I never considered that and it's a good point. Don't 700R4's have a lockup converter? It would be interesting to know (1) does an overdrive trans run cooler or hotter than a non-overdrive [or is there no big difference] and (2) does the lockup converter make it run cooler because it's not "squeezing" the fluid?
