That is probably the case but, having said that, when Ford brought out its new family of transmissions (developed jointly with GM for $1.4 billion) they said NOT towable flat - but GM said theirs were. I had wanted to buy a Lincoln MKX to replace my Colorado so I was really PO'd because I read a tech article in which a Ford guru explained the new transmissions and how one little change made them towable flat. I called Ford and got no where. Eventually someone got to the right level and they issued supplements. If not for that screwup I would likely have had the Lincoln instead of the much heavier Tahoe LTZ. I should say though, the Tahoe was a very good vehicle and great for towing when I had a DP, and then less desirable when I downsized to a Kodiak, and now out of the question with an E450.
Does yours have the 6F35 transmission?
