変速制御装置。[Claims for Utility Model Registration] A first transmission that automatically shifts gears to at least two or more gears and a second gearbox that automatically shifts gears to at least two or more gears are arranged in tandem, and these first and second transmissions are arranged in tandem. A large number of gears can be obtained by shifting the transmission simultaneously or alternately, and these first and second
In a vehicle automatic transmission in which a small number of gears is achieved by mainly shifting one of the transmissions, a load change rate detection means for detecting a rate of change in engine load; The load change rate detected by the rate detection means is used as at least one control condition, and a gear speed selection means is provided for selecting a shift in a higher gear position when the load change rate is large and a gear shift in a lower gear position when the load change rate is small. A speed change control device for an automatic transmission for a vehicle, characterized by:
