It looks like a liquid-to-liquid type heat exchanger. I would assume (you could follow the tubes...) that the visible tubes are an engine coolant loop, and the trans fluid circulates internally much like the oil cooler on the SRT 6.4 Hemi. That will heat the trans up quicker when you first start driving, and then shed heat the other way when the transmission is under a heavy load.
And tow it will! My boat only weighs about 7500 pounds with the trailer and all, so it really won't have to work very hard, eh?

Show off.
An 8500-lb Sportsman trailer sure made my 4.7 work noticeably! It did fine, but that's about the limit (practically speaking- it could safely go a little heavier if the driver were more patient) with my rig right now. Of course it doesn't have a great rear end ratio for towing either.
