Abstract
A transmission control module comprises an actuation module and a flare control module. The actuation module controls actuation of a friction device used in shifting from a first transmission ratio to a second transmission ratio. The transmission ratio is based on an input speed of a transmission divided by an output speed of the transmission. The first transmission ratio is greater than the second transmission ratio. The flare control module selectively generates an engine torque reduction request when a measured transmission ratio is greater than a threshold during a shift from the first transmission ratio to the second transmission ratio.
