Hi Dennis, no they didn't drop the pan, I wish they had but I will do this myself after I finish the 'trips this summer' to get ready for the winter.
Differences, much smoother both in sound and in feel when shifting up and down. Quicker as well which makes me think the previous fluid was pretty much 'cooked'. The Chilton manual
shows trans fluid lifespan dramatically reduced with heat.
I did just do 4,000 miles to southern California (Joshua Tree to Death Valley) and back and it ran well. Still have shift issues with mountain passes, really long hills but noticed that if you run gently up and don't shift into overdrive until you have gone downhill for a few miles everything runs flawlessly. Some of the hills and passes are pretty big for a 4 cylinder auto.
