A control system for a power transmission (1) unit configured to shift an operating mode smoothly by manipulating engagement devices (CL1, CL2), and to simplify a structure of the power transmission unit (1). The control system is configured to reduce a speed difference between an axially stationary engagement element (20) and a reciprocatable engagement element (21) of a second engagement device (CL1) when shifting from a first continuously variable mode to a second continuously variable mode by engaging the second engagement device (CL1). After the second engagement device (CL1) has been engaged completely, a first engagement device (CL2) is disengaged.
