With the development of, more and more vehicles are repaired by automatic transmission. After buying the car, we need regular maintenance. If there is a problem in the maintenance process, we need to repair it. If the new car fails to pass the maintenance period, you need to pay for it yourself. Since there is a problem, we have to repair at our own expense. Let's tell you what to pay attention to when disassembling the automatic transmission. If there is any additional cost caused by carelessness, the owner is unwilling.

首先，在拆卸之前。

First, before disassembly.

拆卸自動(dòng)變速器前，檢查庫(kù)存中是否有相應(yīng)的自動(dòng)變速器型號(hào)。如果達(dá)不到易損件和更換件的數(shù)量，不建議拆卸。

Before removing the automatic transmission, check whether there is a corresponding automatic transmission model in stock. If the quantity of vulnerable parts and replacement parts cannot be reached, disassembly is not recommended.

先排掉變速箱油，取出u盤(pán)，檢查殘油雜質(zhì)部分。正常情況下，深棕色或棕色粉末是離合器片的磨損，而白色金屬粉末是油泵、單向離合器和齒輪機(jī)構(gòu)的磨損，從而進(jìn)一步判斷汽車(chē)的故障。

Drain the transmission oil first, take out the U-disk and check the residual oil and impurities. Under normal circumstances, dark brown or brown powder is the wear of clutch plate, while white metal powder is the wear of oil pump, one-way clutch and gear mechanism, so as to further judge the fault of automobile.

2.在自動(dòng)變速箱的維護(hù)過(guò)程中拆卸它。

2. Disassemble the automatic transmission during its maintenance.

由于車(chē)身底部形狀和位置的限制，變速箱通常不會(huì)直接從發(fā)動(dòng)機(jī)后部拆下。更好的方法是將變速箱和發(fā)動(dòng)機(jī)一起從車(chē)上提起。

Due to the limitation of the shape and position of the underbody, the transmission is usually not removed directly from the rear of the engine. A better way is to lift the transmission and engine from the vehicle.

當(dāng)自動(dòng)變速器從發(fā)動(dòng)機(jī)中拉出時(shí)，應(yīng)沿軸向拉出，并沿軸向順時(shí)針和逆針旋轉(zhuǎn)，但不應(yīng)上下、左右擺動(dòng)，以免損壞自動(dòng)變速器輸入軸與液力偶合器或變矩器之間的表面狀況和連接比。

When the automatic transmission is pulled out from the engine, it shall be pulled out along the axial direction and rotated clockwise and counterclockwise along the axial direction, but it shall not swing up and down, left and right, so as not to damage the surface condition and connection ratio between the input shaft of the automatic transmission and the hydraulic coupling or torque converter.

3.修理后，以后再安裝。

3. Install after repair.

準(zhǔn)備好不同零件的工具和小盒子，在干凈平整的操作平臺(tái)上拆解，從前機(jī)油泵開(kāi)始，從前到后，從外到內(nèi)逐步拆解，并做好記錄。

Prepare tools and small boxes of different parts, disassemble them on a clean and flat operating platform, starting from the front oil pump, from front to back, from outside to inside, and make records.

拆裝時(shí)切記不要用撬棍和鐵直接敲擊，因?yàn)樽詣?dòng)變速器的外殼大部分都是鋁合金的。拆卸液壓控制閥閥體時(shí)，防止上下閥體分離時(shí)球和卡環(huán)落地。準(zhǔn)確記住正確的位置。拆卸單向離合器時(shí)，注意正確的裝配方向，裝配時(shí)不要倒轉(zhuǎn)。拆卸后用汽油清洗零件，確保零件清潔。

Remember not to knock with crowbar and iron directly when disassembling, because most of the shell of automatic transmission is made of aluminum alloy. When removing the hydraulic control valve body, prevent the ball and snap ring from falling to the ground when the upper and lower valve bodies are separated. Remember the correct position accurately. When removing the one-way clutch, pay attention to the correct assembly direction and do not reverse during assembly. Clean the parts with gasoline after disassembly to ensure that the parts are clean.

更換離合器片或制動(dòng)片時(shí)，應(yīng)將其浸泡在變速器油中，并在吸收油后再進(jìn)行組裝。請(qǐng)注意，在組裝過(guò)程中，應(yīng)嚴(yán)格按照規(guī)定的扭矩?cái)Q緊螺釘。

When replacing the clutch plate or brake plate, soak it in the transmission oil and assemble it after absorbing the oil. Please note that during assembly, the screws should be tightened in strict accordance with the specified torque.
