Transmission oil is leaking

Normally if oil or transmission fluid mixes with coolant it will turn milky looking like a milkshake. Your leak must be pretty fresh. from your description that it is coming out of the coolant overflow I am thinking you have a radiator transmission cooler leaking into the cooling system.

You will need a new radiator and possibly all the coolant hoses if they have become soft from the transmission fluid.

In most cases if your getting transmission fluid in the radiator it is cause by a bad transmission cooler that is built into the radiator and the fix is to replace the radiator.

The repair will change in price from where the leak is coming from. If the pan is leaking or the rear seal your looking at $100.00 or less. If the front seal is leaking then around $550.00. The most common leak is the pan gasket. Also if the transmission fluid and filter have not been replaced in the last 30,000 miles and the pan is leaking then I suggest doing this also why the pan is off .

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
