The invention relates to valve system configurations for an active warm-up (AWU) system for an automobile to improve warm-up conditions without delaying cabin warm-up or defrost times. More specifically, the invention relates to a system for heating/cooling transmission fluid of an automobile by controlling the source of the heat exchange fluid for transferring heat to/from the transmission fluid during different start-up conditions using a series of various valves arranged in series intermediate a first heat exchanger associated with cabin warm-up/defrost of the passenger compartment and a second heat exchanger for transferring heat to/from the transmission fluid.
