The computer-actuated selectors shift between gear sets, while the clutches switch between the two internal transmissions. One clutch connects to a hollow outer shaft that spins the gears in the even-numbered gears, while the other one bolts to a slender inner input shaft that spins inside the other one, and sends power to the “second” transmission with the odd-numbered gears.

“So it is quicker than a human being could shift a manual transmission.” “You’ve got a shaft that has your even-numbered gears, 2, 4, 6 and 8, and your odd gears, 1, 3, 5, 7, and you can be simultaneously disengaging one shaft while you are engaging another one,” he continued. Or, more accurately, the transmissions’ input shafts. The clutches are also mounted inline, behind the engine’s flywheel and connected to the transmission’s input shaft.

“A dual-clutch transmission is effectively two manual gearboxes that have clutches actuated by computers on a concentric shaft,” explained Ed Piatek, Corvette chief engineer. It needs two clutches because it is actually two separate transmissions, mounted in a straight line. But rather than a conventional automatic’s hydraulic torque converter spinning planetary gearsets, the DCT uses a conventional friction clutch spinning regular manual transmission gearsets.Ī DCT doesn’t have a clutch pedal, because the clutches are computer-controlled.

The DCT is an automated transmission, so it shifts gears by itself, or in response to clicks from steering wheel shift paddles, like a traditional automatic transmission. Why would a transmission need two clutches, anyway? And where’s the clutch pedal? Why do new sports cars like the Chevrolet Corvette, Ford Shelby Mustang GT500 and Ferrari SF90 Stradale use them instead of the familiar H-pattern manual-shift transmissions? New cars are commonly built with dual-clutch transmissions (DCT), but the idea of such a thing can seem puzzling.
