Very few vehicles made don't seep slightly from the cooler line hose to metal junction......those of us in the North (you, me) will see it more often in cold temperatures.

The aluminum tubes shrink slightly at the barb joint and because it is cold, trans pressure is elevated.....a cold seep is the result.

You can replace the lines, but the seep will return in about two seasons.

Degrease it and see how severe the seepage is.....you might be looking at two years of accumulation.

The lines leak at the hose to tube interface, known as a 'barb', not where the tubes meet the trans or cooler at the radiator.....there are 'O' rings at those points but very rarely leak unless mishandled at some point.

The crimp at the barb is not serviceable and there are no 'O' rings at that point.
