Car has been sitting because it was in having intermittent stuttering. i remember seeing PCM codes although i cannot remember them. Fast forward about two years later i start working on it. starts and drives okay. every other drive it wont shift into overdrive and running rough. changed ATF4. car wont shift out of second now. changed input/output sensors, and crank and cam. car runs better but still stuck in second and no speedometer. scan gives u0101, p1603,p1604, and 0037, 0031. i began thoroughly inspecting harness and connectors. however looking at C1 PCM connector i am not sure if pin 13 is supposed to have a female copper to marry up with pin. i see it as vehicle speed signal on schematics but i cannot find anything to verify if there needs to be a copper piece there. i also didn't make it to the scrapyard before it closed to check on a different one. picture I will send. thanks
