Sorry to bring this thread back.
Anyways, I've read through all the posts, and considered taking jibberjabber's advice, but am still unsure whether I should flush or just drain and fill my ATF. Well, my car is at 90k (yes, I know I've waited too long) and the previous owner has never changed or flushed the ATF. My question is, since I've gone so long without a ATF change, should I still just do a drain and fill, or just take it in to the dealer and flush it?
I'm only asking this question because I seem to be the only one who hasn't changed the fluid in such a long time. What do you guys think?

I think a drain/fill is less invasive.

My experience with old crappy cars is once you get over 100K miles, don't flush the trans. I've had cars start slipping at that point.

The radiator cools the ATF fluid. It's the two smaller hoses on the bottom of it, but I don't remember which one is the return.
