2016 jeep jk,.3.5 inch lift,35s..auto trans..
Just re geared to 5.13 and added a Detroit locker in the rear.Now im getting codes for p0733,cel will come on and trans will shift strange.Ive already re calibrated the new gears into the ecm. Im reading mixed reviews on comparability with 2012 and up with auto trans and having a det locker.Is there anyone out there running this set up currently?

Have you also put the new tire size in the ecm?

While you are waiting for other responses...
Are you getting any other codes? (Checked with an external code reader.)

I put the new tire size in as well,no other codes in either module.

Bad news. You can't install a Detroit on a 2012+ JK automatic. No workaround.

You can not, in any way, ever, run a Detroit locker or any other auto locker in the 2012 and newer JK.

This is old hat, been hashed over 1,000 times, and any half assed Jeep shop knows this. Time to get the tools back out and remove that thing.

As you google around, the situation repeats. I'll assume you never posted your plans on a forum asking advice, nor did you Google around for info on a Detroit in a newer JK? If you had done one or the other, you would have tripped on this well known factoid.

Oh crud...I guess my jeep shop didn't get the memo.Man i wish I would of seen this before hand..Do we know how a detroit E locker will work in replacement.If that will have any issues throwing codes in 2wd or 4wd. And thanks for all the reply's so quickly..

The Eaton E-Locker is good to go.
Any user selectable locker is good to go, air or electric.
Any limited slip (Detroit TruTrac) is good to go.

Hopefully you can get this resolved quickly and damage free, best of luck!

So the place I had all the work done said to turn off esc with a programmer and that will fix my issue of limp mode and cel .Any thoughts before I try this.
