The invention concerns a simple mechanical arrangement for controlling a multi- regime continuously variable transmission. The transmission in questi on comprises a variator (10) and a gearing arrangement including a low regim e clutch (CL) and a high regime clutch (CH). Engaging the low regime clutch places the transmission in the low regime. Engaging the high regime clutch p laces it in the high regime. The control system comprises a control part (su ch as a lever) which is movable by the user along a control path from a low ratio end to a high ratio end. The position of the control part dictates var iator ratio and transmission ratio. The system further incorporates a low re gime clutch control device which engages the low regime clutch when the cont rol part is between the low ratio end of its path and a low clutch transitio n point, and which releases the low regime clutch when the control part is b etween the low clutch transition point and the high ratio end of its path. I t additionally incorporates a high regime clutch control which releases the high regime clutch when the control part is between the low ratio end of its path and a high clutch transition point, and which engages the high regime clutch when the control part is between the high clutch transition point and the high ratio end of its path. In this way, amechanical arrangement can be provided which manages both transmission ratio and the clutch changes requi red upon regime change.
