Manual transmission: The so-called manual transmission refers to a mechanical transmission that manually operates the shift lever to switch forward gears. During the shifting process, the clutch is also controlled by a foot pedal. This is the most primitive but also the lowest manufacturing cost automotive gearbox.

自動變速箱：這種機(jī)器是以液力變矩器替代離合器，以液壓力配合電磁閥控制齒輪組的切換，也就是自動換擋；1939年通用汽車在奧茲莫爾比品牌上開始量產(chǎn)并推廣這種變速箱，至此開啟了自動擋汽車的時代。

Automatic transmission: This type of machine uses a hydraulic torque converter instead of a clutch, and uses hydraulic pressure in conjunction with an electromagnetic valve to control the switching of the gear set, that is, automatic shifting; In 1939, General Motors began mass production and promotion of this type of gearbox on the Ozmorby brand, marking the beginning of the era of automatic transmission cars.

離合器陣營：這種機(jī)器是在MT的基礎(chǔ)上，增加電控單元（TCU變速箱電腦），以電機(jī)替代踏板實(shí)現(xiàn)離合器的自動分離與結(jié)合；并且通過電磁閥實(shí)現(xiàn)電控?fù)Q擋，也就是1/2/3/4/5/6前進(jìn)擋在“D擋模式”中的自動升降，使用方式與AT沒有任何區(qū)別，使用壽命與MT也沒有區(qū)別-比較長。

Clutch camp: This machine is based on MT and adds an electronic control unit (TCU transmission computer) to replace the pedal with a motor to achieve automatic clutch separation and combination; And electronic gear shifting is achieved through solenoid valves, which means that the 1/2/3/4/5/6 forward gear automatically rises and falls in the "D gear mode". The usage method is no different from AT, and the service life is no different from MT - it is relatively long.

兩組離合器的變速箱：兩組離合器的變速箱這種機(jī)型是AMT的升級版，由兩組離合器控制兩根動力輸入軸，在換擋時會先行做出準(zhǔn)備結(jié)合檔位的半聯(lián)動動作——做好準(zhǔn)備動作，在分離的瞬間結(jié)合新的前進(jìn)擋，這樣就能讓換擋時間足夠短，換擋前后沒有過大的轉(zhuǎn)速差值，這是保證換擋平順的基礎(chǔ)。

Two clutch gearbox: The two clutch gearbox is an upgraded version of AMT, which is controlled by two sets of clutches to control two power input shafts. When shifting, it will first make a semi linkage action of preparing to engage the gear - prepare for the action, and engage the new forward gear at the moment of separation, so that the shifting time is short enough and there is no significant speed difference before and after shifting, which is the basis for ensuring smooth shifting.
