Abstract

A system for controlling power downshifts of a transmission includes a flare generation module, a flare control module, and a shift control module. The flare generation module generates turbine speed flare by decreasing pressure applied to an off-going clutch of the transmission. The flare control module decreases the turbine speed flare by increasing the pressure applied to the off-going clutch of the transmission. The shift control module increases a pressure applied to an on-coming clutch of the transmission when the turbine speed flare is less than a predetermined amount from a desired turbine speed flare.
