Regret for changing the transmission oil of the cycle machine?Circulator oil change damages the gearbox

The gearbox oil change of the cycle machine is by adding new oil while sucking the old and new mixed oil. When adding new oil, the old oil is pushed out by pressure. The whole process is automatically operated, the operation process is simple, the oil change rate is high, and it can reach The effect of the complete replacement, but there are also friends who have said that they regretted changing the transmission oil of the cycle machine. What is going on?

Some car owners said that the oil change of the cycle machine would damage the gearbox, and regret using the cycle machine to change the transmission oil. In fact, using the cycle machine to change the transmission oil will not harm the gearbox, but the cycle machine replacement will be compared to the traditional manual replacement of the transmission oil. It consumes more fuel and is more expensive. The manual gearbox has a simple structure and does not require high gearbox oil. Although manual replacement cannot be completely replaced, it is economical. The structure of automatic transmission is more complicated. The requirements are high. Once the oil quality is not good, problems are prone to occur. The cycle machine can replace the transmission oil more thoroughly, which can extend the maintenance period of the transmission oil.

However, for high-kilometer automatic transmissions, it is not recommended to use the cycle machine to change the transmission oil, because there are certain risks. If the cycle machine is used to change the oil, although it can be stuck in the hydraulic torque converter, hydraulic valve body module oil Impurities deposited in the oil pan and gearbox filter element are removed, but these impurities will flow with the pipeline and block the torque converter, hydraulic valve body, gearbox filter and other components, resulting in poor oil flow. , Solenoid valve stuck and other faults occur.

It must be said that the friend who regretted changing the transmission oil of the cycle machine may be that the car is blocked, the oil is not smooth, and the solenoid valve is stuck. The gearbox oil needs to be replaced in time, but the replacement method needs to be selected according to the specific use of the car and the gearbox model, so as to ensure the normal operation of the gearbox.
