In modern radiators, the primary trans cooler was a tank within one of the radiator tanks, and the seams in the cooler tank tend to spring a leak before the radiator tank does. It is not an uncommon occurence - even in late model vehicles.

I've not cut one of the Packard external coolers apart to inspect it, but thought it used a convoluted piece of tubing inside the tank to carry the ATF. While I suppose the tubing could develop leak, in due time, I've not had that happen with any of my three running cars, but will check the cooler before I fire any of 'em up again.
