How Dual-clutch Transmissions Work?

The Volkswagen's Dual-clutch Transmission is called Direct Shift Gearbox (DSG).

Here is the function of DSG which I found in the Golf GTI catalog:

DSG is a manual gearbox in which the gearshifts are controlled

electronically. What makes the DSG unique is that it has 2

separate gear sets operated by 2 wet multi-plate clutches. The

benefit of 2 gear sets and 2 multi-plate wet clutches is that one

gear set and clutch is engaged driving the vehicle with the

second clutch having already pre-selected the next gear

awaiting for power to be transferred. As the next gear has already

been pre-selected prior to power being applied, the gear change

only takes 3–4 100ths of a second. There is virtually no

interruption to power, traction or acceleration.
