A drivetrain system includes a controller that is programmed to, in a presence of a request for increased drivetrain torque that results in reversal of drivetrain torque direction, command an increase in drivetrain torque at a reduced rate while a value that is based on drivetrain speed difference remains within a predetermined range absent a braking torque request exceeding a threshold. The controller is further programmed to command the increase at an accelerated rate upon the braking torque request exceeding the threshold.
