The oil change gearbox of the cycle machine is broken?Disadvantages of changing gearbox oil in cycle machine

A friend said that the oil change gearbox of his car's cycle machine was broken. What is going on? I asked carefully. It turned out that his car had been driving for several years, and the gearbox oil had not been changed after more than ten kilometers. He went to a black-hearted repair shop and gave him a cycle engine oil change. It didn't take long for the gearbox to break down.

For cars that have been used for a long time and have a long driving range, it is inevitable that there will be impurities in the gearbox. These impurities will stick to the torque converter, the hydraulic valve body module oil passage or deposit in the oil along with the flow of the gearbox oil. In the bottom shell and gearbox filter element, the longer the time, the more accumulation. If you change the oil with a circulating machine, although the impurities can be removed, these impurities will flow along the pipeline with the transmission oil, which will block the torque converter, hydraulic valve body, gearbox filter and other components, causing oil to pass. Failures such as poor flow, stuck solenoid valves, etc. occur.

The disadvantage of changing the transmission oil of the cycle machine is that it consumes a lot of transmission oil, which is twice as much as the traditional manual replacement. The cost is high, the relative replacement cost is higher, and the profit is high. This is that some repair shops will use it desperately. Reasons for the oil change of the circulating machine. Therefore, it is recommended that when changing the gearbox oil, you should choose the replacement method according to the situation of the car. Under normal circumstances, the correct use of the circulating engine to change the oil will not damage the gearbox.The automatic gearbox is more recommended to use a circulating machine to change the oil, after all, the oil change rate is high and the effect is good.
