Abstract
A transmission associated with a powertrain receives torque from a power source and includes a plurality of gear sets that can be selectively engaged and released. To shift gear sets, a shifting process conducted by an electronic controller may estimate a torque assist capacity of the power source to provide or accommodate changes in torque during the gear shift. If the torque assist capacity is less than a gear shift torque value, the shifting process prevents or ignores the gear shift.
