自动变速箱维修不能避免拆卸和组装变速箱。自动变速器的核心是实现自动换挡，所谓自动换挡，是指驾驶员在汽车行驶时根据行驶过程的需要操纵油门踏板（加速踏板），自动变速器可以根据发动机负荷和汽车的档位自动换挡，运行条件。变速箱的保养开始，空转停止，低速或高速行驶，加速，减速，爬升和倒车等，这需要在很大范围内改变汽车的驱动力和速度，并且目前已广泛使用 活塞发动机输出扭矩和变速范围很小。为了适应频繁变化的驾驶条件并使发动机在有利的工作条件（更高的功率和更低的燃油消耗）下工作，在变速器系统中安装了一个变速器。在自动变速器维护的情况下，次要问题并不表示在严重损坏自动变速器的情况下，为了从根本上解决问题，需要拆卸和修理自动变速器。当然，有时还需要消除一些小问题以进行检查和维护。因此，变速箱的拆卸和组装至关重要。如果不注意，在拆卸过程中可能会损坏变速箱。这样，变速箱拆卸和组装的整个过程总结如下：

Automatic transmission maintenance cannot avoid disassembling and assembling the transmission. The core of an automatic transmission is to achieve automatic shifting. The so-called automatic shifting refers to the driver manipulating the accelerator pedal (accelerator pedal) according to the needs of the driving process while the car is in motion. The automatic transmission can automatically shift gears according to the engine load and the gear position of the car, depending on the operating conditions. The maintenance of the gearbox begins, including idle stop, low-speed or high-speed driving, acceleration, deceleration, climbing, and reversing, which require a wide range of changes in the driving force and speed of the car. Currently, piston engines are widely used with small output torque and transmission range. In order to adapt to frequently changing driving conditions and operate the engine under favorable working conditions (higher power and lower fuel consumption), a transmission is installed in the transmission system. In the case of automatic transmission maintenance, minor issues do not necessarily mean that in order to fundamentally solve the problem of severe damage to the automatic transmission, it is necessary to disassemble and repair the automatic transmission. Of course, sometimes it is necessary to eliminate some minor issues for inspection and maintenance. Therefore, the disassembly and assembly of the gearbox are crucial. If not careful, the gearbox may be damaged during the disassembly process. In this way, the entire process of disassembling and assembling the gearbox is summarized as follows:

自动变速箱维修

Automatic transmission maintenance

1.各种准备拆卸过程所需的工具小盒零件，然后在干净平坦的工作台上拆卸变速箱。

1. Prepare various tools and small box parts required for the disassembly process, and then disassemble the gearbox on a clean and flat workbench.

2.拆卸应从前油泵开始，从前到后，从外到内开始，并随时进行记录。

2. Disassembly should start from the front oil pump, from front to back, and from outside to inside, and be recorded at any time.

3.大多数自动变速箱均由铝合金制成。拆卸时，禁止使用撬棍和铁工具直接撞击。

Most automatic transmissions are made of aluminum alloy. When disassembling, it is forbidden to use pry bars and iron tools to directly impact.

4.拆卸液压控制阀体时要小心。分离上阀体和下阀体时，请防止球和止动环掉落在地面上，并准确记住各部分的正确位置。

4. Be careful when disassembling the hydraulic control valve body. When separating the upper and lower valve bodies, please prevent the ball and stop ring from falling onto the ground and accurately remember the correct positions of each part.

5.拆卸单向离合器时，必须注意正确的安装方向。 安装时，不得反转。

When disassembling the one-way clutch, it is necessary to pay attention to the correct installation direction. During installation, do not reverse.

6.拆卸零件后，用煤油清洗零件，并用空气压缩机或其他低压压缩空气设备干燥。请勿使用棉纱或其他容易去除纤维的擦拭阀零件。

After disassembling the parts, clean them with kerosene and dry them with an air compressor or other low-pressure compressed air equipment. Do not use cotton yarn or other easily removable fiber wiping valve parts.

7.原则上，拆卸后应更换底板上的O形圈等易碎部件，并且不应再使用诸如老化，变形和磨损之类的易碎部件。

7. In principle, fragile parts such as O-rings on the bottom plate should be replaced after disassembly, and fragile parts such as aging, deformation, and wear should not be used again.

8.应将新的离合器盘和制动盘浸入变速箱油中2小时，直到可以注满足够的油为止。

8. The new clutch and brake discs should be immersed in transmission oil for 2 hours until sufficient oil can be filled.

9.组装阀芯，活塞，密封件等时，应涂上变速箱油。

When assembling valve cores, pistons, seals, etc., transmission oil should be applied.

10.组装时，请严格按照规定的扭矩拧紧每个组件的螺钉。

10. When assembling, please tighten the screws of each component strictly according to the specified torque.
