1. check the transmission oil regularly according to the original requirements, replace the transmission oil on time, and use the original designated marked transmission oil.
2.通过放油螺栓放出的油只占总油量的三成左右，这种情况不建议使用变速箱清洗剂。
2. the oil released by the oil drain bolt only accounts for about 30% of the total oil consumption.
3.若彻底更换变速箱油，应配合变速箱油交换机使用变速箱清洗剂。在把旧油放掉之前，将清洗剂倒入变速箱，驱动轮悬空，着车后，通过不断换挡来使清洗剂能够清洗所有内部区域。
3. if you replace the transmission oil thoroughly, you should use the gearbox cleaner with the transmission oil switch. Before the old oil is released, the cleaning agent is poured into the gearbox and the driving wheel is suspended. After the car, the cleaning agent can be cleaned by constant shift to clean all the inner areas.
