The aftermarket like a Hayden or B&M that sits right there in front of your radiator should work just fine. I know a ton of JK guys that run one brand or another in that position.

Shoot, Mine is actually between my SC intercooler and the radiator and I have no trans heat problems.

I can't remember exactly what temp is but 165 to 175 comes to mind for mine. I have not had my Diablosport hooked up in quite a while to read the gauge...I should, just to check it.

On my '07 I used a Ford SD std cooler...worked great and was free except for the AN fittings.

170-180 , 200 pulling a large hill with camper in tow isn't bad at all. However, the cooler you can keep it, the longer the transmission and fluid will last.

I have done a few things to mine, and it stays in the 90F to 130F range under almost all conditions.

You do have an OEM cooler, btw. Pre-2012 JKs have a small one at the bottom of the A/C condenser. It's too small, and is blocked by the bumper. 2012+ JKs have a larger cooler mounted in the direct airflow through the grill. It's more like an aftermarket cooler.

Mine runs 130 - 145, I don't tow anything. But that is normal temps just running around town. Rock crawling or climbing hills it gets around 180 - 195.

OK. I see what you meant about not having an OEM cooler.

Go to this thread to see what I have done to cool all the stuff under the hood; engine, transmission, electronics, intake air, etc..

Transmission Over Temperature Code P0218

I just started getting a transmission code coming on P0218 stating that the Transmission Over Temperature Condition...which I have never received before.

My jeep has a 6in Longarm kit on and I am running 40in Tires. Never had this issue as I have had my 40's on since Sept of 2014...I recently drove the jeep, honestly 5 miles after it sitting for 4 hrs, and the engine light came on. Curious what would be causing it as its not under load.

AFE cold air intake, MBRP exhaust and aftermarket headers...but why is my transmission overheating...I dont get it.

I am looking into a Mishimoto Transmission Cooler right now as we speak...just want to get some ideas.

Let me know what you guys have experienced!!!

Thanks,

Nathan

Has anyone put a tranny cooler on the 2012-2015's? I was wondering about this. I'd rather have one and no over heating issues than have some.

after a few complaints to my jeep dealer about the trans. overheating, they added a cooler at no charge. they said that they new it was a problem, but didn't want to issue a recall.

I installed an ORW cooler on my 2010 solved all of my problems.
I just put an LS3 and 6l80 in my 10 model and don't need the cooler.
I would gladly part wit it for 200.00 plus shipping.

Mines a 2014 and I've just been watching the temp guage... just would like a little bit lower. I'm going to Moab next month so just being proactive.

As mentioned a few posts above, the 2012+ JKs already have an aftermarket-type cooler on them.

re: Stand alone tranny cooler and temp ?

I have a B&M for 8800lb GVW vehicals w/ the plates instead of fins on my `11 . It was one of the firs things i added and per the superchips diagnostics, my temps range from 135 to 185 depending upon what season & how long she`s been idling in the sun ( black JKU) or if this is mid-Winter night and she`s just started to get heated-up. Generally , my opinion is `if it`s an automatic; cooler + aux and if need-be add a spahl puller .....`

this is one of my Jeeps of the two I have & five I`ve owned. My other present Jeep is an XJ that is at 380k original miles & will see 500k. Just to show I am kinda into Jeeps I will attest to heat being the one true killer of everything if you let it be. hope you get my drift & it helps

don't have any answers here but I saw some nice Jeep logoed gauges recently on the autmometer web site. Here's the trans temp gauge in case it is of interest.
