If your auto trans cooler failed you could mix coolant with the auto trans fluid but I don’t think that would be pure coolant leaking like it appears in your picture. More like a muddy mess and you’d likely have shifting problems. I think my money is on your heater core lines that run right into the firewall behind the engine and above the transmission.
