A method and system of determining the instant gradient of a road, taking into account positive and negative drive torque, may be used to select one of a plurality of shift maps for a vehicle automatic transmission. The invention takes into account vehicle retardation due to braking, and permits consistent adoption of a shift map appropriate to the instant gradient.
