Last update: 04 Sep. 2023Valeo Automotive Wet Clutches
The Double Wet Clutch (DWC) is a type of automatic multi-speed vehicle transmission system, that uses two separate wet clutches. The principle of such a transmission is to be able to switch gears without feeling the change. It is seamless gear shifting. Valeo is also developing Triple Wet Clutch (TWC).
