I had the trans flushed about 15k miles ago (currently at 103k) and assumed everything was OK. Occasionally it would stay in 2nd gear for what seemed to be a longer than normal time. Today I stopped procrastinating and crawled underneath to check it. 1.75 quarts LOW. No leaks were visible.

I think what happened was that they flushed and filled the trans with the VX turned off. Should probably be done while running (in Park) like the manual says when adding fluid. Just something to be aware of for those contemplating a trans flush. My $.02.
