I have a 2007 JKU with a manual transmission. I have a U0101 code that is titled failure to communicate with TCM. I'm really at a loss for diagnosing the issue. I believe my year model of TCM is integrated into the PCM. If im wrong please correct me. I don't see anything obvious and I don't have any other codes I would expect to be associated. Does anyone have a resource to guide me in the right direction? Thank you in advance
