Automobile gearbox is one of the core components of automobile. It can change the transmission ratio and expand the torque and speed of driving wheel. The engine can start and change speed, and it is convenient for the transmission to shift or take off power. With the development of modern science and technology, the gearbox has been upgraded. From manual gearbox to CVT, the control is more and more convenient. As the core component of the car, if the gearbox fails, the cost of maintenance can be imagined.

所以定期維修保養變速箱是必不可少的。首先我們要做到變速箱油要定期更換。變速箱油除了像一般油液一樣具有潤滑、散熱、清潔、防銹等作用外，變速箱油還負責力的傳遞

So regular maintenance of the gearbox is essential. First of all, we should change the transmission oil regularly. In addition to the functions of lubrication, heat dissipation, cleaning and rust prevention, transmission oil is also responsible for the transmission of force

當車子行駛到一定的公里數后變速箱油的潤滑及散熱及清潔效果會下降，加上機器齒輪磨損出來的鐵粉影響著變速箱的驅動效果，所以長時間不換會導致換檔頓挫異響，起步有沖擊，燒掉電池閥，燒掉電腦板。甚至變速箱大修，據統計，80%的自動變速器故障是由于變速箱油污染劣化引起的，20%是由于車主平常開車習慣導致。但還有很多車主客戶對變速箱漬的定期更換不夠重視

When the car runs to a certain number of kilometers, the lubrication, heat dissipation and cleaning effect of the transmission oil will decrease. In addition, the iron powder worn out by the machine gears will affect the driving effect of the transmission, so long-term non replacement will lead to gear shifting faltering and abnormal noise, impact at the start, burn off the battery valve and the computer board. Even the gearbox overhaul, according to statistics, 80% of the automatic transmission failure is caused by the deterioration of the transmission oil pollution, 20% is caused by the car owners' usual driving habits. However, many car owners and customers do not pay enough attention to the regular replacement of the gearbox
