What are the types of car transmissions?

The classification of transmissions is as follows: 1. Manual Transmission; Also known as manual gear, it requires manually shifting the gear lever to change the gear engagement position inside the transmission, altering the gear ratio to achieve speed variation. The manual transmission (clutch and gear lever) is the most basic and effective shifting method. 2. Manual Transmission with Automatic Clutch and Automatic Shifting Device (AMT); The hydraulic device on the AMT transmission operates the clutch and shift fork based on computer commands or gear lever commands, essentially equipping the driver with a mechanical left foot and right hand. 3. Automatic Transmission (AT): Utilizes planetary gear mechanisms for shifting, automatically changing gears based on throttle pedal position and vehicle speed. The driver only needs to control the speed via the accelerator pedal. It replaces the traditional contact clutch with a hydraulic torque converter, with shifting actions performed by hydraulic mechanisms. 4. Dual-Clutch Transmission (DSG), also known as Direct-Shift Gearbox: Unlike conventional transmission systems, the DSG is based on manual transmission rather than automatic. Manual transmissions are much more efficient than automatic ones, and the DSG combines the flexibility of manual with the comfort of automatic, while also providing uninterrupted power output. 5. CVT (Continuously Variable Transmission): A transmission that adjusts the gear ratio via hydraulic control of conical pulleys to achieve 'shifting'. It consists of two sets of variable pulleys and a drive belt, making it simpler and more compact than traditional automatic transmissions. Additionally, it can freely change the gear ratio, enabling seamless speed variation without the 'jerk' feeling typical of traditional gear shifts.
I used to drive a manual transmission car and found it quite enjoyable. Nowadays, there are many types of transmissions on the market: Manual Transmission (MT) is the favorite among experienced drivers, requiring you to press the clutch and shift gears yourself; Automatic Transmission (AT) is the most common, where the computer shifts gears smoothly for you, making it especially convenient in traffic jams; CVT Transmission has become popular in recent years, using a steel belt for transmission which is very fuel-efficient and eliminates jerking during acceleration; Dual-Clutch Transmission (DCT) has two clutches for extremely fast gear shifts and is commonly found in sports cars; AMT Automated Manual Transmission is relatively rare, essentially a manual transmission controlled by a computer, with a simple structure and cheap repairs. Many cars now also offer hybrid options, such as Tiptronic, which is an AT with a manual mode. Choosing a transmission depends on your needs—if you enjoy driving dynamics, go for a manual; if you prefer convenience, opt for AT or CVT.
