description The invention relates to a control system in a continuously variable transmission (1) that comprises a variator unit (30), a planetary gearing (20) with a forward drive clutch (26) and a torque converter (10) with a lock-up clutch (16), which control system includes a lock-up switch valve (V1) for engaging or disengaging the lock-up clutch (16) and a clutch engagement valve (V2) for engaging or disengaging the forward drive clutch (26). In accordance with the invention the control system includes a single electromagnetic actuator (S6) that directly or indirectly operates both the said lock-up switch valve (V1) and the said clutch engagement valve (V2).
