What does the transmission mainly refer to?

Transmission mainly refers to the gearbox of a car, which is divided into manual and automatic types. The manual transmission is mainly composed of gears and shafts, achieving speed and torque variation through different gear combinations. The automatic transmission (AT) consists of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic power transmission and gear combinations. The transmission is a mechanism used to change the speed and torque from the engine, capable of fixing or changing the transmission ratio between the output shaft and input shaft in steps, also known as the gearbox. The transmission is composed of a transmission mechanism and a control mechanism, with some cars also having a power take-off mechanism. Most transmission mechanisms use ordinary gear transmission, while some use planetary gear transmission. Ordinary gear transmission mechanisms generally use sliding gears and synchronizers.
