1999 Ford Ranger XLT 3.0 160k miles

So I just bought a Ranger. Had to do some initial repairs, including a few O2 sensors, hoses, temp sender and sensors, water pump, thermostat, new cylinder head, head gasket and related gaskets/seals, serpentine belt, etc.

I think when I was tightening the transmission oil cooler line for that goes into the radiator, I cracked the housing accidentally. I noticed a slow drip leak under the car and tried tightening the connections. Thought it was fixed, test drove it for about 30 minutes, then noticed the drip was actually a little worse. That is why I think the housing cracked. The leak is definitely not around the connection piece, it's coming from the bottom of the plastic housing that the cooler is located in.

So I bought new radiator I will put in today. When I was disconnecting the trans lines at the radiator, after draining most of radiator at the petcock, a lot of coolant came out at the trans lines connections. I am not sure any got into the transmission lines. 

I could blow out the trans lines away from the transmission into a bucket, but is there a way to tell if coolant has gotten into the transmission without draining and refilling the entire transmission? I know that can cause other issues and this truck is barely holding on as it is....
