That is true if the torque converter was locked.
I believe the 6R140 locks in all gears (although 1st only in M mode I believe) and stays locked to 900 RPM. I suspect the 10R140 will have similar programming. Of course... we'll see!
Yes, it will lock at lower rpms where it is creating much less power than it does at peak(5,500 rpm). However, in order for it to lock in 5th at peak power, the truck will have to be traveling at 96 mph. And if this 2020 truck is like all Fords I have owned, it will hit its governor at 95 mph. This is why I said any gear past 4th will put you at a speed over the truck's governed speed to be locked at peak power.
The issue is not that whether it locks in a certain gear or not, it is the rpm it has to lock at for peak power.
