With the increasing popularity of automatic models, the frequency of maintenance of automatic transmissions is constantly increasing. Industry experts pointed out that most vehicle owners are not aware of how to properly maintain and repair automatic transmissions. Often until maintenance is required, it is found that its maintenance costs are higher than the repair of the engine. Misunderstanding 1: No need to change oil Many owners did not develop the awareness of replacing the automatic transmission oil. The replacement of inferior oils and non-per-model oil changes can also result in "short-lived" automatic transmissions. Misunderstanding 2: metamorphose change The replacement period of the automatic transmission oil is based on the number of kilometers traveled or the time of use. If the vehicle manual is not indicated, the mileage is changed from 60,000 to 80,000 kilometers. Misunderstanding 3: Two ways to change oil The “hands-over†operation is convenient and time-consuming. The disadvantage is that the oil change is not complete. Only one quarter to one-third of the old oil can be released, which is about 4 liters. The whole process of “machine change†takes about 1 hour, requiring about 12 liters of oil. The advantage of this type of oil change is that the oil change is relatively thorough and can release more than 85% of the old oil. It is worth noting that both oil change methods are performed with the engine starting. Replacement of the automatic transmission fluid must be under the condition of a hot car during the operation. Before the replacement, it should be driven for more than 20 minutes, and the cold oil cannot be changed. To start the engine when changing the oil, shift the gears from P block to N, D, L1, L2 and other gears, and then start to change the oil.
