A method for controlling regenerative braking in a hybrid electric powertrain includes using an e-pump to supply fluid to a transmission provided an indication that a torque converter clutch disengagement will occur under current powertrain operating conditions is present, and discontinuing use of the e-pump and using a mechanical pump to supply fluid to the transmission provided the indication that a torque converter clutch disengagement will occur under current powertrain operating conditions is absent.
