I'd been having Transmission shift problems. Specifically, 3 to 4... just didn't shift. It was throwing a P1603 code... failing PCM. This isn't good, since they aren't manufactured by Jeep any longer. However, Wranglerfix.com (in Florida) builds NEW - Not Refurbished - PCMs. I posted a Video on my experience.

Mark (@Wranglerfix) is not building new PCMs to my knowledge, he is just repurposing used ones and updating / fixing them. I have one of his PCMs and while it works great, it’s definitely not new.
Mark, correct me if I am wrong, but if you are actually building new PCMs that would be something that is definitely worthy of a big announcement.

I do not build new pcms. I have made that abundantly clear from the beginning. We figured out which oem part most mimics the 05-06 TJ and made it a plug and drive unit.
