Tranny cooler
I have a 2011 Rubi with an auto, and I keep hearing that you need to put a cooler on the auto so it won't overheat. Any suggestions as to which one is best, and if it is a difficult install.

I have a 2010 Rubi, modified and wheel it and have never overheated. I did get the "idiot light" installed through a recall notice but it has never gone off on me. I think most people that have had overheating issues are towing a lot or wheeling in 4-hi, neither which i do. Turning off overdrive seems to help from what I've read.
There are several threads here that discuss the aftermarket cooler recommendation and even install notes. here is one that talks about the B&M Cooler

Had the idiot light turn on for me like 4 days after having the TSB for it handled. I was attempting to make some runs up Blow Sand out at Ocotillo Wells after installing my kit and tires. All I did was pull over and turn the jeep off for like 5 minutes and it went off and only came on during those attempts. Yes I was in 4 HI. Never thought about turning on the overdrive though....might've helped a bit.

Blow sand isn't a very long\steep sand hill, but the whoops section at the bottom make it tough to get a good run at it, especially if there are quads in the way.
Anyways, I think a trans cooler is an inexpensive mod that could save you lots of time and money

With my kit and those dirt logic shocks I wasn't being too afraid of the skinny peddle haha. It might have been Devil's Slide, I get 'em confused. The longer hill was the one the tranny light came on and the shorter hill with the big whoops is where I broke the trac-bar bracket off the rear axle due to lazy welds (my bad entirely). I would do it if your going to be doing the highspeed stuff, never had issues just doing trails and highway though.

I wheel very frequently and also have a 2 door auto. I have never had an overheating problem and I run the jeep all day and even competed in a 3 mile race course last weekend in 4h and never over heated. Got fourth place tho....:(

I was wheeling up a steep dirt hill in 4Hi drive (auto) and had the light come on. I switched out of drive to 4hi 2nd and the problem went away. Give it a try next time. It keeps the rpm's up higher thus more circulation and less heat.
