All, I did a drain a fill a few months ago in preparation for a complete Steptronic fluid and filter change. I did not have a completely square floor jack stand setup. They may have been off by about a 1/4" between the front and back.
When I went to pull the fill plug today, there was quite a bit of fluid that came out prior to getting ready to pulling the actual drain plug.
As fluid expands when it gets hot, this seems to indicate that perhaps I overfilled the transmission a bit when I did the last drain and fill. Should any fluid have come out at all? As I had read on another posting that it makes sense to measure what you have taken out, this would mean I am about to overfill again.
Should I fill the system to a little less than what I took out and then start the car to warm the transmission and then fill to the point where it is just coming out of the fill plug? This is a real pain in the ass as I am old school and used to having a dip stick to check the tranny.
Suggestions from other AT Steptronic owners is appreciated.

Next question is regarding the old filter vs the new. This is the old filter and it came out with just one of the seals and a plastic flange assembly. The new is showing two seals and a plastic flange assembly. If you look up into the transmission it shows to have another gasket there but I am unsure if it is supposed to stay in there or needs to come out. I took a pick to it and it seems pretty happy to just stay where it is. Does that other gasket need to come out, or does it stay?
