Looking for a good external transmission cooler
My OEM radiator blew a leak, right where all the '13 and up JK's have been having this issue.
My rig is just over 3 years so they won't warranty the radiator even though I'm under 36,000 miles.
So I'm taking the opportunity to upgrade my radiator, this time to an aluminum tank (Griffin). The issue is, my '13 JKUR is automatic transmission and therefore (I'm told) I need to add an external trans cooler.
I'm going to be stuffing it between the radiator and grille.
I'm trying to narrow down the list of cooler possibilities and would appreciate guidance from anyone who has experience with this kind of mod. I hear there are kits out there for JK's but I really don't know where to start.
At summit racing there are tons of coolers but I don't know which ones will fit in the space between grille and rad and which ones work best hooking up to a jk radiator. When I add 'JK' to my search string, it returns only OEM trans coolers, which aren't external like I need. I called them up and they weren't too much help until I can provide them with the dimensions I'm working with. I'm at work so I can't measure but I imagine somebody here might be able to help me narrow my search.
TIA!

Take a close look at your JK. There is already an external transmission cooler. It's the first thing you see when you look through the grille.
All JK automatics have external coolers. The 2012+ JKs have a much better cooler that is larger, and better located than the earlier JKs.

You were misinformed.

Now, it's possible the new radiator interferes with the OEM external cooler's piping, and that is what they are referring to.
Have you looked at your own JK yet?

The radiator is behind it. (Had to change mine a while back)
I have been thinking of adding an additional trans cooler myself. My JK has 203K miles on it and I think the transmission could use all the help I can provide.
