How Automatic Transmission Should Repair and Change Oil

From the automotive market survey, it has been found that automatic transmission models are becoming more and more popular, and the frequency of maintenance of automatic transmissions is also increasing. It is also found that most owners are not clear how to properly maintain and repair the automatic transmission. Often until maintenance is required, it is found that its maintenance costs are higher than the repair of the engine. Most people have some misunderstandings in maintenance:

Misunderstanding 1: The change cycle of the automatic transmission oil replacement is based on the number of kilometers traveled or the time of use. If the manual for the vehicle is not indicated, the replacement mileage is replaced by 60,000-80,000 kilometers.

Misunderstanding 2: The two oil change methods are easy to operate and less 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, and it requires about 12 liters of oil. The advantage of this oil change method is that the oil change is relatively thorough, and it 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.

Myth #3: There is no need to change a lot of car owners, and there is no 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. Automatic transmission oils often exist in an overlooked image, and when they are discovered, they realize that the original cost is very high, so it is important to pay attention to the maintenance and maintenance of automatic transmissions.
