Hey I have a 2014 Jeep Wrangler Sport with the trouble code U0414. Does anyone know what would cause this? I found others saying they needed to replace the TCM. How hard is it to replace the TCM? Does the new one need to be reprogrammed by a dealer computer?
Alarms are going off in my head-
A jeep, wrangler, and a U code - WHAT did you do? Is vehicle STOCK? Any other codes, issues?
Which eng trans? maybe a 3.6 and a nag1 trans? I will check for TSB's if I know that info
