The transmission learns based on your driving habits in the first 1K miles or so. If you push it through a bunch of different scenario's (D, S, S+} and change it up often, it should be pretty good. Other Focus owners can attest to how my transmission acts superb.

Edited for kindergarten grammar. Stupid phone.

This ^^
This 12B37 is my second reflash of the tranny software. The first time I had the software re-installed, I drove my car in a ''conservative'' way when it was given back to me. I didnt see any real difference in the behavior of the tranny and to be honest, at that time, I still found it to be a bit jerky and unresponsive. However, after doing 12b37, I followed some of the suggestion left here and there in this forum and drove my car in a more ''sporty'' way once it was given back to me. I must admit, like I said before in many other posts, that my car now behave in a more responsive, fun and peppy way. The fuel economy is still there when I hit the highway and in city aswell, if I dont drive like an maniac :)

Can you explain how something that's been programmed to act different, can be reverted to something that doesn't exist anymore? It's like saying "I updated to MSOffice 2007, but after a while, it reverted to MSOffice 2003". Doesn't make sense for me. But maybe it's just me.
Google "adaptive learning"

As far as I know, there is no need to do the 'learning procedure' after the transmission had this FSA. The 'transmission learning' has nothing to do with the way you or me drive, but with its mechanical components. Because it does not shift different because of the styles of driving. At least this is what I understand by "DCT learning" process. I don't know about a car who's so capable to learn to shift gears only from how hard or how light a driver presses the acceleration pedal. And usually, after a Full reset of the DCT, this one has to learn again its components, this is why it is a bit "harsh" at the begining and then become "smoother" in time and the number of miles. Not the other way arround, as you suggest. But hey, I might be wrong.

Are you sure about that?

Although it does seem to be at the cost of high speed shifting. I've noticed that if I have to get on the gas for highway merging or if I have to make a quick maneuver, the transmission isn't as responsive or smooth. It's almost like it takes longer for the tranny to make up its mind what it wants to do. I've driven stick shifts for the last 20+ years. What I'd like to see is a chart of the gear / RPM shift points before and after the software update. I'm used to getting RPM shift point recommendations in the owners manual on a new vehicle when I get a manual tranny, so this info has got to be out there somewhere.

Who knows, maybe it's just me.
FrostedG -

So, has 12B37 been successful for you? The RPM shift points with this Customer Satisfaction Program is a good idea. If you haven't talked to your dealer about it, please post it here for others to share too: http://Social.Ford.com/.

Hopefully things will improve for you. It's frustrating having to deal with bad shift points.
Rememo -

Correct; it addresses transmission shift quality issues in general. Your dealer idea is scary, to say the least!

Apologies if I haven't introduced myself. I'll be taking over as the new Ford rep on these boards. It's nice to type to you! By the way, I love doing it old school too!

I'm happy. Based on some jerks on this board, I thought the shuttering, noise and vibrations from the transmission were because I "didn't know how to drive" - - amazing what they can fix that now with a TSB update, isn't it? [/vindicated]

I'm glad this program has been a success for you! How often do you use "S" mode, if you have it?

These type of expectations are always natural. We're trying to make the gear changes seamless as possible. Your transmission advice is great!

I also swear to god that outside air temperature affects shifting, as it seems to get worse the hotter it is outside.

I'd like to send details to your Customer Service Manager for review. Please send me a message including your VIN, mileage, phone #, and servicing dealer.

This isn't normal for any update. We intend it to work correctly for the life of the car. Your last sentence made me chuckle.

To all members, please reach me by PM if your Focus is still experiencing harsh shifts after 12B37 has been completed.

Kind regards,

Thomas

You are correct on the 1k miles. My dealership reset my car after the update, though it isn't required (had other issues). I would think that the learning process does have something to do with how it's driven just based on other members' feedback.
My assumption is that it learns on trial and error, but I don't know 100%. My car didn't shift 'hard', just kinda retarded. I don't mean to imply otherwise.
I just re-read my previous post, I sound like a moron. Thanks, Swype. Stupid phone.

So, if it runs worse than at the begining, it is because of the driving style the driver uses. And this is something really bad if the DCT acts like this, if you want my opinion. Because it implies that two persons who drive the same car, one Agressive and one Relaxed, will never be happy with it. I don't think Ford is THAT out of touch with the reality.
But again, as far as I know, there is no need to do an adaptive learning after this FAS. And this point I was discussing about.

P.S. Does the DCT have ATC?

Pretty well all automatics now are adaptive, but most are not the kind that learn the drivers habits. That Ford article stated: "Available on many North American vehicles", but not neccessarily the Focus. They would probably use it in advertising if it did that.

A TSB on the Focus stated "NOTE: PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY". It doesn't say anything about the user driving habits, and all the tech literature on the DCT I've read suggests it doesn't apply to driving habits.

Since driving habits vary from user to user, that may be more likely for high end models like Licolns which have user stored profiles as a standard feature.
