To many drivers, the choice between manual and automatic transmission comes down to geographical location or personal preference. Modern dual-clutch offers the best of both worlds.

A dual-clutch transmission (DCT) sometimes referred to as a twin-clutch transmission or double-clutch transmission is an automated manual transmission in automobiles, closely related to a manual transmission.


It uses two separate clutchesfor odd and even gear sets. It can fundamentally be described as two separate manual transmissions with their respective clutches contained within one housing, and working as one unit.
