If that's what you get in a worse case scenario, you'll be fine. "Normal" ATF temps are usually in the range of 175-200 degrees F. It would have to get to 240 degrees before varnishes would start to occur. Engine overheating wouldn't occur until coolant temperatures get close to 250 degrees in the pressurized system.
If you are still concerned, a more efficient radiator would probably be all you need. As you bring those coolant temps down, the ATF temps should drop as well. Stillen sells the CSF all-aluminum radiator which would likely do the trick at less cost and complication. However, if money isn't figured into the equation, there's nothing bad to say about Griffin.
