ABSTRACT:
A fluid coupling for an automatic transmission includes an input element, an output element and a lockup clutch and is connected to a transmission mechanism. The lockup clutch can engage and disengage to operatively connect and disconnect the input element and the output element with and from each other. Further the lockup clutch can engage in slipping engagement to connect the input element and the output element in such a way as to allow the input element and the output element to rotate relative to each other to some extent. A control system causes the lockup clutch to engage in slipping engagement with a substantially fixed engaging force when the transmission mechanism upshifts while the lockup clutch is in slipping engagement, and to disengage when the transmission mechanism downshifts while the lockup clutch is in slipping engagement.
