因?yàn)檐?chē)輛結(jié)構(gòu)的緣故，很難自己去檢查自動(dòng)變速箱油，一般情況下，出現(xiàn)問(wèn)題多的就是變速箱的加油口和放油口，在維修保養(yǎng)或更換變速箱油以后，建議各位車(chē)主仔細(xì)檢查。下面來(lái)講講更換濟(jì)南變速箱油正確的更換步驟。

Due to the structure of the vehicle, it is difficult to check the automatic transmission oil by yourself. Generally, the oil filler and drain port of the transmission are the main problems. After maintenance or replacement of the transmission oil, it is recommended that you carefully check. Next, we will talk about the correct replacement steps for Jinan transmission oil.

目前市面常見(jiàn)的換油方式主要分成2種：泄放式、與拆油底殼式。由于變速箱內(nèi)的油道相當(dāng)復(fù)雜，不若引擎般簡(jiǎn)單，若采省事的自然泄放方式更換，整個(gè)換油率大約只到30﹪，有一半以上的自動(dòng)油都還停留在扭力轉(zhuǎn)換器內(nèi)，換油率比較低，除非必要否則不會(huì)采用此種方法來(lái)更換自動(dòng)油。

At present, the common oil change methods on the market are mainly divided into two types: drain type and oil pan removal type. Since the oil passage in the gearbox is quite complex and not as simple as the engine, if it is replaced by an easy natural discharge method, the overall oil change rate will only be about 30%. More than half of the automatic oil still stays in the torque converter, so the oil change rate is relatively low. Unless necessary, this method will not be used to replace the automatic oil.

至于拆卸油底殼的方式進(jìn)行換油，雖然多數(shù)車(chē)的換油率只達(dá)40%，但這已足以對(duì)應(yīng)多數(shù)車(chē)輛的使用環(huán)境與需求，只要下次在原廠建議的周期再換油，油質(zhì)衰退的速度還在可接受范圍內(nèi)，加上對(duì)變速箱比較溫和、施工難度也不高（有些細(xì)節(jié)要特別注意），所需時(shí)間也相當(dāng)快速，更重要的是沒(méi)有拆卸變速箱油底殼的話，無(wú)法更換到內(nèi)部的過(guò)濾網(wǎng)（有些車(chē)型無(wú)法更換），濾網(wǎng)一直沒(méi)有更換，變速箱內(nèi)的雜質(zhì)就無(wú)法有效過(guò)濾，甚至?xí)绊懽詣?dòng)油的流動(dòng)，嚴(yán)重時(shí)會(huì)造成明顯的換檔頓挫情況，也因?yàn)檫@種拆卸油底殼來(lái)更換自動(dòng)油的方式有很多優(yōu)點(diǎn)，因此成為目前多數(shù)車(chē)廠采用的主流方式。

As for oil change by disassembling the oil pan, although the oil change rate of most vehicles is only 40%, this is enough to meet the service environment and demand of most vehicles. As long as the oil is changed at the interval recommended by the original manufacturer next time, the speed of oil quality deterioration is still acceptable. In addition, the gearbox is mild, and the construction is not difficult (some details should be paid special attention to). The time required is also quite fast, More importantly, if the transmission oil pan is not removed, the internal filter screen cannot be replaced (some models cannot be replaced). If the filter screen has not been replaced, impurities in the transmission can not be filtered effectively, and even affect the flow of automatic oil. In serious cases, it will cause obvious gear shift jerks, because this method of removing the oil pan to replace automatic oil has many advantages, Therefore, it has become the mainstream mode adopted by most car manufacturers.

自動(dòng)油的濾網(wǎng)若一直沒(méi)有更換，會(huì)影響自動(dòng)油的流動(dòng)，嚴(yán)重時(shí)會(huì)造成明顯的換檔頓挫，因此更換自動(dòng)油時(shí)，若有變速箱油底殼的話，建議拆下油底殼來(lái)進(jìn)行換油與換濾芯的動(dòng)作。

If the filter screen of automatic oil has not been replaced all the time, it will affect the flow of automatic oil, and even cause obvious gear shift jerk. Therefore, when replacing automatic oil, if there is a transmission oil pan, it is recommended to remove the oil pan to change the oil and filter element.

