Continuously variable transmission and control method therefore

摘要

A transmission controller (12) reduces a hydraulic pressure of a release-side frictional engagement element (High clutch 33) which is to be released of a sub-transmission mechanism (30) and reduces this reduction amount as an input torque to the sub-transmission mechanism (30) increases at the time of starting a shift when a manual mode is selected, the input torque is positive and the sub-transmission mechanism (30) is to be shifted down.
