To understand how a dual-clutch automated manual transmission works, let’s refresh how a regular manual transmission operates: you press the clutch, engage the first gear, then release the clutch; the steps are repeated with every shift. A dual-clutch automated manual transmission has two wet computer-controlled clutches (wet clutch means the friction plates are immersed in transmission fluid). One clutch controls odd gears (1,3,5); the other clutch controls even gears (2,4,6). When the car starts in the first gear, the second gear is already pre-shifted and as soon as the car reaches the speed suitable for the second gear, the odd-gear clutch disengages the first gear and almost simultaneously the even-gear clutch engages the second gear. Similarly, with the next 2-3 gear shift and so on. All this is done to minimize time and torque loss between gear shifting. According to Nissan, in the 2013 Nissan GT-R it takes only 0.15 seconds to change gears when in “R” mode.
