有人说XX车难修，也有人说XX车保养贵。事实上，用料扎实、配置低调的XX车可能只是不符合很多车友的口味。以今天的汽车为例。事实上，变速箱故障只是因为故障的概率。毕竟里程太多了。，今天就来看看汽车变速箱故障的案例。

Some people say that the XX car is difficult to repair, while others say that the maintenance of the XX car is expensive. In fact, the XX car with solid materials and low-key configuration may just not meet the tastes of many riders. Take today's cars for example. In fact, gearbox failure is only due to the probability of failure. After all, there are too many miles., Today, let's take a look at the case of solving the problem of automobile gearbox.

1、故障表现

1. Fault performance

车子跑着打滑，跟不上速度，加油也没有加速，只看到转速表高高飘落，终于实现了升档。换档时也有强烈的磕磕碰碰感。仪表盘有时会闪烁“雪花”和“S”字样。如果在路边熄火重新启动，故障灯会消失，但有时故障灯会再次出现。

The car skidded, couldn't keep up with the speed, and didn't accelerate when refuelling. I only saw the tachometer falling high and high, and finally realized the upshift. There is also a strong bump when shifting gears. The words "snowflake" and "s" sometimes flash on the instrument panel. If you turn off and restart at the roadside, the fault light will disappear, but sometimes the fault light will reappear.

2、传动故障分析

2. Transmission fault analysis

1.挫败感。主要是阀体异常。仔细看，电磁阀上有厚厚的油泥。电磁阀内部有阀芯，变速箱油太脏，会导致阀芯卡死。阀体内还有精密的阀芯和阀道。空间极小，阀芯来回移动。在杂质进入的过程中，阀道和阀芯容易磨损和沾污，导致变速箱油压无法调节。正常，造成挫折和冲击。

1. Frustration. The main reason is that the valve body is abnormal. Look carefully, there is thick sludge on the solenoid valve. There is a valve core inside the solenoid valve, and the transmission oil is too dirty, which will cause the valve core to jam. There are also precise valve cores and valve channels in the valve body. The space is very small, and the valve core moves back and forth. In the process of impurities entering, the valve channel and valve core are easy to be worn and contaminated, resulting in the failure to adjust the transmission oil pressure. Normal, causing frustration and impact.

2.滑倒。通常是由于离合器内部的摩擦片损坏造成的。我们可以清楚地看到，这套摩擦片已经被高温烧坏了，天黑了。换档时离合器片不能保持和释放压力。正常情况下，离合器是靠油压推高的，但现在明显抓不住，导致车辆加速时动力不足，档位难以升起，打滑。

2. Slip. It is usually caused by the damage of the friction plate inside the clutch. We can clearly see that this set of friction plates has been burned out by high temperature and it is dark. The clutch plates cannot maintain and release pressure during gear shifting. Under normal circumstances, the clutch is pushed up by oil pressure, but now it is obviously unable to grasp, resulting in insufficient power when the vehicle accelerates, difficult to raise the gear, and slipping.

3、“Snowflake”和“S”故障灯闪烁。这是汽车故障的一种特殊现象。济南自动变速器维修厂家认为，这种故障灯提示并不是表面上通常所说的空调温度方面的外围问题，而是对变速器故障的特殊反应。严格来说，只是控制单元的信号紊乱造成的。这是整体设计的一个缺陷。

3. "Snowflake" and "s" fault lights flash. This is a special phenomenon of car failure. Jinan automatic transmission maintenance manufacturer believes that this kind of fault light prompt is not the peripheral problem of the air conditioning temperature usually mentioned on the surface, but a special response to the transmission fault. Strictly speaking, it is only caused by the signal disorder of the control unit. This is a defect of the overall design.

任何一种问题如果被忽视，都可能发展成各种各样的问题。各种问题的维护成本自然就提高了。在此提醒车友们，如果有变速箱故障的前兆，一定要抓住机会进行处理。有的可以通过换油改善，有的需要的维修机构来处理。更多相关内容就来网站http://www.jnbsx.com咨询吧！

If any kind of problem is ignored, it may develop into various problems. The maintenance cost of various problems naturally increases. I would like to remind motorists that if there is a precursor of gearbox failure, they must seize the opportunity to deal with it. Some can be improved by changing oil, and some need professional maintenance agencies to deal with it. Come to the website for more relevant content http://www.jnbsx.com Consult!
