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. Fault performance
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. Transmission fault analysis
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. 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" 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.
