What is a Dual-Clutch Transmission?
A dual-clutch transmission is one approach to an automatic transmission. Think of it as a manual transmission controlled by a computer, but instead of one clutch, it has two. One clutch controls the even gears, while the other controls the odd ones. Dual-clutch transmissions are designed to shift between gears faster and be more fuel
