I looked into it and even added the necessary wire. It needs the VSS signal coming from the tcase and not the transmission in order for it to work. Since all these swaps utilize the VSS from the transmission that signal wire will trip up the TCM.Anyone tried grounding Pin 16? According to Grok, this can change the behavior of the transmission slowing the output shaft (a still spinning output shaft being the likely cause of the grinding between hi/lo).
