Abstract
A method for downshifting a vehicle having an automatic transmission is described. In one example, the method determines whether or not conditions are met for a power matching downshift. If conditions are met for a power matching downshift, output power of a powertrain propulsion torque source at an end of the power matching downshift is adjusted to an output power of the powertrain propulsion torque source at the beginning of the power matching downshift plus an offset power.
