Ron,
Our 2005 (built in the fall of 2004) E450 based Itasca Class C has the Ford 5R110 5-speed (6 actual ratios, internally) computer controlled transmission in it, so I think that Ford probably started using it from 2005 models onward - at least in E450 cutaways.
By the way, when our original 5R110 transmission unexpectedly failed at just over 61K miles, I had a heavy duty remanufactured version of it installed. For some reason this HD version from day one seems to shift much smoother and positively than the original did.
