atf

Has anyone used a fluid extractor through the transmission dip stick as part of the ATF change? I have this extractor device from Griots in my garage that I used years ago with an older Benz for certain fluid changes. I am completely aware of the multiple drain and fills recommended for ATF...

First, let me say that I am fairly new to working on cars/trucks. I have been changing my oil for a while now, and can do really basic stuff. I have never replaced the ATF in a vehichle before, so please bear with me. I have it in my mind that changing ATF is/should be like changing the engine...
