well my truck is pretty heavy,so likely a bit latter than a stock/lighter f250 of course.about 1500-2k rpm when empty,on flat ground.if much latter than 2k,then im either taking off pretty hard to scoot out safely in traffic,or iv got a load on.
you've got to wiggle them wires.you know right now,since she's shifting her normal,that the wires are joined.it's when the brake in wire due to vibration causes your issue.-the theory anyway since it's intermittent.

holy crap!!! mine NEVER shifts under 2k rpm unless i am CRAWLING along in traffic. even driving easy and civilized it does not shift until after 2k rpm. just to keep up with the flow of traffic i usually shift at about 2500 rpm.

The only time I use a volt meter on that critter is to set it up. After that, its the test drive and twist method.
(Test drive to find the shift points. Twist the TPS to make the shift points to your liking.)
Sometimes the stock specs suck.

correct...
Thanks for backing me up on that... Any clues to a possible solution for me... I'm baffled... Ready to install an aftermarket tach somehow, and see how many rpms I'm spinning to move anywhere... Does that stupid electronic od sensor need to be wired on the side if the trans. To give it dome ***** even if I'm manually shifting? That seems dumb to me...
