A method for controlling a powertrain system includes determining a current transmission operating range state and engine state, determining at least one potential transmission operating range state and engine state, providing at least one operator torque request, determining preferability factors associated with the current transmission operating range state and engine state, and potential transmission operating range states and engine states, wherein determining preferability factors associated with potential transmission operating range states includes assigning biasing costs to operator torque requests which reside within a pre-determined range of possible operator torque requests for at least two of the potential transmission operating range states, preferentially weighting the preferability factors for the current transmission operating range state and engine state, and selectively commanding changing the transmission operating range state and engine state based upon stheaid preferability factors and the operator torque request.
