Is it better to replace the transmission oil circulation machine or gravity?

First of all, the gravity oil change method is similar to the oil change method, using gravity to let the transmission oil flow out and replace it with new transmission oil. Although this method is simple to operate and low in cost, due to the complex internal structure of the gearbox, it is difficult to completely drain the old oil, so only about 60% of the new oil can be replaced. The oil change was not thorough enough.

In contrast, the cycle machine oil change method uses a cycle machine for transmission oil changes. Although the steps are slightly more, the transmission oil can be completely and completely replaced. First, the old oil is drained out by gravity, and then the remaining old oil and new oil are circulated and replaced with the help of a circulation machine. This method can replace about 90% of the transmission oil. Although it requires more transmission oil and costs more, the effect is more thorough.

Transmission oil replacement is very important for your car. It cleans and lubricates the gear system, ensuring long-lasting transmission use and smoother shifting. Failure to replace the transmission oil for a long time will cause difficulty in operation and cause severe wear to the internal gear set of the transmission, thereby increasing the risk of damage.

In addition, a gearbox that has been used for a long time will accumulate many impurities, resulting in increased idle speed and increased fuel consumption. Therefore, after replacing the transmission oil, the performance of the car will be significantly improved, making it more fuel-efficient and easier to use.
