    Abstract: A system and method for decreasing the time required to complete a ratio change in an electronically enhanced powertrain system include independently controlling at least one engine-side retarding device and at least one transmission-side retarding device. The retarding devices are selectively actuated to increase the decay rate of the engine speed and/or transmission input shaft speed during an upshift. Engine-side retarding devices may include an engine brake or operation of various engine accessories to increase engine loading. Transmission-side retarding devices may include input shaft brake or driveline retarder.
