ABSTRACT:
A slip control system for an automatic transmission includes a fluid coupling including a release side oil chamber, an apply side oil chamber and a lockup clutch unit that is applied and released on an basis of the oil pressure that is fed to at least one of the release side oil chamber and the apply side oil chamber; an oil pressure generating unit for generating the oil pressure; a vehicular running state detecting unit for a detecting vehicular running state; an electronic control unit for determining whether a slip control is to be made, on the basis of a determination upon whether the present vehicular running state, as detected by the vehicular running state detecting unit, belongs to a predetermined slip control region; and an oil pressure regulating unit for regulating the oil pressure in response to a signal coming from the electronic control unit, to make the slip control by sliding the lockup clutch unit. The electronic control unit determines the state of a heat, as generated according to the slip control; and changes the slip control region on the basis of the heat state.
