PM returned. I'll send tracking once I have itBB just got back to me and said the PCM is commanding shifts like it’s supposed to do it looks like it must be the harness. So I’m waiting on Performabuilt to get back to me so I know for sure I’m ordering the right part. I’ll replace the manifold pressure switch too and if there’s anything else like the TCC solenoid I’ll do that while I’m in there. I sent a PM to you @pwtr02ss to borrow that harness tool. Hope it’s not the external harness, I guess I’ll see if the internal one fixes it.
