Tow/haul actually makes the transmission want to downshift more quickly (though not so often that the torque converter overheats the tranny fluid), and locks out overdrive (generally) so you shouldn't see it wanting to stay in a high great too long while in T/H.
I don't know if I agree with that but I don't have the exact transmission the OP does either. Tow/haul usually makes the transmission want to shift
less often. Sometimes that means staying in a higher gear with the torque converter locked and the engine lugging some. The unlocked torque converter during shifts is what makes all of the heat.
