I want to have my transmission serviced. which is better drain or flush on 2006 Dodge Magnum

transmission professionals who I have asked gave me two different opinions. I wonder which is the right advice? I am not having problems, I just want to get it done. And does it make a difference by it being an all wheel drive?

Some are different here as well, I personally like flushing all the fluid and having all fresh fluid and add some BG cleaner then some BG conditioner at the end.
if it is a high miler and the fluid has never been changed I wouldnt recommend changing it because you might get more headaches
