Zusammenfassung:	A method of controlling thermal loading in a multi-speed dual-clutch transmission (DCT) that is paired with an internal combustion engine in a vehicle is provided. The method includes detecting operation of the vehicle and ascertaining a degree of thermal loading on the DCT. The method also includes selecting a remedial action corresponding to the ascertained degree of thermal loading. Additionally, the method includes activating the selected remedial action such that the thermal loading on the DCT is reduced. A vehicle having a DCT, an internal combustion engine, and a controller configured to control thermal loading in the DCT is also disclosed.
