As the models of automatic transmission are convenient to drive on urban roads, the share is increasing. However, the structure of automatic transmission is complex compared with manual transmission. Once damaged, the maintenance process is more difficult. The maintenance process of automatic transmission can be divided into the following three steps.

在拆卸自動變速箱之前一定要查找庫存是否有對應的自動變速箱型號，在不能保證起碼的易損件和必換件都充沛的情況下，不建議立即拆卸解體。

Before disassembling the automatic transmission, it is necessary to find out whether there is a corresponding automatic transmission model in stock. It is not recommended to disassemble it immediately if it cannot be guaranteed that there are sufficient vulnerable parts and necessary replacement parts.

可先放干變速箱機油，卸下優盤，檢車殘油品種的雜質部分，在正常情況下，含有深褐色或褐色粉末為離合器片磨損，亮白色金屬粉末為油泵、單向離合器、齒輪機構磨損，從而進一步判斷車子的故障。

Drain the transmission oil first, remove the USB flash disk, and check the impurities of the residual oil. Under normal circumstances, the dark brown or brown powder is the wear of the clutch plate, and the bright white metal powder is the wear of the oil pump, one-way clutch and gear mechanism, so as to further judge the fault of the car.

拆卸時

During disassembly

因車身底板形狀個位置的限制，直接從發動機后部拆下變速箱往往顯得空間不夠，可靠的辦法是連同發動機一同從車上吊下。

Due to the limitation of the shape and position of the underbody, it is often insufficient to remove the gearbox directly from the rear of the engine. The reliable way is to lift it from the vehicle together with the engine.

把自動變速箱拉離發動機時，應該沿著軸向拉動，克伴以繞軸線的順和反方向轉動，但不得上下左右擺動，以免損壞自動變速箱輸入軸與液力耦合器或變矩器連接比分的表面狀況與配合。

When the automatic transmission is pulled away from the engine, it shall be pulled along the axial direction to rotate in the forward and reverse directions around the axis, but it shall not swing up, down, left and right, so as not to damage the surface condition and fit of the connection between the input shaft of the automatic transmission and the hydraulic coupler or torque converter.

解體與裝合

Disassembly and assembly

首先準備好工具及盛放各類零件的小盒子，在干凈平整的操作臺上進行解體，從前部油泵開始，從前至后，由外向里逐步進行，并做好記錄。

First, prepare tools and small boxes containing various parts, disassemble them on a clean and flat console, start from the front oil pump, from front to back, step by step from outside to inside, and make records.

在拆卸的時候，一定要記住不能用撬棍和鐵器直接敲打，因自動變速箱殼體大多數用鋁合金鑄成，在拆卸液控閥體是防止上下閥體分離時滾珠、卡環等掉地，要準確記住正確位置，拆卸單向離合器要注意正確配裝方向，裝合時不能顛倒，零件拆卸后應用汽油洗凈，確保各元件的清潔。

During disassembly, it must be remembered that crowbars and irons cannot be used to directly knock, because most of the automatic transmission shells are made of aluminum alloy. When disassembling the hydraulic control valve body, it is to 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. Pay attention to the correct assembly direction when disassembling the one-way clutch, and do not reverse the assembly. Wash the parts with gasoline after disassembly, Ensure that all components are clean.

如更換新離合器片、制動片應在變速箱油中浸泡，待吸足油后才能裝合，另外一定要注意，裝合時嚴格按照規定力矩擰緊螺釘。

If new clutch plates and brake pads are replaced, they shall be soaked in the transmission oil and assembled only after sufficient oil is absorbed. In addition, it must be noted that the screws shall be tightened in strict accordance with the specified torque during assembly.

自動變速箱出現故障大多數是由于車主使用不當造成的，部分車主總是認為自動變速箱油不需要更換、自動變速箱進水也不需要理會，導致變速箱的損傷越來越大，甚至報廢。為了保障廣大車主的行車安全，各位在平常行車中一定要正確使用車輛，一旦車子出現問題一定要及時送往公司進行檢查維修，以免造成大患！

Most of the failures of the automatic transmission are caused by improper use of the vehicle owner. Some vehicle owners always think that the automatic transmission oil does not need to be replaced and the automatic transmission water does not need to be ignored, resulting in more and more damage to the transmission and even scrapping. In order to ensure the driving safety of the majority of car owners, you must use the vehicle correctly during normal driving. Once the vehicle has problems, you must send it to a professional company for inspection and maintenance in time to avoid serious problems!
