Hard to see from picture. But it is some sort of extended surface heat exchanger. ATF probably flows across horizontaly in 1 or more passes and there would be openings for coolant to cross flow vertically.
But without more details, I would just be guessing even although heat exchange is an area that I
used to know a lot about
Maybe someone has an old rad that they cut open for us
