I would prefer to do it this way as its easier to get at and doesn't break the seal at the hull, however I can imagine there is some water lying in the transmission cooler lines.

Which method is recommended?
I suspect that the transmission cooler is downstream from the pump on your boat. Attaching to the RW inlet wouldn't bypass the cooler.

As to the transmission cooler lines, there are none that contain water. Transmission oil is circulated through the cooler. The water path out of the RW pump through the cooler is just a straight 1 1/4 inch shot. The cooler is vertical...should self-drain promptly.
