In a multi-regime continuously variable ratio transmission system, the clutch (H) of a new regime is applied substantially instantaneously in a synchronous mode of the transmission to allow the clutch engagement to be based on the actual, rather than the predicted, ratio of the transmission. The transmission system is under the control of a control system applying clutch apply pressure and controlling the setting of the variator forming part of the transmission system, the control of the clutch apply pressure being carried out independently of the control of the variator such that the settings of the variator are unaffected by the variations in the clutch apply pressures.
