while the auto trans in the 07-11,then the 12s thru 18 3.6litre jk/JKUs all come from Dayton with one ' built-in' to the factory cooling system , once the OEM GVW exceeds 6000lbs ( armor, heavy tires& wheels,redonkulous heavy steel bumpers & winches then the subsequent cage or added goodies ...suddenly an automatic transmission designed to propel 4 adults in a 4 door Wrangler comfortably across 'murica ( Trail Tested !) ...once you add the weight of 3-4 humans to it in add-ons , well, after that adding anyone but a driver is going to be a regular effort ....add cargo & a slurpie & suddenly that tranny is working on those incline grades about 4-8 times as hard as it was designed to.
you need an aux tranny cooler that's gonna further cool the return tranny fluid lower plus can be more exposed than the lower quarter of the factory one you're using & that the top bit of that Warn is in front of slightly.
Not to mention , were I running heavier steel stuff like you , I'd have a much greater CFM fan doin my cooling , but that's just opinion.
If you have aux cooler , I missed you saying so .
the Jeep is a heavy pig. You beefed yours up. You like putting on a metal cage & four layers of heavy clothes then running to work with a bandana over your mouth & nose in June?
Well, you're sorta doin that to your Jeep from looks of it. Aux cooler. Hood Louvers placed correctly or get positive airflow versus the deadspace lack of flow your bumper maybe generating under hood.
the Gobi & kc bar add lots of weight. You gotta plan for Jeep breathing before bolting this stuff on .
