I can't imagine that the 68RFE trans tuning would be a whole lot different for any customer. Wondering if you have a transmission issue going on, as I've seen no other complaints of a harsh down shifts with Rays warp tuning? Are you just referring to the normal more aggressive tow haul down shifts. I know alot of people don't like the feel of those, even completely stock, but they are harmless as well.
