That’s not really good news for you. I’d try to get those parts added, or at least that Mach 1 converter.Enfact

One clear instance where the lockup condition will ADD more heat is when and only when it starts slipping. That also happens with all the shifting, as it’s momentarily disengaged and locked cyclically. Just saying. And good luck.
