摘要： The present invention intends to provide a method of controlling speed change in a transmission provided with a torque converter having a direct-coupled clutch, capable of cushioning shock at the time of connecting the direct-coupled clutch and giving an operator an impression that the shock is occurring in the direction of speed increase. The method of controlling speed change comprises the steps of: automatically disconnecting the direct-coupled clutch (18) when a low speed stage is to be further shifted down; performing the shift-down operation; and, thereafter, automatically connecting the clutch (18) when a preset condition is satisfied.
