VIDEO: How dual clutch gearboxes work

Dual clutch transmissions are all the rage these days because they combine the mechanical efficiency of a manual transmission with the ability of automatic transmissions to self-shift. Volkswagen was the first to introduce them to production cars under the DSG name a few years ago. Now they are starting to appear in vehicles from other manufacturers such as Volvo, Ford and Mitsubishi. Earlier this year, Chrysler announced they were building a joint venture transmission plant to build DCTs with Getrag. Volkswagen produced a video that explains some of the history of the DCT and how it works. Watch it after the jump.
