In the last issue, the editor explained the disassembly and assembly precautions and other related issues during the maintenance of the automatic gearbox. In this issue, what are the characteristics of the automatic gearbox in the replacement construction? Next, I will give you a detailed explanation on this issue.

1、一般不管是手动变速箱还是自动变速箱建议更长12个月或二万更换一次自动变速箱油，也有的车型的使用说明书上写着24个月或四万更换。

1. Generally, it is recommended to change the automatic transmission oil once in 12 months or 20000 kilometers at most for manual transmission or automatic transmission. In some models, the operation manual says 24 months or 40000 kilometers.

上述只是一般情况下的建议，根据当地气候、道路、空气情况，建议车主要定期检查及时更换ATF。

The above is only a general recommendation. According to the local climate, road and air conditions, it is recommended that the vehicle should check regularly and replace the ATF in time.

2、或遇变速箱打滑、水温偏高、换挡迟缓、或遇系统渗漏时清洗保养一次

2. Or in case of gearbox slipping, high water temperature, slow shifting, or in case of system leakage, clean and maintain once

自动波箱深度保养的意义

Significance of deep maintenance of automatic wave box

有害的油泥和漆膜沉积物，恢复密封垫和O型圈的弹性，使变速箱换档平顺，提高动力输出，彻底更换旧的自动变速箱油。

Remove the harmful sludge and paint film deposits, restore the elasticity of the gasket and O ring, make the transmission shift smoothly, improve the power output, and completely replace the old automatic transmission oil.

不做的危害

Harm of not doing

油泥和漆膜的沉淀物会阻塞系统，是变速不灵敏，动力输出不畅，为行车带来隐患。

The deposits of oil mud and paint film will block the system, which is insensitive to speed change and poor power output, bringing potential safety hazards for driving safety.

更换施工特点

Replacement construction features

1在恒温条件下对自动变速箱进行清洗，避免了以往换油时由于新旧油温差过大，引起变速箱内部元件尺寸变化对变速箱造成的危害。

1. Under constant temperature condition, the automatic gearbox is cleaned to avoid the damage to the gearbox caused by the size change of the internal components of the gearbox due to the excessive temperature difference between the old and new oil in the past oil change.

2通过精密的测定保证在等温条件下，确保达到99%以上的新旧油交换率！避免由于交换率过低,新油使用寿命缩短对变速箱的伤害。

2. Ensure that the exchange rate of new and old oil is over 99% under isothermal condition through precise measurement! Avoid the damage to the gearbox due to the low exchange rate and the shortened service life of new oil.

一般在更换自动变速箱油时大都是卸下自动变速箱油底的螺丝来漏掉旧油再加入新油，但这样大约只能换上30%的新油，而还有70%的旧油仍残留在变速箱内。如果以拆卸油底壳的方式进行换油，则可达到70%的换油率，这样其实就已经能确保变速箱的健康了。

In general, when changing the automatic transmission oil, it is mostly to remove the screws on the oil bottom of the automatic transmission to leak out the old oil and then add new oil, but in this way, only about 30% of the new oil can be replaced, and 70% of the old oil is still left in the transmission. If the oil is changed by removing the oil pan, the oil change rate can reach 70%, which can ensure the health of the transmission.

但目前较好的换油方法是动态换油，采用专用的变速箱清洗设备，在变速箱运转的过程中，将旧油充分循环、排放干净后再加入新的变速箱油，从而使换油率高达90%以上。

But at present, the better oil change method is dynamic oil change. The special gearbox cleaning equipment is used. In the process of gearbox operation, the old oil is fully recycled and drained before adding new gearbox oil, so that the oil change rate can reach more than 90%.

通用、丰田、福特等的自动变速箱的摩擦系数不同，所以ATF油不同，不能混用。混用ATF，会造成变速箱的摩擦片损坏，出现离合器、制动器打滑等现象，严重的则会毁掉摩擦片。

The friction coefficient of automatic transmission of GM, Toyota, Ford and other brands is different, so ATF oil is different and cannot be mixed. If ATF is mixed, the friction plate of gearbox will be damaged, and the clutch and brake will slip. If it is serious, the friction plate will be destroyed.
