I just recently finished a super duty axle swap in my 2012 jk and have been fighting gear ratio error faults in the trans. p0731 fault keeps returning...I'm running the artec 60 tooth tone wheels in the rear and the 60 tooth in the front with 5.13 gears. I'v tried reprogramming ratio with an AEV procal and obd j scan. I've programmed ratio to 4.44 gears and have tried every ratio down to 3.21 and up to 5.38s with no luck. Even tried reflashing the tcm and doing several hard resets. Anyone have any ideas?
