First off let me fill you in on the changes. 2013 wrangler JKU with 18,016 miles. Everything was fine on my regular 35's and3:73 setup with an AEV pro cal. I built a DV-8 housing, ARB locker, RCV 35 spline axles, Reid knuckles, temkin unit bearings , Revolution 4:88 gearing. Out back Yukon automatic locker, 4:88 Revolution gearing, new wheel sensors from local Napa.
Absolutely no problem before this change. Reprogram the jeep with AEV pro cal after a battery disconnect to be on the safe side. I can drive the jeep for about 20 miles and all is good, making a number of stops and turns. Then it appears to go in 2nd only and I loose capability to use bump shift. No CEL.. no code??? I can restart and it's fine for another 20. Any ideas?? Maybe the rear napa sensors or rear locker? I've seen several JK's out this way running the auto Yukons so this has kind of stumped me.
