The radiator has a sticker on it that says "nissens", and made in sweden. Is this the oem radiator for my car?

Definetely coolant leaking. It forms in small puddles on the bottom tray. Where would I look for tranny fluid in this area? On rare occasions, I smell burning tranny fluid, but this could be from anything.

No visible crack on the fitting, just a line of coolant running from it down to the other tranny cooling line.
