I just got my Dynatrac front axle with 4.88's and ARB and my rear 44 with 4.88's and ARB installed, along with new JE REEL drive shafts. Now that it is all put together, my transmission stays in second gear(automatic) and wont shift out. It even starts off in second gear. And when shifting from drive to reverse it takes awhile to shift. It is throwing a P0371 code and yes I have looked the code up and possible things that could be wrong. It has transmission fluid as well. This is a 2012 JKU, so if anyone has any thoughts on how to fix this, please speak up. Thanks.
