Jinan automatic transmission maintenance is engaged in automatic transmission maintenance. Over the years, he has repaired several automatic transmissions and disassembled many gearboxes. As the saying goes, "practice makes perfect". Jinan automatic transmission maintenance personnel have already fully recognized the disassembly and assembly of automatic transmission. Based on this, the whole process of gearbox disassembly and assembly is summarized as follows:

1.準備好拆卸過程中需要使用到的工具及盛放各類零件的小盒，在干凈平整的操作臺上進行變速箱解體。如果沒有該車的維修手冊，應準備好記錄本和做記號的膠布條。若是在的自動變速箱維修公司則可必須要這么麻煩。

1. Prepare the tools to be used in the disassembly process and the small box for holding various parts, and disassemble the gearbox on the clean and flat operation platform. If there is no maintenance manual for the vehicle, prepare the record book and tape for marking. If it is in the professional automatic transmission maintenance company, it must be so troublesome.

2.拆卸應從前部油泵開始，由前至后，由外及里地逐步進行，并隨時做好記錄。

2. The disassembly should start from the front oil pump, from the front to the back, from the outside to the inside, and make records at any time
.

3.自動變速箱殼體大多是使用鋁合金鑄成的，在拆卸時，嚴禁使用撬棍和鐵器直接敲打。

3. The case of automatic transmission is mostly made of aluminum alloy. It is strictly forbidden to use crowbar and iron to knock directly during disassembly.

4.拆卸液控閥體時，應小心仔細，上下閥體分離時要防止滾珠，卡環等掉地，要準確記住每個零件的正確位置。

4. When disassembling the hydraulic control valve body, be careful. When separating the upper and lower valve bodies, prevent the ball and snap ring from falling to the ground, and accurately remember the correct position of each part.

5.拆檢單向離合器時，必須注意其正確的配裝方向，裝合時，決不能顛倒。

5. When disassembling and checking the one-way clutch, attention must be paid to its correct assembly direction. When assembling, it must not be reversed.

6.零件拆卸后，應用煤油洗凈，并用空壓機或其他低壓壓縮空氣設備進行吹干，不得使用易掉纖維的棉紗等擦拭閥類零件。

6. After the parts are disassembled, they shall be cleaned with kerosene and dried by air compressor or other low-pressure compressed air equipment. Cotton yarn which is easy to lose fiber and other parts shall not be used to wipe valve parts.

7.墊上O型密封圈等易損件原則上拆卸后應更換新件，不得湊合重復使用老化、變形、磨損的易損件。

7. Put on O-ring and other vulnerable parts. In principle, replace them with new ones after disassembly. Do not make use of aging, deformed and worn parts repeatedly.

8.新離合器片、制動器片應在變速箱油中浸泡2h，待吸足油后才能裝合。

8. The new clutch plate and brake plate should be soaked in the transmission oil for 2 h, and can not be assembled until the oil is fully absorbed.

9.閥芯、活塞、密封件等裝合時，均應涂上變速箱油。

9. When valve core, piston and seal are assembled, they should be coated with transmission oil.

10.裝合時，嚴格按規定力矩擰緊各部位部件的螺釘。

10. When assembling, tighten the screws of all parts in strict accordance with the specified torque.
