You don’t need to break the bank on this. A simple Hayden 679 Cooler will do the job. Rockauto has them for less than $42.00 (link below). I have one sandwiched between the AC core and the DeWitts rad and my car still doesn’t go over 180* with a 3600 stall FTI converter. I’ve run it both in series with the rad cooler and right now I only use the Hayden as a stand-alone. I could do that since we never get less than mid-70 degree weather. The only thing extra you’ll need, if you’re connecting it in series with the in-radiator ATF cooler, is a # 397 quick-connect coupler, also offered by Hayden. (link below). If you don’t have a H/X intercooler up front, all you need to do is use the included pin fasteners to attach it to the front of the AC condenser core. Simple, cheap and very easy, and works as good (or better) as a fancy stand-alone module with a fan, for which you would have to fab up a bracket or brackets, remove fog lights, etc.

I saw your post about the Hayden Trans Cooler you ran as a standalone. Other then the Hayden Cooler what else is needed to install it as a standalone between the Condenser and radiator and do you have any pics by any chance?

Tag right along, it won't make it to cool, only time you have to worry about it is if you live and drive it in a area that gets below 50s. But the fix to that is to not use it as a standalone and run it inline with the cooler you already have in your radiator. I just need some clarification on the best way to run it as a standalone and possibly some pics.

Hayden 679 trans cooler
This is how I had it on the stock rad. It’s pretty much the same way I have it mounted on the DeWitts rad.
I ran the hoses up through the top and then routed them over to the RH side. Just be careful that they’re not pinched or won’t rub on the top of the rad when you put the plastic rad cap back on.
Here you can see that it fits snug in between the rad and the condenser core.
This is the only picture I can find with the DeWitts rad that shows the hose routing.
