If the automatic transmission enters the water, the oil will appear milky. There are generally two cases of water intake. The engine coolant enters the automatic transmission through the radiator; there is rainwater or car wash water that enters through the automatic transmission vent hole and automatically shifts. After the tank is filled with water, the failure of the vehicle will not be displayed for the first time, so it is necessary to observe the transmission oil from time to time
A large error in the oil level will also cause a large amount of foam in the tank oil. When the oil level is too low, the oil pump will suck in air, which will easily cause the oil and air to mix; if the oil level is too high, it will make the planetary gears and The other rotating parts were immersed in the QJ Gearbox, and the oil stirring phenomenon occurred. Whether it is too high or too low, it will cause the automatic transmission oil to deteriorate and thus malfunction.
If the ordinary metal parts are badly worn, there will be metal impurities in the QJ Gearbox oil, because there are a lot of metal fragments in the transmission oil, generally because the metal parts in the transmission are seriously worn, such as the middle of the transmission Shafts, bearings, clutch steel plates, clutch cups, etc., these mixed with oil will cause deterioration
