It is divided into volume and dynamic two. The latter is often referred to simply as a hydrodynamic transmission, which transfers energy primarily through the dynamics of the working medium. In the car on the form of torque converter and hydraulic coupling. Coupling no twist, Hyundai Motor has rarely used.
