That is what I am afraid might be the case, but also there are fiesta with new TCMs that have hardware number and with AE. Ford/dealer part numbers themself appear to be different between models. Transmission was serviced recently with a full clutch, forks, and seals replacement. From time-to-time clutch actuated by motor A will report as stuck. Swapping actuators does not move the issue to clutch B. Every time this issue happens, resetting TCM by power cycling it or the battery will make it shuffle gears and it will work great from there. Adaptations done on "original" TCM as well.

Exact reason is unknown, we suspect it is because of different networks and wiring in Fiesta and Focus (that are different platforms in fact). There should be 2 ways to program it:

1. In recovery mode with power off/on, to "catch" the programming session before the main strategy is loaded.
2. Program the TCM on the table.
Ahh, that makes sense, that is probably where my misunderstanding that newer unprogrammed TCMs can be programmed to focus or fiesta, because they are blank. I misunderstood it and thought that used modules could be re-programmed for a different model.

I will try recovery mode in the car first, and then directly to TCM if that fails.

Besides things noted in post below, are there any other recommendations or notes to keep in mind during recovery?

Thank you for your input and prompt response
Hey there, did a new TCM solve this issue? And when you were getting codes, was clutch A stuck ON or stuck OFF? I'm asking because I think I might have this exact same problem. Clutch A sometimes gets stuck ON (code P07A3) but it's not common, and resetting the TCM always makes the problem go away for a while. Haven't replaced the forks, bearings, or clutch yet. The fork seems to move fine and retract by itself when I remove motor A and turn the socket by hand. I ordered a new TCM, although it will take forever to arrive because they're on backorder. The car used to randomly slip into neutral while driving, although cleaning the ground points seems to have fixed that. Only have the problems with clutch A getting stuck now. Just curious to know if a new TCM actually fixed your issue. I really don't want to remove the transmission to inspect the clutch components, but I might have to if this doesn't fix it.

Replacement TCM did resolve the issue with transmission. I no longer recall for which clutch stuck on the error was for, but I do remember that when it happened the car would stick to even (2,4,6) gears only. Resetting the TCM and adaptrations did always show touch points to be high 10-12mm which aligned with previous owner saying that clutches were replaced. At the time I was still suspecting that forks may not have been replaced as part of the clutch replacement, and therefore replacement TCM would have been a waste. Luckly for me clutches were replaced and so were the forks.

With replacement TCM (Focus) re-programmed for Fiesta car now shifts as normal DCT.

Excellent, thanks for the information. This gives me hope that a new TCM may solve the issue. Mine does the same thing, it reports clutch A as being stuck and only uses gears 2, 4, and 6 (and R of course). For now the car is still drivable so long as I reset it occasionally, so I'm just hoping it'll last until the new TCM arrives.

I just successfully re-programmed 2 TCM units from the Ford Focus, and into my 2010 Ford Fiesta S. Initial unit was worrying, as I've done the disconnect/connect negative battery terminal multiple times. I've tried about 5 full programming attempts (all interrupted at 30% mark). On my next attempt, instead of placing the terminal ring into the battery post, I then just tried to rest it on top of the post, and suddenly it went into recovery mode, and proceeded to update the firmware. On my second TCM unit, I got it during the first programming attempt, but maybe on the third disconnect/connect to the battery terminal. I can confirm that this process works.

I used FORScan 2.4.7, with the Vgate vLinker FS OBD2 USB Adapter I picked up from Amazon.

Fiesta TCMs sell for about US$1000 here in the Philippines. Highway robbery. I got 2 used Focus TCMs from eBay (average of US$200 each), and successfully reprogrammed those. I initially brought the Focus TCM to a local "Ford Expert", and they were unable to reprogram. Luckily, I came across this thread, and had a successful DIY. I now have a spare pre-programmed TCM I can easily swap out, in case of another failure.

Many thanks @PancakeFord for the detailed instructions, and reply to my personal message. I really appreciate you. Thank you.

Awesome that this also worked out for you.

