The automatic transmission oil also has the functions of transmission, lubrication, hydraulics and heat dissipation, which will inevitably produce various impurities, such as debris, sludge, gel, etc. Although the filter of the automatic transmission itself can filter impurities, the residual impurities will still rub with the automatic transmission oil. With the passage of time, automatic transmission will appear abnormal noise, oil leakage, impact, sliding and other high-risk factors.

这不是危言耸听。根据多年的自动齿轮箱维修经验，自动齿轮箱故障中85%来自于自动齿轮箱油。

It's not alarmist. According to years of maintenance experience of automatic gearbox, 85% of the faults of automatic gearbox come from automatic gearbox oil.

那么，如何正确维护自动变速箱油呢？

So, how to maintain the automatic transmission oil correctly?

1。始终检查自动变速箱流体是否正常。自动变速箱油的检验方法不同于发动机油的检验方法。自动变速箱油需要预热到50°C左右，然后变速器拉杆在每个齿轮中停留2秒钟，然后将其放入停车齿轮中。

1。 Always check that the automatic transmission fluid is normal. The inspection method of automatic transmission oil is different from that of engine oil. The automatic transmission oil needs to be preheated to about 50 ° C, then the transmission rod stays in each gear for 2 seconds, and then it is put into the parking gear.

2。变速箱维修价格是车辆上非常重要的部件，它可以改变传动比，扩大驱动轮转矩和转速的作用。随着现代科技的发展，变速箱也有了升级，从更初的手动变速箱，到现在无级变速箱，从无同步器到有同步器，操控越来越方便。掌握自动变速箱油的更换周期。大多数制造商建议在两年内采用自动变速箱换油周期或4至600万公里。齿轮箱油长期使用会产生油脂，形成油泥，增加摩擦片及各部件的磨损，影响系统的油压，影响动力传递，造成自动变速箱的故障。

2。 Gearbox maintenance price is a very important part of the vehicle, it can change the transmission ratio, expand the role of driving wheel torque and speed. With the development of modern science and technology, the gearbox has also been upgraded. From the original manual gearbox to the present continuously variable gearbox, from no synchronizer to synchronizer, the control is more and more convenient. Master the change cycle of automatic transmission oil. Most manufacturers recommend an automatic transmission oil change cycle or 4 to 6 million km within two years. The long-term use of gearbox oil will produce grease, form sludge, increase the wear of friction plates and components, affect the oil pressure of the system, affect the power transmission, and cause the failure of automatic transmission.

3。变速箱维修主要指的是汽车的变速箱，它分为手动、自动两种，手动变速箱主要由齿轮和轴组成，通过不同的齿轮组合产生变速变矩；而自动变速箱AT是由液力变扭器、行星齿轮、液压变距系统和液压操纵系统组成。通过液力传递和齿轮组合的方式来达到变速变矩。正确更换自动变速箱油。目前，较好的换油方法是动态换油。使用特殊的自动变速箱清洁设备。在齿轮箱运行过程中，旧油完全回收，排放后加入新的自动变速箱油，换油率高达90%。5%以上，以保证换油效果。

3。 Gearbox maintenance mainly refers to the automobile gearbox, which is divided into manual and automatic. Manual gearbox is mainly composed of gears and shafts, which produce variable speed torque through different gear combinations; while automatic gearbox at is composed of hydraulic torque converter, planetary gear, hydraulic torque control system and hydraulic control system. Through the way of hydraulic transmission and gear combination to achieve variable speed and torque. Change the automatic transmission oil correctly. At present, dynamic oil change is a better method. Use special automatic transmission cleaning equipment. During the operation of the gearbox, the old oil is completely recovered, and the new automatic transmission oil is added after discharge. The oil change rate is up to 90%. 5% to ensure the oil change effect.
