Higher stall will make more heat. if you just tool around town with that lower stall your stock cooler should be ok, but if your going to stall/flash it a lot and close together it might heat the fluid good.I would at least run a deeper pan that will hold 2 to 4 quarts more.
thanks I allready have a deep pan and pom. ill run a external cooler also.

I always decided to run one after I completely fried my transmission. However, I have 2 (yes 2) coolers and I think I may have overdone it. It completely bypasses the radiator but even on the hottest day, my tranny gauge (sender is in the pan) never goes about 170. On a normal day, I'm lucky to hit 140 or 150. Now I am afraid of keeping it too cool. eight

That CAN be a problem ...toooo cool ATF will "kill" some of the stall speed.

I have heard the same thing about being to cool.
The radiator "cooler" is also a HEATER ... in fact lots of later model trans-combos will not operate properly uNtil the ATF is up-to-temp.
The only motor-vehicle-combo I could think-of that you would not want to use a radiator cooler/heater would be a all-out race-car or a towing/RV combo.

Consider synthetic transmission fluid also! Heat is the #1 source of problems for an automatic trans. Synthetics hold up much better against heat and potential breakdown. Amsoil Universal trans fluid. I've been using their Universal trans fluid in my 2004 Dodge diesel dually that I tow my race car trailer with and their SuperShift in my race car 904. My trans builder said to keep using whatever I have because it protects very well. Car is race-only, but converter flashes between 5000 and 5400 footbraking, depending on weather and other factors, weighing 3,540+ lbs. Summertime hot-lapping in the late rounds is what concerns me the most and I have an external cooler also, but bypassing the radiator.

The ideal set-up is an oversized/large trans cooler before the "in-tank" cooler that maintains the "running-temp" of the returning fluid to the trans.
Heat is the greatest nemesis of an automatic trans.
And as mentioned, too cool is not ideal either, the fluid is not a consistent temp for operation.
Some car makers now use a thermostatic bypass to help the trans heat up its fluid quicker to running temp......something to think about.
