Same with any fluid,or most metals even, They expand when heated. How much? That's what I wanted Roger to do for us. Find the range difference between hot & cold. I'd think the oil in the pan runs cooler than what's in the convertor, but depending on load and for how long the load is applied would determine the total growth.
