description A transmission includes at least one shift element for which both the apply pressure and the release pressure are actively controlled. A controller adjusts the torque capacity of the shift element by varying the apply pressure and the release pressure in a coordinated fashion. During particular events, such as a shift event with the shift element as oncoming element or holding element, both the apply pressure and the release pressure are monotonically increased, mitigating the effect of hysteresis.
