What are the 4 types of transmissions?

Automotive transmissions are mainly divided into four types: Manual Transmission (MT), Automatic Transmission (AT), Continuously Variable Transmission (CVT), and Dual-Clutch Transmission (DCT). Manual Transmission directly controls gear engagement through the clutch pedal and gear shift lever. It has the advantages of high transmission efficiency and low maintenance costs, making it suitable for car owners who pursue a sense of driving control. Automatic Transmission uses a torque converter and planetary gear set to achieve automatic gear shifting. It is easy to operate but has a complex structure and high maintenance costs, and is commonly found in mid-to-high-end models. Continuously Variable Transmission achieves stepless speed variation through pulleys and a steel belt. It offers smooth gear shifting and good fuel economy, but has limited torque capacity, so it is mostly used in small and medium-displacement models. Dual-Clutch Transmission operates with two sets of clutches working alternately. It combines the high efficiency of manual transmission with the convenience of automatic transmission, featuring fast shifting speed and low fuel consumption, but may produce slight jerking at low speeds. Each of these transmission types has its own characteristics. When making a choice, it is necessary to consider driving habits, budget, and vehicle positioning. For example, those who prioritize economy may consider CVT, while performance car enthusiasts might prefer DCT or MT. It should be noted that regularly changing the specified type of transmission fluid (such as ATF or CVT-specific fluid) is crucial for extending the service life. Maintenance is recommended every 40,000 to 60,000 kilometers.
