Automatic transmissions are mainly divided into five types: Automatic Transmission (AT), Automated Mechanical Transmission (AMT), Dual-Clutch Transmission (DCT/DSG), Continuously Variable Transmission (CVT), and Sequential Transmission. AT achieves smooth gear shifting through a torque converter and planetary gear set, featuring mature technology and high reliability, and is commonly found in mid-to-high-end models. AMT realizes automatic gear shifting by adding an electronic control module to a manual transmission, with a simple structure and low cost, but has noticeable shift jerkiness. DCT uses two clutches working alternately, offering fast shifting speed and high transmission efficiency, making it suitable for performance-oriented models. CVT achieves stepless speed variation through a steel belt and cone pulleys, with linear power output and excellent fuel economy, widely used in economy cars. Each of these transmissions has distinct characteristics. The selection should be based on comprehensive consideration of driving habits and vehicle positioning.
