A firing module determines a target number of activated cylinders of an engine based on a torque request and a present gear ratio of a transmission. A combination identification module, based on the torque request, identifies a combination including a possible number of activated cylinders and a possible transmission gear ratio, wherein at least one of: the possible number of activated cylinders is different than the target number of activated cylinders; and the possible transmission gear ratio is different than the present gear ratio of the transmission. A transitioning module, when a second fuel consumption for the possible number of activated cylinders and the possible transmission gear ratio is less than a first fuel consumption for the target number of activated cylinders and the present gear ratio, selectively: transitions the target number of activated cylinders to the possible number of activated cylinders; and transitions a target gear ratio of the transmission to the possible transmission gear ratio. An activation/deactivation module controls cylinder activation and deactivation based on the target number of activated cylinders.
