Auto Tranny cooler

Derale 13613, 22,000 gvw plate and fin cooler.

Behind it is a Fluidyne 7 inch puller electric fan run off a derale relay and thermal switch which you can see at the cooler inlet. Works great, purchased it from E-trailer. I used a fuse tap in the empty heated seat slot I believe m9 to run the relay.

The thermal switch comes on at 180 degrees shuts off at 165. Its hot here in central cal and the fan has been working, keeping my tranny fluid nice and cool. Just ordered an aeroforce gauge.

Decided i needed this after driving up a dirt road in the spring. It was 65 degrees outside I was in two wheel driving up a slight incline. I was stopping periodically so my girl could take pictures of wild flowers. Was not going over 10 mph and was stopped 10 mins at a time while she got out. Got the hot oil light.


Picture below, sorry still learning, I removed the ginormous one.

I still need to paint things black, probably this weekend.

Any questions, didnt do the full on install write up because it's pretty much like the others as far as mounting.

Sweet! I have been thinking about installing a Derale 13700 and was wondering if anyone has done something like this.
Did you plumb it inline with the stock cooler or did you totally bypass the stock cooler?
I was thinking of mounting the derale cooler under the body around where my evap can used to be and then using the stock trans cooler as a power steering cooler.

Edit: after looking up the part number I see your cooler is just a radiator. The 13700 has a fan so it can go anywhere and work well when crawling. I am hoping it will perform well if I use it as a stand alone unit and bypass the stock cooler.

Nice set up, but I'm not too crazy about fin coolers because the fins can be easily knocked out of shape/damaged by road debris. I prefer plate-type coolers like B&M which are much more rugged. Otherwise, I like how you have it set up with the fan and switch.

I have a B&M cooler but with no aux. fan. It seems to be doing the job of keeping the temps in check just fine.

I would be afraid to put anyhing "Under" the jeep, especially a fan powered cooler--

I use two aux coolers and have cut the factory cooler (warmer) outta the loop--

My op temp rarely goes over i50 F--

It's a jungle out there-

Nice setup. I used a Hayden cooler spliced in as an auxiliary. Problem fixed, no issues.
