The cylinder is the heat exchanger used to cool and warm your auto trans fluid. The leak may be from the heat exchanger itself, one of its connections, a frost plug behind it, or the head gasket directly above it. You may have to loosen its mounts and pull it away from the engine, without undoing its coolant connections (if possible) to see where the coolant is coming from.

I would check the acidity of the antifreeze, and if it is slightly high then change it, flush the cooling system, and add a large bottle of BarsLeak at the same time. Use BarsLeak, and nothing else, as you want the soluble oil that is found only in that particular brand.

If you do not have a test kit for acidity, use a volt meter and insert one probe in the radiator so it only contacts the coolant, and then ground the other to the block. If you get any electrical readings at all, change the coolant.

Old coolant, or any of the orange crap that is over 6 months old, will develop an electrical charge that will cause very cold coolant to weep as it seeks a neutral electrical source.

Old coolant can also "errode" cast iron engine parts. especially sleeves in wet sleeve applications. more reading here.

Loose hose connections sometimes won't show up untill it's really cold outside. Have you checked them all?
