Claim 8:
9. A vehicle comprising:
an engine configured to generate power;
a transmission (i) configured to transfer power from the engine to at least one drive wheel to propel the vehicle and (ii) having a plurality of clutches configured to shift the transmission between a plurality of gear ratios;
an accelerator pedal configured to generate a command corresponding to a desired engine torque in response to depression of the accelerator pedal; and
a controller programmed to,
in response to a command to shift the transmission, reduce a torque of the engine from the desired engine torque to a reduced value based on a flare at an input to the transmission during the shift,
in response to the reduced value exceeding a threshold, retard an engine spark and maintain operation of all cylinders of the engine to reduce the torque of the engine during the shift, and
in response to the reduced value being less than the threshold, retard the engine spark and shutdown at least one cylinder of the engine to reduce the torque of the engine during the shift.
