Engine coolant in transmission.

Appears there is a radiator problem where coolant is mixing with tranny fluid cooler inside the radiator. The radiator will have to be replaced. And it is a bitch. If I remember correctly, the AC system has to be evacuated, the power steering cooler removed, hard to get to fittings removed. The transmission holds about 12 or more quarts of fluid and dropping the pan only removes about 7.5 quarts, so the rest will have to be removed from the tranny. The valve body on the tranny is easy enough to remove but it is electronic. Meaning a little static electricity discharge will result in a 1300 buck part replacement. This is a job for a good shop which warrants it's repairs. I.E. dealership.
