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、一般不管是手動變速箱還是自動變速箱建議更長12個月或二萬公里更換一次自動變速箱油，也有的車型的使用說明書上寫著24個月或四萬公里更換。

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.

上述只是一般情況下的建議，根據當地氣候、道路、空氣情況，建議車主要定期檢查及時更換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、或遇變速箱打滑、水溫偏高、換擋遲緩、或遇系統滲漏時清洗保養一次

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

自動波箱深度保養的意義

Significance of deep maintenance of automatic wave box

清除有害的油泥和漆膜沉積物，恢復密封墊和O型圈的彈性，使變速箱換檔平順，提高動力輸出，徹底更換舊的自動變速箱油。

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會阻塞系統，是變速不靈敏，動力輸出不暢，為行車安全帶來安全隱患。

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.

更換施工特點

Replacement construction features

1在恒溫條件下對自動變速箱進行清洗，避免了以往換油時由于新舊油溫差過大，引起變速箱內部元件尺寸變化對變速箱造成的危害。

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通過精密的測定保證在等溫條件下，確保達到99%以上的新舊油交換率！避免由于交換率過低,新油使用壽命縮短對變速箱的傷害。

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.

一般在更換自動變速箱油時大都是卸下自動變速箱油底的螺絲來漏掉舊油再加入新油，但這樣大約只能換上30%的新油，而還有70%的舊油仍殘留在變速箱內。如果以拆卸油底殼的方式進行換油，則可達到70%的換油率，這樣其實就已經能確保變速箱的健康了。

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.

但目前較好的換油方法是動態換油，采用專用的變速箱清洗設備，在變速箱運轉的過程中，將舊油充分循環、排放干凈后再加入新的變速箱油，從而使換油率高達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、豐田、福特等品牌的自動變速箱的摩擦系數不同，所以ATF油不同，不能混用。混用ATF，會造成變速箱的摩擦片損壞，出現離合器、制動器打滑等現象，嚴重的則會毀掉摩擦片。

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.
