I'm thinking that you are experiencing the torque converter engaging, and you're thinking it's just going into overdrive. That said, I can't speak to whether or not it is shifting as designed from your description. I can definitely tell you that the 4R100 automatic transmission in your Super Duty truck is a little maxed out by the 7.3L Diesel torque and power generated. You didn't mention if the truck is stock, or has any performance modifications -- if you are generating more power with your Diesel than stock, the transmission really can't handle much more. Ford developed the Torque Shift automatic transmission for the 2003 6.0L Diesel specifically because they needed a stronger transmission for their Diesels - that are always increasing in torque and horsepower ratings. The 4R100 - besides being outdated and not as efficient - just was always at its limit with the 7.3L. That said, it is possible indeed that your transmission is showing signs of wear and tear. Dropping the pan and checking for debris and changing the fluid and filter may not be a bad idea, just to assess the condition of the fluid and to see if any metal is on the magnet in the pan, showing possible internal issues.
