If the fluid hasn't been changed for 75k or more, forget it.
Everytime I've done this, the tranny junked out soon thereafter.

All A/T's seem to react adversely to a fluid change (flush), after being neglected for a long period of time.
Some people dismiss this as urban legend. I know better from experience. It's happened to me on two vehicles - a Chrysler and a GM. Both had low miles, but had been neglected.
I've heard all kinds of theories. One of the more interesting ones is that the new ATF "rejuvinates" old brittle seals and gaskets, causing them to fail. The old ATF is supposedly more compatible to the system as a whole.
Use your best judgement, but be careful...

The tranny hyd. pump does it all.
The line to the tranny cooler inside the rad is disconnected and the new fluid container is spliced in line with the cooler.
The engine is started and the old fluid displaces the new in the container and the new is pumped (via the cars tranny) into the system.
I had this done on my EA82T 3 speed wagon with no ill effects, the shifting seemed to smooth out but my problem was the governor wanted cleaned and deburred.
The idea is that the torque converter holds several quarts of fluid and to change all of the fluid is better than changing just the half that is in the pan. Would you change only half your oil?
The filter (under the pan) is just a fine mesh screen and can be cleaned with compressed air and kerosene.
