Abstract
A method and system for controlling gear ratio changes of a transmission operating in a powertrain with an internal combustion engine controlled by an engine throttle and having a device, such as traction assist system, that alters engine torque from that corresponding to the position of the throttle. The control substitutes a synthetic throttle position for actual throttle position during a traction assist event. Gearshifts occur with reference to a schedule relating the desired gear, vehicle speed, and synthetic throttle position.
