I ended up taking my money else where and ordered exactly what I wanted.
To the OP-Take your time and get what you want..even if it means ordering it and waiting. It really isnt that bad of a wait anyway...at least it wasnt for me @ 4 weeks from order to delivery date. I too had a tough time deciding on auto vs manual...all my other toys are standard but for offroading I just wanted an auto. Plus it'll be easier for my lady to drive should the need ever arise. Anyway...GL to you on your quest.

I had a 2008 and a 2011 JKU - both manual. the 2008 had 3.73 gearing and the 2011 had 3.21 and boy was it evident when I upgraded to 33's. The 2008 was happy as can be but the 2011 was so sluggish it made me hate my life (both had 33's).
I know this time around I want something with more power, which is why I'm going with a Rubicon... I'm only able to find *1* single rubicon in my area that is 4dr - and it's auto. I test drove a 2012 JKU 6 speed with 3.73 and that 2012 JKU Rubicon with 4.10 auto and man... I have to say the 6spd with 3.73 just had me grinning ear to ear. The 4dr auto felt very 'sloppy' to me... that's the best way I can put it. Not in regards to transmission, but in regards to the general feel of driving the vehicle. I felt very much more in control with the manual... but I'm not entirely sure something wasn't wrong with that 4dr auto... I mean, it's the only one around here (within 100 miles or so) that is still on the lot.
The reason I'm so on the fence is both my 2008 and 2011 sticks jumped all over the place when I hit a bump - and it always freaked me out. My 2008 had a light noise coming from the gearbox (same noise my buddy's 2009 JKU Rubi has as well) so I'm just wondering if the 2012 will eventually have the same thing...
Either way, it's gonna be hella fun to drive.

Shifting through the gears in the manual is FUN, but a LOT of work and on a daily basis, in traffic, and when trying to get around in mixed city/highway its just too much work for me. I had a 2009 6-speed and i liked it, but my auto 2012 is amazing and i do not miss it at all. However, i still do have a manual 6-speed mini cooper, but way easier to shift and its a toy/fun vehicle as well as urban commuter.
The automatic on this 2012 version is amazingly smooth, holds gears, is manually shiftable, and after testing a 6-speed driving up to 11,500 feet in Colorado with both, i can say that they both are fine, but the manual is a lot of work to drive and maintain speed with traffic going uphill at 70-80. It just requires lots of thought, involvement, and work. The auto over a longer time period will be better for me. If it was just a local toy and only offroading where i was not driving it to and from work, i would maybe choose the 6-speed. The way the manual is geared, you have to really wind it out and it vibrates a lot more than the auto but as most would agree, more fun to drive. On those cold days when you want to press the auto-start in winter, get in, talk on the phone, drink your coffee, change the stereo, the auto is sure nice. On a hot summer day with the top off, country backroads, the 6-speed rocks and would be better. Dang, can' have both, but at least the auto allows manual shifting for high altitude driving. Hope this helps. Enjoy whatever you get. They are both excellent. BUT, do not get either if you are not sure, its really expensive to change your mind. LOL. Enjoy the jeep!!!

Why in the world is San Antonio, TX out of 2012 4dr JKU Rubicons!? Blows my mind. I've been watching like a hawk since just before xmas... and none have shown up.

Hey guys just wanted to share this with you.. The 2012 comes with an Evan skid stock 
I was just under there seeing if it was the same dimensions for ordering purposes and then I was like oooh looks like I need a new first mod.

The 3.6 has ZERO problems. I haven't noticed ANY performance loss whatsoever. If you get 3.73's then you will be even happier.
I saw the chart before I upgraded tires and it scared me, but I know now that I will not have to spend any money regearing.
Only thing that I have to do is recalibrate the shift points.... As they actually seem too high! LoL ... Go figure...
I wheel about 2-3 times a month.
However there are NO rocks here in middle ga.... So that might be an issue someone else needs to think about.
Wish I could let everyone test drive my set up and see for themselves.
It honestly feels to good to be true to me as well but it's great with 3.21's....
NO downshifting on the steepest hills while highway driving. There is no on/off switch for OD on the 12's anyway.
If I could go back and do it all over... I would definately get the 3.73-4.10 ratios..... But it's not necessary with the new motor and the auto.

The chart I created tries it's best to grasp the different terrain people roll over and sorting out appropriate gear sets. They don't fit everyones style and what they deem to be an acceptable level of performance. With the 2012s the penalty of kick downs is a lot less intrusive, and even unlocking the converter unleashes more power than the 3.8L. The Pentastar has far better efficiency as does the WA580 transmission. What you can get away with is a great deal broader than what it was before and stock gear sets keep open a lot more options for plus size tires.
With your situation, you are relatively close to sea level and some rolling hills to contend with. It's not the same as what people need to contend with in more mountainous regions, and at higher elevations. What works in your locale is not the same as what would work in regions with a greater variety of changing elevations. Speed also has a lot to do with things, as rolling over rural highways at 50mph is quite different than rolling over interstates at 70mph with 3+ degree grades. Perhaps most telling is the statement to do over again you would choose 3.73s or 4.10s which is right in the wheelhouse of what the charts suggest.
The charts posted are less than perfect as they don't have an appropriate measure for what one person or another feels is appropriate performance levels. They do their best to provide a fairly broad window of what will work and what are outside of generally accepted bounds. I can certainly change chart data based on others input but I need better data, supporting road conditions and more than anecdotal information. I'd like nothing more than having more reference points and more feedback to increase the accuracy of the charts although the window is still going to be pretty large as people have a lot of different expectations of performance levels and what gear sets bring to the table.