Per dev's post above they may have improved the recovery programming process so triggering ignition with batterie's negative terminal may not be event needed. And from logical point of view on this process, disconnecting and re-connecting batterie's negative terminal powers TCM off and on completely thus making conditions to get into recovery more likely.

Without that, turning ignition off with a key and waiting for a longer time for TCM to power off completely should also work.

How can you tell from firmware read pg for TCM what is a Fista and or a focus? From what has happened to me with my focus I’m being told I have different gear ratios rather than different firmware?

FORScan wrote: Sun Jun 04, 2023 3:48 pm Thank you for the feedback, it is important information. However, I'afraid I haven't understood the principal difference between the way 1(that didn't work) and the way 2 (that worked). In both cases you powered off/on the TCM by disconnecting and reconnecting the battery negative terminal. What is the principal difference between these ways? I'm asking because we'd like to improve the recovery mode.
In first method I disconnected battery negative terminal when FORScan prompted ignition off. Then when prompted to power on module (in recovery), I connected the negative terminal of the battery once.

In second method, I connected and disconnected negative terminal 2-3 times within 1-2 seconds until noticed that log showed something SBL upload (or something along those lines). During these connects disconnects transmission attempted to do the shifting back and forth as it usually does when battery is reconnected.

Maybe the second method was just a coincidence, but I did try first method at least 15 times with no luck. The second method worked during first attempt. From BMW ECU programming I remember that doing this puts ECU into forced bootloader/recovery mode when it expects only a firmware and nothing else.


Currently using FORScan 2.4.8beta and I am having the exact same issue installing a 2012 Focus TCM on my 2013 Fiesta. I would love to attempt this recovery reset but the vehicle is not equipped with a physical key. My Fiesta has a push button start and no physical key. Would you suggest an alternative to leaving the key turned to the on position while cycling battery power? I may try holding my push button while someone else taps the battery terminal on/off.
You had mentioned bench testing it into recovery, is that something you can do without a fancy setup/custom harness?

EDIT: SUCCESS. After a few attempts of turning off and on the car, what seemed to work is to turn the ignition on with the push button and once the FACTORY reprogram under RECOVERY mode was started, I was able to quickly remove and tap the negative battery terminal. It succesfully downloaded the factory "tune". I then installed the updated tune, then the clutches would actually adjust themselves and it drives perfect. Thank you to all that contributed to this.

Just done this with my b max , I put fordscan on and downloaded the original tcm part numbers and configuration , removed the laptop from vehicle fitted the used tcm. I believe it was from a focus, and then I opened up my laptop and open up the fordscan , in my living room , nowhere near the car ,( it has to be the beta version, the latest version would not work) and went to tcm recovery mode , it prompted to switch ignition off , then asked to switch ignition on. At this stage I went to vehicle , plugged the laptop in pressed ok on the laptop and waited 10 seconds before I switched ignition on , about 3% it reached before I switched the ignition on. And it programmed successfully , then I programmed the clutches ,

WOULD LIKE TO SAY THANK YOU , TO THE ORIGINAL PERSON THAT POSTED THEIR FINDINGS , YOU SAVED ME A TRIP TO FORD. AND LOTS OF MONEY

Hello, I'm brand new here in the forum. I've been reading a bit.
my car: Ford Fiesta 1.6ti / 2012/85500KM
my problem:
-Reverse gear doesn't work sporadically,
-Gears jam when changing,
-Error message "Clutch B" blocked

I have Forscan 2.4.12 and VLink FS adapter

What I've already done:
Changed clutch sensors A&B, reconnected the ground cable and connected it better, I'm going to change the gearbox oil.
I want to eliminate as many sources of interference as possible.

I've ordered a used TCM (on the way).
To my question:
Can someone please describe to me exactly how I have to go about programming the new TCM?
Which programs in Forscan do I have to run and when? What should I do if the data is not overwritten correctly (which pole (minus or plus) should I remove to perform the reset if there are problems?

Thanks for your info!
