Howdy,
I tow a 1500 trailer I have an 2008 unlimited with 33's, auto, 5.38's.... I have been worried about having a fire so this is what I have done to reduce my fear... Jeep just release the auxiliary trans cooler for the 07-11 jeeps same as the one used on the 12's, got it installed this weekend... Also I have the super hips flashpaq with transmission shift point tunes... Very cool keeps the tranny in gears longer especially when climbing the mountains on our way to Colorado... Last but it lease, did some research on the civilian jeeps being sold in Egypt, they have a dual fan setup, our same electric fan and a mechanical fan in addition too, so I just order the parts from jeep to make the addition of a mechanical fan if this doesn't solve the heat issue then I guess I'm just going back to hiking the mountains.... There's a couple threads on adding a mechanical fan out there... Parts I ordered from jeep, Fan blade clutch and shroud all bolt on parts!
Have cool thoughts!

search this forum you will see the Egypt jeep setup in pictures and you will get all the dialogue it gets real touch with the parts. Because jeep has codes that are hard to define... Go online and search mopar parts overstock here are the parts I ordered Cooling fan. Mechanical. 52079654AE $63.28
1 SHROUD. Fan. 68039594AA, 58.00 can't guarantee they will fit but hell it's a jeep.... Empty every pocket and do it twice to make sure!

Can't wait to see how this works for you.
edit:
The fan and shroud seem to be in several dealers' inventories, and through the online MOPAR parts stores.
The shroud in the post above seems to be for the manual transmission.
This part number is for the automatic transmission:
Fan Shroud, Automatic Transmission
2007-2011 Jeep Wrangler JK
Part # 55057123AB

Yeah I was concerned about other sites listing as for manual but on the mopar overstock 68039594AA is the listing for "all jeeps with air conditioning" so I went with this one ... That's why I thought the listings were screwy if you didn't know all the codes... I have ac which I think most us jk's do... I could be wrong

I was thinking the same thing. Here is some info I copied off AEV's website regaurding the hood
JK Heat Reduction Hood FAQ
Does the Heat Reduction Hood really reduce temperatures?
Absolutely! Of course we designed the hood to be aesthetically pleasing, but we also put a lot of fluid analysis into the location of the vents. There is a low-pressure area created at the front edge of the hood when the vehicle is in motion, and we placed the central vent of the hood in a position to take advantage of this. Since air likes to move from high pressure to low pressure areas, the placement of the center vent causes cooler outside air to be sucked through the radiator and up through the hood to fill in the low-pressure area.
Chrysler has tested our hood in both the wind tunnel and on one of their most severe hot weather tests, the Davis Dam Grade outside of Laughlin NV. This is about a 15-mile grade with very high engine RPMs, high ambient temperatures, and high loads. Here are some excerpts from Chrysler’s “hot trip” report: “3.8L engine coolant temps ran approximately 5 degrees less with the AEV Hood. AEV hood was then put on a diesel (2.8L) JK and very positive results were experienced. The vehicle ran 5 – 7 mph faster up the grade with a trailer.”
When Chrysler subjected the hood to a different test in the wind tunnel, the results were similar “DAVIS and USCTY were run to evaluate AEV hood. AEV hood helped coolant temp (2.5 degF), Trans temp (4 degF) and Air box inlet Air temp (8 degF). It also helped some thermal protection components during Davis55.”
Besides engine performance, the AEV Hood can help significantly with the heat buildup in the under hood electronics, such as the TIPM (Total Integrated Power Module) which will shut the entire vehicle down if it gets too hot. Don’t be fooled by other hoods that are designed solely for aesthetics, they won’t help cool your vehicle (many have the vents placed in useless areas from a thermal dynamics perspective).
