3.21s in an auto?
Just wondering if it would be possible to run 3.21s in an auto.
The reason I ask is that I have 3.21s in my manual jk. My mother has an 07 auto jk unlimited with 4.10s and at some point may be trading it in soon. I was thinking of swapping our axle/diff assemblies before she trades it in. However, I am wondering if it would be drivable with the 3.21s

There is a reason the automatic doesn't come with 3.21 gears. It would run like crap.
I wouldn't do it without telling the potential buyer why it drives so badly, before the trade.
It wouldn't be right to put 3.21's in it and not say anything.
