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.准备好拆卸过程中需要使用到的工具及盛放各类零件的小盒，在干净平整的操作台上进行变速箱解体。如果没有该车的维修手册，应准备好记录本和做记号的胶布条。若是在的自动变速箱维修公司则可必须要这么麻烦。

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.拆卸应从前部油泵开始，由前至后，由外及里地逐步进行，并随时做好记录。

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.自动变速箱壳体大多是使用铝合金铸成的，在拆卸时，严禁使用撬棍和铁器直接敲打。

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.拆卸液控阀体时，应小心仔细，上下阀体分离时要防止滚珠，卡环等掉地，要准确记住每个零件的正确位置。

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.拆检单向离合器时，必须注意其正确的配装方向，装合时，决不能颠倒。

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，应用煤油洗净，并用空压机或其他低压压缩空气设备进行吹干，不得使用易掉纤维的棉纱等擦拭阀类零件。

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.垫上O型密封圈等易损件原则上拆卸后应更换新件，不得凑合重复使用老化、变形、磨损的易损件。

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.新离合器片、制动器片应在变速箱油中浸泡2h，待吸足油后才能装合。

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.阀芯、活塞、密封件等装合时，均应涂上变速箱油。

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

10.装合时，严格按规定力矩拧紧各部位部件的螺钉。

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