There is a lot of misunderstanding about the difference between an ATF exchange and an ATF flush. An ATF exchange is when we drain the fluid from the pan and add new fluid, sometimes replacing the filter or gasket if necessary—usually only about half of the fluid is replaced during an exchange. An ATF exchange is not a repair but rather a pre-emptive maintenance procedure. After an ATF exchange the vehicle will usually perform better. An ATF exchange is intended to support OEM service requirements to increase the life expectancy of the vehicle and its parts.
An ATF flush is when we determine that there are deposits inside the transmission that need to be cleaned out, so we push new fluid into the transmission with an ATF flush machine to force out the grimy deposits. During an ATF flush we force pressure or chemicals through the system to rid it of contaminants. At Northern Automatic Grande Prairie we perform both and will be able to advise which is necessary.
