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.

這不是危言聳聽。根據多年的自動齒輪箱維修經驗，自動齒輪箱故障中85%來自于自動齒輪箱油。

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，如何正確維護自動變速箱油呢？

So, how to maintain the automatic transmission oil correctly?

1。始終檢查自動變速箱流體是否正常。自動變速箱油的檢驗方法不同于發動機油的檢驗方法。自動變速箱油需要預熱到50°C左右，然后變速器拉桿在每個齒輪中停留2秒鐘，然后將其放入停車齒輪中。

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。變速箱維修價格是車輛上非常重要的部件，它可以改變傳動比，擴大驅動輪轉矩和轉速的作用。隨著現代科技的發展，變速箱也有了升級，從更初的手動變速箱，到現在無級變速箱，從無同步器到有同步器，操控越來越方便。掌握自動變速箱油的更換周期。大多數制造商建議在兩年內采用自動變速箱換油周期或4至600萬公里。齒輪箱油長期使用會產生油脂，形成油泥，增加摩擦片及各部件的磨損，影響系統的油壓，影響動力傳遞，造成自動變速箱的故障。

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。變速箱維修主要指的是汽車的變速箱，它分為手動、自動兩種，手動變速箱主要由齒輪和軸組成，通過不同的齒輪組合產生變速變矩；而自動變速箱AT是由液力變扭器、行星齒輪、液壓變距系統和液壓操縱系統組成。通過液力傳遞和齒輪組合的方式來達到變速變矩。正確更換自動變速箱油。目前，較好的換油方法是動態換油。使用特殊的自動變速箱清潔設備。在齒輪箱運行過程中，舊油完全回收，排放后加入新的自動變速箱油，換油率高達90%。5%以上，以保證換油效果。

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.
