Ripp Supercharger and Transmission cooler
 

Need help with my 2013 Rubicon Penstar 3.6L. with max tow package. I recently purchased a Moby-1 XTR trailer...loaded weight about 3,000 lbs. Installed a Ripp supercharger to help with towing. Problem now is HOT OIL!!! There is an factory installed tranny cooler but it is pretty much obstructed by the SC. Thinking I need a tranny cooler with a fan but where the heck can I put it? I checked with ORW as they make a tranny cooler to fit with the Ripp SC but they tell me it will not fit the 3.6L Penstar. Any advice would be appreciated.

I am running a Ripp on my 3.6L auto as well, and my kit came with a new trans cooler to replace the stock one to make room for the intercooler. I mounted the new trans cooler below the intercooler. Did yours not come with one? The trans cooler listed on Ripp's site says its for an '07-'14 with or without a supercharger.

X2; your kit should of come with a trans cooler. As a matter of fact, I dont think the SC intercooler will mount w/o the RIPP provided trans cooler.

you could use something like this:
Dual-Pass Heat Sink Cooler, 18" | PSCMotorsports.com performance steering components, power steering

Thanks for the reply. There is a trans cooler behind the SC but it is almost completely covered by the SC. Had the SC installed by 4 wheel parts so not sure if it is the factory installed cooler or one that came with the kit. I'll check with the installer but with so much of the cooler covered, I doubt much air gets to it...especially when going up steep hills slowly.
Also talked with Ripp tech...Ross who said the trans cooler should have been changed from the factory model to the one that came in the kit. Suggested removing splash guard from bumper if factory bumper or drilling holes in it but mine is a Warn bumper with low profile winch. He also suggested that for heavy duty towing many chose to mount an electric fan driven model behind the radiator instead of the Ripp model that goes between the SC and the radiator.

You may need a heat exchanger when towing. Some Racers use them. How you would fit it is another challenge. Water cools better than air. For example if you burn your hand do you wave it in the air or do you put it into water?

Are you running stock tire size?

Don't know how much room there is on the 3.6, but this where I put mine on the 3.8. I don't tow anything, but have never had "Hot Oil" with this set-up

What tranny cooler is that? I have a Ripp and my transmission gets hot when climbing the hill to Big Bear.

Running 33s so not too massive. I think the issue is more the towing stress going up hills.

Apparently not enough room behind the radiator. Am trying a larger Hayden cooler in front of the radiator but I have concerns about engine temps by having too much space taken up by the trans cooler in front of the radiator. Will see how it goes. Will take photos when installed.

In my 2007 I have same issue going to Big Bear, but only on a big hill like that, I can drive up the 15 N with no issue, middle of summer. So it is something about the hill and it's quick incline, But I have 40" tires / d60's and cant expect the little cooler to manage this. But on the other hand when it goes up that hill that RIPP makes my big JK move faster than many of the standard cars going up the hill, passing is no issue. If the hot oil light goes on, I stop for a few minutes it cools down and go again usually only have to stop once. In Moab when I told Ross about it he said of course, and gave me an altitude pulley I will put this on to try it out.

Griffin and CBR sell heat ex changers that hook to radiator fluid, for towing 3,000 pounds you might have to get one. There are also heavy duty transmissions built for towing so you may need to upgrade, I think RIPP sells them now. IMHO the desire to tow 3,000 pounds will cost you more money than you have already spent, it is not your RIPP, it is the transmission, it was not built to support the added HP and towing.

It's one of the two that come with the PSC hydro kit that used to sit side by each in front of the rad before the SC install. I shit canned the other and use a derale heat sink style for the steering now.
