Systems and methods for improving transmission shifting of a hybrid vehicle are presented. In one example, output torque of an electric machine is adjusted in response to a downshift of a fixed step ratio transmission during regenerative braking. The output torque of the electric machine may be adjusted in response to a phase of the transmission shift.
