Bangster,the 6F35 doesn't have an external TCM, it is all in the transmission. Here are the 2 connectors:
All the TFT, OSS, TRS, SSx etc signals to/from the PCM are from that C1520A connector, C1520B is the TSS.
Bangster,Besides the TRS signal, sounds like one of the shift solenoid wires is not hooked up. Do you get any codes at all, like for the TRS or for the solenoids, OSS, ISS, TSS?
Right on the other side of that pan the connector connects to is the shift solenoid frame with other sensors connected to it
Personally I think it sounds like a ground issue, I don't think the TRS (why it won't start thinking it isn't in park/neutral) or shift solenoids share much.
I think that is for a DCT transmission in a Focus or Fiesta, right?AE8Z-7Z369-F (TCM OEM part#) can only be obtained if you find a dealer with one in stock willing to sell it. I currently have one covered under warranty that we can't get. Ford parts distribution has told us there is no ETA.
