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.

所以定期维修保养变速箱是必不可少的。我们要做到变速箱油要定期更换。变速箱油除了像一般油液一样具有润滑、散热、清洁、防锈等作用外，变速箱油还负责力的传递

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

当车子行驶到一定的数后变速箱油的润滑及散热及清洁效果会下降，加上机器齿轮磨损出来的铁粉影响着变速箱的驱动效果，所以长时间不换会导致换档顿挫异响，起步有冲击，烧掉电池阀，烧掉电脑板。甚变速箱大修，据统计，80%的自动变速器故障是由于变速箱油污染劣化引起的，20%是由于车主平常开车习惯导致。但还有很多车主客户对变速箱渍的定期更换不够重视

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
