I dropped the pan on the tranny and replaced the filter today. I succeeded in making a pretty good mess. I laid out one of the wife's old towels underneath will the pan on top and that took care of most of the mess. Also getting the old seal out of the pump tube was a bear. Just an FYI use a socket to drive the new one in the tube because it's a tight fit. It took 4 quarts exactly to bring the level to the full mark.