將油底殼鎖回去時(shí)，由于有些進(jìn)口車(chē)輛的固定螺絲是較軟的鋁合金，長(zhǎng)時(shí)間承受自動(dòng)油的熱漲冷縮下，容易出現(xiàn)金屬疲勞，因此只要拆下來(lái)后需要更換新螺絲，并且使用扭力板手來(lái)上鎖，以確保螺絲不會(huì)鎖壞。

When the oil pan is locked back, because the fixing screws of some imported vehicles are made of soft aluminum alloy, which can withstand the thermal expansion and cold contraction of the automatic oil for a long time, and are prone to metal fatigue, it is necessary to replace the screws after removal, and use a torque wrench to lock them to ensure that the screws will not be damaged.

而更換自動(dòng)油中，需要注意的就是換油時(shí)的變速箱溫度需降低到常溫狀態(tài)下才能進(jìn)行（通常是前先進(jìn)廠靜置一晚），至少讓自動(dòng)油溫冷卻至35度后再能更換新油，原因在于自動(dòng)箱內(nèi)泡在油里面的油壓閥體，內(nèi)部為細(xì)小油道所組成，且為上下兩片合為一體。

In the process of changing the automatic oil, it should be noted that the gearbox temperature should be reduced to normal temperature before changing the oil (usually the day before last, the gearbox should be left in the factory overnight). At least the automatic oil temperature should be cooled to 35 ℃ before changing the new oil. The reason is that the oil pressure valve body inside the automatic oil box, which is soaked in the oil, is composed of small oil passages, and the upper and lower parts are integrated.

若未待油溫冷卻才更換溫度較低的新油，有可能因高低溫變化過(guò)大，導(dǎo)致整個(gè)閥體熱漲冷縮不均而變形，使得內(nèi)部油道產(chǎn)生密封不全漏油，油壓無(wú)法建立的問(wèn)題，屆時(shí)只能更換整個(gè)閥體才能解決跳檔不順或頓挫嚴(yán)重的問(wèn)題。

If the new oil with lower temperature is not replaced until the oil temperature is cooled, it may be deformed due to uneven thermal expansion and contraction of the whole valve body due to excessive changes in high and low temperatures, resulting in incomplete sealing of the internal oil passage and oil leakage, and the oil pressure cannot be established. At that time, only the whole valve body can be replaced to solve the problem of unsmooth gear jump or serious setback.

有些車(chē)輛上并沒(méi)有自動(dòng)油尺可測(cè)試油量，因此泄油時(shí)要以量壺來(lái)盛裝，看泄下的油量為多少后，才知道要補(bǔ)充多少新油進(jìn)變速箱內(nèi)，通常依照經(jīng)驗(yàn)會(huì)多倒1升的自動(dòng)油于填充的容器內(nèi)，再視情況補(bǔ)進(jìn)自動(dòng)變速箱內(nèi)。

Some vehicles do not have an automatic oil dipstick to test the oil level, so when draining the oil, a measuring pot should be used to fill it. After checking the amount of oil drained, we can know how much new oil to add into the gearbox. Generally, according to experience, we will pour an additional liter of automatic oil into the filled container, and then add it into the automatic gearbox as the case may be.

自動(dòng)油更換時(shí)一定要在冷車(chē)狀態(tài)下進(jìn)行，這樣才不會(huì)導(dǎo)致內(nèi)部閥體變形，且補(bǔ)充新油時(shí)不得讓自動(dòng)油溫超過(guò)45度，超過(guò)這個(gè)溫度會(huì)因?yàn)樽詣?dòng)油的熱脹而使油量判斷失準(zhǔn)，導(dǎo)致油量填充過(guò)少，因此需診斷電腦協(xié)助才能進(jìn)行。大家還有補(bǔ)充的歡迎評(píng)論留下http://www.fdwhkj.cn你的經(jīng)驗(yàn)，或者你遇到的問(wèn)題。

The automatic oil must be replaced in the cold state, so as not to cause deformation of the internal valve body, and the automatic oil temperature shall not exceed 45 degrees when replenishing new oil. If the temperature exceeds this, the oil volume will be judged inaccurate due to the thermal expansion of the automatic oil, resulting in too little oil filling. Therefore, it can only be carried out with the assistance of the diagnostic computer. You have additional welcome comments left http://www.fdwhkj.cn Your experience, or your problems.
