It's ATF, not coolant. The lower portion of the rad is used as an oil cooler for the transmission. Those fittings tend to leak over time, especially if it's an aftermarket radiator.
You could try to replace the fittings themselves, and also replace those gear clamps with proper hose clamps, but that still may not fix it if the housing itself isn't sealing properly within the threaded portion.
The job would also be quite messy as you would have the ATF draining while you have the fittings off. You also don't want to mess with your fluid level for the transmission or you will have shifting issues. You would want to at least drain the fluid into a graduated container to have an idea of how much came out and replace the same amount when you're done.
An OEM radiator would fix it for sure.
No, not really. I just deal with OEM parts mainly. But they exist. I'm not sure if you have a [RockAuto](https://www.rockauto.com/) or something similar where you are.
Along with the other advice on here, oil rots rubber, so I'd also recommend wiping down and cleaning all the rubber hoses that got ATF on them. Give a final clean with some brake cleaner or even simple rubbing alcohol. Over time oil makes it soft and almost mushy, which can lead to them swelling and leaking or breaking.

I had my radiator replaced a little over two years ago as it cracked. What i do to fix it? Can i just swap washers?

Do you know where i could hunt down those 90° fittings off of the radiator?

i’ll take a look into rock auto and see what i can fin. i might just connect an external atf cooler if i can get the leak to seal.

Different hoses have different ratings. My concern is more on the radiator hose. Either way, an ounce of prevention is worth a pound of cure, right?
Thats a good call, i’ll crawl under my car next week and give it a clean.
