A method and arrangement for controlling a continuously variable transmission with improved response time, the continuously variable transmission having a first pulley engagable with an engine and having a second pulley drivingly connected to the first pulley by a belt. The first and second pulleys each have a fixed sheave and a movable sheave, a position of the movable sheaves defining a transmission ratio. The method and arrangement provides for disengaging the engine from the first pulley and increasing the speed of the engine to a target speed, reducing pressure to the movable sheave of the first pulley to a low value, increasing pressure to the movable sheave of the second pulley causing it to rapidly move to a new position thereby changing the transmission ratio to a target transmission ratio, increasing the pressure to the first pulley, and reengaging the engine to the first pulley. |
