Automatic transmissions have been widely known, including AT, DSG, CVT, etc. Although manufacturers have introduced maintenance-free policies in recent years, they do not need to change automatic transmission oil for life, which means they are comfortable with their own gearboxes, although they will ensure that there will be no problems. However, in the actual use of the car owners, there will still be such an abnormal phenomenon. Xiaobian will briefly analyze the causes of the automatic transmission frustration and abnormal noise.

Solenoid valve damage

Because the shifting solenoid valve or the pressure solenoid valve is damaged, the vehicle is frustrated. It can be imagined that if the hydraulic solenoid valve is damaged, the oil pressure will be too low or too high, so the speed of the clutch and brake combination will naturally have a shock. Or a sense of lag. Similarly, the shifting solenoid valve is stuck, and the effect is more direct and obvious. It will make the clutch not separate when it is quickly separated. The quick combination does not combine, resulting in power interruption, which makes the owner feel frustrated.

 

 

For example: 1 block up 2nd gear, 2nd gear up 3rd gear, everything is normal, other gears are normal, 3rd gear up 4th gear is frustrated, then the cause of the fault is very obvious, it is likely to be the clutch for 4th gear or The brake is slipped. Of course, the solenoid valve should be eliminated first, because the solenoid valve is easy to measure after removing the oil pan. The ablation of the clutch will not only cause the shift to frustrate, but naturally it will cause the driving to be weak. The rubbed debris will also contaminate the transmission oil, which will further aggravate the condition!

 

 

Transmission oil is not regularly replaced

Someone will ask what is the relationship between gearbox oil and frustration? The relationship is actually too great. If the automatic transmission is not maintained for a long time, the performance of the transmission oil performance will be greatly reduced, such as lubricity, viscosity and oil temperature stability, especially the oil temperature of the automatic transmission oil. In the case that the radiator is too dirty and the heat is not dissipated, the computer will enter the emergency operation mode after the high temperature is detected, and the forced upshift (locking, locking a certain gear), there will be a “dry” throttle vehicle running. If you don't move, there is a drag and feel, and when the oil temperature exceeds 135°, it will cause great damage to the friction plate clutch plate.

 

The automatic speed box maintenance expert pointed out that the automatic transmission is easy to operate, so it has become the first choice of many people. However, the fly in the ointment is that the automatic transmission is difficult to repair and the maintenance cost is high, and it takes tens or even ten to change a new transmission. 10,000, often makes it difficult for car owners to compliment. In fact, if we regularly check and maintain the automatic transmission, we can also achieve the effect of reducing the probability of failure.
