I did a bit of web crawling to see if I could find the answer to your question (as I'm sure you did). At least one site I saw had a separate listing for the 07-11 from the 12-16 for a manual tranny. I would have thought that, if anything, there might be a difference with an auto as they went from the 4 speed to the 5 speed in 2012 but I didn't see any listing a different part for JKs with the auto. Most sites (as I expect you may have seen), have no separate listing between the two time frames. I'd call a driveshaft maker when they open on Monday.
