變速箱共分5種：①手動變速箱MT②自動變速箱AT ③手自一體變速箱AT/MT ④無極變速箱CVT⑤雙離合變速箱DCT（DSG）
There are 5 types of transmission: ① manual transmission MT ② automatic transmission at ③ manual automatic transmission at / MT ④ stepless transmission CVT ⑤ double clutch transmission DCT (DSG)
一、手動變速箱優點：隨意掌握換擋時機，良好的駕駛樂趣、省油缺點：操作性復雜、上手難度高點評：老一批考駕駛證的都知道：一踩離合二掛擋，說的就是手動檔
1、 Advantages of manual transmission: random control of shift timing, good driving fun and fuel saving disadvantages: complex operability and high difficulty in getting started comments: the old batch of drivers who test their driver's license know: step on clutch and engage in gear, which means manual gear
二、自動變速箱優點：操控簡單、上手快、適合新手缺點：技術陳舊、動力燃油經濟性不如手動變速器點評：現在的人都比較懶，喜歡買自動擋，踩油門就走，省事
2、 Advantages of automatic transmission: simple operation, quick start, suitable for novices disadvantages: old technology, power and fuel economy are not as good as manual transmission comments: people are lazy now, like to buy automatic gear and step on the accelerator to save trouble
三、手自一體變速箱優點：手動自動自由切換、燃油經濟性和舒適性好缺點：手動模式不能完全手動、使用成本和維修費用高點評：想懶，又想省油，于是發明了它
3、 Advantages of manual automatic transmission: manual automatic free switching, good fuel economy and comfort disadvantages: manual mode can not be completely manual, high use cost and maintenance cost comments: I want to be lazy and save fuel, so I invented it
四、無極變速箱優點無頓挫感、動力持續且順暢、油耗低缺點加速感差、可承受的扭矩偏小點評：前面三種還要手動或自動跳檔，這種 CVT連檔都不用跳，直接用兩個甩盤變速
4、 Limitless gearbox has the advantages of no sense of frustration, continuous and smooth power, low fuel consumption, poor acceleration sense and small maximum torque. Comments: the first three types also need to manually or automatically skip gears. This CVT doesn't even need to skip gears, and directly uses two swing discs for speed change
五、雙離合變速箱DCT（DSG）優點換擋快、幾乎無扭矩損失、降低15%燃油消耗、幾乎無頓挫感缺點成本比較高，穩定性差點評：DCT分干式和濕式，其設計來自于賽車運動，主要是為了更快傳遞動力和切斷動力！一般車才裝這個
5、 Double clutch gearbox DCT (DSG) has the advantages of fast shift, almost no torque loss, 15% reduction in fuel consumption, almost no sense of frustration, high cost and poor stability. Comments: DCT is divided into dry and wet. Its design comes from racing sports, mainly to transfer power and cut off power faster! This is usually installed on high-end cars
