finally did mine.
the maintenance minder never show atf as necessary. i am on 40,000 miles mark. then i realized it should be done at lease once every 2 years.
man, it was DIRTY. lots of deposit at the drain. The only difficult part is to fill it. my plastic tube was too big for my dip stick hole. spilled quite a bit everywhere.
what a difference after change. the change of gear felt a lot smooth now.
