Abstract
A transmission and a method for loading an engine in a vehicle. The transmission includes a gear set, an input shaft coupled to the gear set, and a plurality of friction elements coupled to the gear set. The transmission also includes a control system to direct a subset of the plurality of friction elements to engage the gear set to stall the input shaft thereby placing a load on the engine. The load causes additional heat that may be used to warm up the vehicle's passenger compartment and/or defrost the vehicle's windshield.
