The rubber hoses that connect the hard lines to the radiator are notorious for becoming brittle with age and breaking/leaking. I would check the lines, replace if needed, fill her with fluid and see if that does the trick. Way cheapee than their "options". Good luck.
For sure not a hose, I had those replaced last year when one blew on me. But they dropped the pan and inspected the fluid which contained a lot of debris from the transmission itself which had new fluid installed last year with the new hoses as well. They dropped it after looking at the fluid and verified the problems free of charge since it was unfixable.
