Patent ID: 8079935

Claim:
A shift control device for an automatic transmission, which executes a shift from a current gear position to a target gear position by selectively engaging and disengaging a plurality of friction elements, comprising: a thermal load prediction unit which predicts a thermal load state of the friction element upon completion of the shift from a current thermal load state of the friction element; and a shift control unit which, when the thermal load state upon shift completion predicted by the thermal load prediction unit corresponds to a predetermined state, either performs the shift in a modified shift mode in which a heat generation amount of the friction element is smaller than the heat generation amount of the friction element when the predetermined state is not established, or prohibits the shift, wherein the predetermined state is set at a different state in a case where the shift is an upshift and in a case where the shift is a downshift, and is set on the basis of a gradient of a traveling road.
