Think my torque converter has a problem? Stalled too high perhaps?

Might have had a failing pump, or internal leakage...VB or piston seals, hard to say. Unfortunately there *are* quite a few things that can go wrong when they do and you'll definitely piss yourself off chasing them if you don't have all of the tools and knowledge (I know, sounds like a been there done that story doesn't it? LOL)
I have a '97 F250 7.3 that I have a switch hooked up to momentarily disable EPC. I basically need this for the 1-2 shift, everything else is GREAT. Truck has 330,000 miles on it. A moderate annoyance but again literally everything else works EXCELLENT. With full pressure it holds under the 40 and 60 hp tunes, without, it flares. Intermediate piston seal must be leaking, I've had the VB down like 6 times did all of the Sonnax fixes and a TransGo kit.
The truck towed a lot prior to me, no aftermarket cooler. I bet heat did it in. But it sucks that all of the friction elements are probably OK but a simple seal failure way inside, is forcing me into a remove and rebuild at some point. And yaaaaa MIGHT as well do everything, while you're in there....
