Which is better, AT transmission or DCT?

[AdrianaDella]

DCT is better. AT technology is more mature than DCT technology, with Japan's Aisin 6AT being the most widely used currently. DCT refers to dual-clutch transmission, which is divided into dry and wet types. Some high-end models generally use wet DCT because it has shorter shift times, matches the engine more perfectly, resulting in less shift jerkiness and better fuel efficiency. However, most models currently use dry DCT. Below are the advantages of AT and DCT: 1. Advantages of AT transmission: Mature technology, AT transmission is the most widely used and popular transmission on the market today. Traditional hydraulic automatic transmissions use a torque converter (or hydraulic coupler, multi-plate clutch, etc.), which can buffer engine power shocks and, combined with planetary gears, offers stable performance. It can also handle high torque. Even tanks have models equipped with AT transmissions. 2. Advantages of DCT transmission: Smooth shifting without the jerkiness common in general automatic transmissions. It is fuel-efficient and can efficiently utilize the kinetic energy generated by the engine, featuring advanced technology.
