Yes, you can cool the tranny fluid too much. If you don't have a thermostat it can keep the ATF too cold and not burn off the water. That is why OEM putters don't lock the converter up for several miles. They want the ATF to come up to temp.
Good answer here. I would recommend installing a trans temp gauge so you can see what temps you are running at both empty and when towing, then you can make an assessment about how large of an external cooler you want to add or if you even need one.
Theoretically, you can't have a cooler that's too large when towing, but as Peeps pointed out, you don't what the transmission to stay tool cool when not towing, which is most of the time for most of us.
