Previously I discussed ongoing issues with my 47re, including no communication, no overdrive, no tcc lockup...

I had already condemned the pcm and bought a junkyard pcm to replace it with. It has the same issues, could I have a bad pcm from the junkyard or is it more likely i have a wiring problem that either stopping communication or frying the pcm? What wires should i check before sending my pcm to be rebuilt?
