I don't believe so. I do know that for the 4.6L 2V, the Romeo and Windsor engines were different from each other BUT internal parts were completely interchangeable from Day 1 until the end of production, so long as you had parts for a Romeo or a Windsor, whichever you were working on. Main differences I can think of were heads, crankshaft, main caps and bearings but there were some others.
Most '90s engines were back spec'd to 5W-20 in the early '00s, don't remember exactly when. No correlation to any design changes, I remember that distinctly.
4R70W can be a stout transmission. I've seen several over 500k on the original fluid and filter. In my experience what kills them is a broken accumulator spring for gears 1-2, at first it would manifest itself as a slightly rough shift from 1-2 but quite quickly it would just burn up the clutches. Most people first noticed the issue when they went to accelerate from a stop and the truck didn't budge, at that point the trans was done.
These springs seemed to be worst in the late '90s transmissions, I never saw a 2000+ unit have an issue.
A few earlier ones also had issues, they were originally filled with Mercon but were then back spec'd to Mercon V, and a few were serviced with Mercon V and then later switched BACK to Mercon. Clutches would pretty much disentigrate in a few thousand miles. Similar to the 6R60/6R75/6R80 with Mercon SP.
I'd go so far as to argue that the 4R70W/4R100 is one of the best light truck transmissions out there, period. If I could only have one vehicle it would be a F-150 with a 5.4 and a 4R70W actually it'd be a 3/4 ton Dodge pickup with a slant six and an NP435 but you get the point.
