2012 JK manual trans in 2012 Auto Jk?

Is it possible to take a manual trans from and 2010 jk and put it into a 2012 auto jk. I have a auto 2012 JK but I'd much rather have a manual trans for a little bit better fuel and more fun driving down the road. I don't do any crazy off roading mostly just drive on trails. I found a donor 2010 jk that the owner is parting out. It looks like most of the jeep is still there mainly just body panels are missing.

I don't know how involved the swap would be.

That said, you're not going to gain much, if any in fuel economy, especially if you are "having fun" driving down the road.

Also, the manual in the JK is a pretty sloppy transmission. I have one, and I love it, but it's the sloppiest shifting manual transmission I've ever driven, aside from my dad's old 78 Chevy truck that was 3 on the tree. We routinely had to stop on the shoulder and take a screw driver to dislodge the jammed up shifter mechanism that went from the column to the transmission.

The manual transmission in JK's from 07 to the present is the same. However, going from an auto to a manual is somewhat involved. The "new" auto starting with the 12 JK is a good trans. IMO, you're better off leaving it alone. Or, find a manual trans. JK and sell the auto. if you prefer a manual. Plus, you really won't get better gas mileage.

I agree that you will not get better gas mileage unless you are much more disciplined that I am. I love driving my manual. Too much fun for fuel economy but I am OK with it.

It's not just the transmission. It's the TIPM and the shifter and the console. There may be some additional wiring changes in the dash.
