In fact, most of them do not. So in order to change the fluid, the transmission pan must be removed so that the old fluid can drain out. With the pan removed, the transmission filter or screen can be replaced. The pan is then reattached using a new pan gasket, and the transmission can be refilled with new automatic transmission fluid.
This can be quite a messy process as the fluid drains pretty erratically when the pan is removed. This is the method that most dealerships and repair shops use today because it requires much less manual effort.
The machine either acts like a vacuum and sucks out all the old fluid or pumps in new fluid as the transmission itself pumps out all the old fluid. Either way, the fluid is removed through the use of force or pressure and the transmission is refilled during the same process. Flushing is typically faster and less messy than a traditional change.
However, there is much debate about which method is better for your transmission. There are pros and cons to both methods, and mechanics still disagree about which method you should ultimately choose. Even with this debate, there are certain aspects of each that most everyone agrees on and you can use these facts to help you decide which is right for your car. A traditional change does not actually remove all the old fluid from the system.
Gravity is simply not enough to remove it because it sits inside other internal parts. A transmission fluid flush, however, uses pressure to push all the old transmission fluid out of the system as it is refilled with new fluid. It is more of a fluid exchange than a drain and refill. For this reason, many mechanics recommend performing a second fluid change within 10, miles of the first. This helps to make sure that the fluid and contaminants are fully removed from the transmission and it is refilled with fresh fluid.
If a flush is performed, there is no need to perform a second one so soon. Another big point of debate between these two methods is the amount of stress that each places on your transmission system. With a regular change, there is little to no stress placed on the system. The fluid simply drains out due to gravity, and there is no pressure present to force tiny particles or metal shavings into places they should not go. A flush, on the other hand, uses pressure to force the fluid out of the system.
Many people argue that this pressure can force tiny particles and contaminants into parts of the transmission where they should not be. This can cause terrible consequences like improper shifting, overheating, slipping, or even total failure. Many of these people also argue that flushes can cause a transmission to leak because the seals inside the transmission are not made to withstand that much pressure. This can cause the seals to break or burst and fluid to leak.
Conversely, those who are fans of the transmission flush contend that the pressure actually cleans the internal parts of the transmission. Is the information useful? Jai Deva Oil Co.
