Matt416 Posted April 11, 2023 Share Posted April 11, 2023 Last summer, the torque converter clutch on my 2010 Transit Connect started acting erratic -- suddenly disengaging, or not engaging when it was supposed to. Sometimes the shifting was very harsh. I plugged in a laptop with Forscan, and drove around recording the odd behavior, and got error codes P0741 and P1744. I went through all the diagnostics in the shop manual (checked the oil, checked the wiring, etc), and the problem seemed to be in the PCM. The problem is sporadic -- for several months I didn't have any problems, then the torque converter clutch started acting up again, with the very harsh shifting. I ordered a new PCM from FlagshipOne, and made it very clear to them that I do not have PATS, no chipped keys. They said it would be 'plug and play'. I installed it, and my Transit would not start (would not even turn over). I used Forscan, and got an error code B2139 -- "the PCM identification was not recognized by the PATS module". In the workshop manual, it says that if a PCM is replaced, "the parameters MUST be reset in both modules, or the vehicle experiences a PATS no-start. This occurs even if the vehicle is not equipped with PATS." Now FlagshipOne is telling me that the PCM they sent is not 'plug and play', and that in my situation the unit has to be programmed by a mechanic or locksmith. I am not that familiar with Forscan, but is this something that I can do myself with Forscan? If not, how do I find a mechanic or locksmith who knows what they are doing? I don't want to mess up the programming so that even my old PCM doesn't work. Quote Link to comment Share on other sites More sharing options...
Don Ridley Posted April 11, 2023 Share Posted April 11, 2023 (edited) Post this question in the Forscan forum. There may be a service procedure in Forscan that will do this. I don't understand all the PATS details. Here is info on programming PATS with Forscan. https://forscan.org/forum/viewtopic.php?f=6&t=839 PATS programming is supported by Forscan for your model year. Vehicles newer than 2012 or 2013 are not. Edited April 11, 2023 by Don Ridley Quote Link to comment Share on other sites More sharing options...
Matt416 Posted April 12, 2023 Author Share Posted April 12, 2023 Hi Don, Thanks for the advice. I joined the Forscan forum and posted my question. The link you posted (and most of my searches) explain how to reprogram PATS or make duplicate keys. My Transit doesn't have PATS, and I am trying to reprogram/reset the PCM and instrument cluster module so they will talk to each other. Hopefully someone in the Forscan group will be able to help.

Matt416 Posted April 17, 2023 Author Share Posted April 17, 2023 Hi Don, It seems I have (had) an unusual situation, and someone on the Forscan forum suggested I ask Forscan tech support directly. Tech support was great! They responded quickly, and gave me what I needed to initialize the instrument cluster so the PCM recognized it. I bought the Forscan extended license to do it -- a whopping $12! -- that saved me from being at the mercy of a locksmith or Ford dealer. Unfortunately, the new PCM did not solve my torque converter clutch/shifting issues, but at least I have narrowed it down to the transmission itself (probably the solenoids or internal wiring harness). I'll post a more specific question about that. Quote Link to comment Share on other sites More sharing options...
Don Ridley Posted April 17, 2023 Share Posted April 17, 2023 Thanks for the update. I saw your Forscan forum posts and you have been diligent in tackling this complicated problem. Quote Link to comment Share on other sites More sharing options...
