trans cooler
So I got the hot oil light tonight & figure I should get a transmission cooler so I don't have to post one of those crispy jeep pictures. So my question is how easy are the after market coolers to install?

I'm on my phone right now and the search is a pain. But you can find a couple write-ups and kits browsing the forum. If I find any of those I'll add to this post.

This is the one I followed. It works awesome. I've never had a "hot trans" light, but wheeling through the las Vegas desert all the time, I figured I should have it. And for around $70 there's no reason not to do it.

Transmission Cooler
On my 09 JKU Rubicon auto trans, I installed a Derale Tube/Fin 17" long cooler on the rail just in front of the radiator. The low profile of the cooler does not restrict airflow across the radiator.
The fins on the tube extend inside to help dissipate heat. The big advantages I found is, holds 28 oz more trans fluid, no restriction of air flow to radiator/condenser. I plumbed it in series with the trans oil return line.
In Arizona, during summer, the pan temperature neve got above 200 deg F. Tube cooler temp was 144 degs. Average pan temp in milder weather was 174 degs.
I'm using a laser thermometer.
Cost of cooler $67.00 plus shipping.

The picture shows what the fluid level should be at the various temps shown.
