Abstract
A method for controlling a transmission system mounted on such as a traveling machine or a construction machine, the transmission system having a two-stage clutch configuration in which a speed is selected through a combination of a plurality of sub transmission clutches and a plurality of main transmission clutches. At the time of speed change, engagement is started beginning with the main transmission clutch side, and the engagement of the sub transmission clutch is commenced upon completion of the filling of the oil in the main transmission clutch, thereby reducing the two speed-change shocks, including a reverse shock, which are conventionally experienced.
