TheRamChargerMan said:al ya need is the weight of a gall of tranny fluid, and some math.
Yes, the shop manual (real shop manual) I have shows 5-30 psi range for the flow path to the cooler under all conditions. So I'd guess there is an orifice to reduce the pressure down, and it is most likely 5 psi at park/idle, and 30 psi under full throttle/drive conditions.

Mine is for a 79 727, but it has nice color diagrams showing all the flow paths under different conditions, and the pressures for each.
If you need it, I can see what it would take to make some color copies.
