I don't know what beginning year "new" refers to regarding the F250, F550, F650, and F750 models, but as I understand it the really big change to the 5-speed (with 6 internal ratios available under certain temperature conditions) computer controlled 5R110 TorqShift transmisson with the Tow/Haul mode was first introduced in the E-Series vans in model 2005. Some years after 2005 the E-Series vans were fitted with a transmission that uses 6-speeds all the time.
The 6 speed 6R140 transmission introduced to the E series in I think 2016 (but used in the F series for some years previously) is not really closely related to the 5R110. It has completely different gear ratios, and the six ratios are nicely and evenly spaced. I would consider it as much an upgrade from the 5R110 as it was over the 4R100, maybe even more so.
The 4R100 (older four speed) and 5R110 appear to be quite similar internally, the added gear being between first and second on the four speed but otherwise having the same gear ratios. The control computer for the 5 speed is in my opinion the more important improvement. Both have a rather annoyingly large gap between the top two ratios that are most used for highway driving.
