Initial startup cooling system troubles

Regarding the possible trans fluid leakage I wondered about that. The water doesn't feel greasy, and I spilled enough of it on the floor when I tried the 2nd drain and refill to dump maybe a quart on the cement! It evaporated like it was all water - no residue on the floor.

I haven't drained the break-in oil but I see no sign of water on the dipstick. I know that's not a perfect way to spot it so I will drain the oil and start over again.
