) and the closing phase (S), an engine torque and/or a characteristic value which determines the engine torque being transferred from the transmission control device to an engine control device of the engine.</p> |
