With the intercooler out of the KJ and going for repair tomorrow, I have a few days to catch up on projects that have been pushed aside. One of those is installing the external transmission cooler.

What I would like to do is connect the external cooler to the factory fittings. That way, if for some reason I ever remove the external cooler, going back to running just the OEM one is plug & play. It also means that if the factory cooler ever dies, upgrading the external unit to handle the load should be equally simple.

The part that isn't clear to me: which fittings to use. I'll need one male and one female quick disconnect compatible with the existing lines and cooler; that much is obvious. But I'm not certain that I'm finding what I need.

So far, the closest I've come is this:

https://www.dormanproducts.com/p-73463-800-723.aspx

That could potentially work for bringing the line to the external cooler (assuming it's the correct item), but leaves me stymied for how to connect back to the OEM unit. And yes, I am aware that this particular item is intended to be fitted to the transmission, but thread adapters might make it usable for what I'm looking to accomplish.

Anyway, if anyone has done this before, please let me know what you've used. Cutting the existing lines and changing the connector types is something I'd prefer to avoid if at all possible.

When I installed my addon cooler, I simply cut the factory hose and used AN fittings. But I don't ever plan on changing the configuration unless something goes wrong.

Would something like this work for what you are trying to do?
Summit Racing has quite a few different kinds of quick disconnect transmission line fittings.

Took a look at those. The Jiffy-Tite ones in particular look nice, but they're pricey.

At the cooler end, I'll probably just do a 3/8" line adapter out to 3/8" barb. That one's easy; I'm just not sure what type of quick disconnects to get for the lines to the OEM cooler.
