I have another question. If I do the steps, on the first step, do I do it 10 times, or do I do it initally and then 10 more times?

Maybe instead of reconnecting the battery, following this protocol would be helpful even for cars that have been driven considerable distances since new or reflash. One could also position the car near a highway to perform the whole process seamlessly.

Noahsfocus, thanks again for posting.
Your right we will never know for sure because they usually don't give up this kind of information...

My assumption is that this is the final step of the adaptive learning reset procedure as described in the TSB (step2):

1.Reprogram the powertrain control module (PCM) and transmission control module (TCM) to the latest calibration using IDS release 75.02 and higher. This new calibration is not included in the VCM 2011.9 DVD. Calibration files may also be obtained at www.motorcraft.com.
2.Perform Transmission Adaptive Learning. Refer to Workshop Manual, Section 307-01 General Procedures.


So the Drive Cycle is done right after they do the PCM (power train control module) update. Performing the Transmission Adaptive Learning (step2) is necessary because the update wipes out or "resets" the memory in the computer (TCM, transmission control module). Therefore I believe this has to be the first step of the transmission learning process and needs to be performed right after the reset so the shift points are correctly learned and then the rest of the adaptive learning process can occur correctly during normal driving in the next few days.

Probably a reset is necessary for this Drive Cycle to be effective.

Not to say it couldn't hurt to do it anytime later but I believe it was meant to be done immediately after the update (or re-flash/reset). Probably the procedure itself doesn't "open up the system" or reset the adaptive learning.

Just to note if your actually following the instructions to do this that each time it says to "repeat" (10 times for example) that you would actually be doing it 11 times because the first time was already done on the previous step:

steps 1-5 will be done 11 times

steps 7-8 will be done 6 times

step 11 will be done 3 times

I will try to find the post someone made about "resetting the adaptive learning process manually by removing the battery for 10min" and make a direct quote from the original poster so more research can be done to see if this is true or not. I believe he said he used to do this to a mustang on a regular basis to help with sporty shifting or something. Anyway I will update here later if I do find it but if anyone knows already or wants to do more research or actually try the battery procedure then let us know what you find out.

No ...

at no time in this procedure do you go back to "park" ... probably wouldn't hurt anything if you had too but doesn't say shift back to park.

I really, really can't see how Ford ... can do something so dumb as what is being explained here to teach a transmission how to shift. What the hell is the computer supposed to be doing ... tuning everyone's car to a one driver customized product? Whatever happened to having a car do the same thing, the same way?

And we have to do this teaching cycle after we change the battery every 3 years ... or every time the battery gets disconnected for 15 min ... for some other reason ...

My car was built in April, and yes the trans has a few quirks, but now I am getting scared to update this ....

1st of all, thanks Noahsfocus for posting the drive cycle.

I'm new to this forum and been lurking around to see what issues existed with the 2012 Focus. Had I have known what I know now, I would have chosen a build date later than Aug. 12. BTW, my build date is Aug. 8. Lucky me, the steering TSB does not apply to my car but it feels like it needs it. All they did was a wheel alignment but it is not 100%.

To make a long story short, I had the DCT TSB done to the car 3 weeks ago but it still felt weird or erratic. I still had the shudder from time to time at stop and go traffic. It still shifted below 2500 RPM if I don't really press on the gas. This happens when it feels like it. I am not a happy camper.

This morning I read about this drive cycle that needed to be done after the software update. Well I had just came back from doing this and a half an hour of testing. So far I don't feel the shudder from a stop and shifting is now from 2500 rpm and up. In the highway I didn't really see much of a difference so I can't really make any comments about this.
Tomorrow will be the real test since there is always traffic jams on our highways here in Montreal.

It's not "dumb" it is basically going through all the gears a bit at a time so the computer can learn where to shift.

I have not heard or read anywhere that we'd have to do a drive cycle if the battery is removed. The computer has its own backup battery (usually li-ion) to maintain memory so it's not going to be forget everything by removing the battery.

The one thing I don't understand about mine is that at slow accelerations, by the time I hit 35 mph or 40 mph, in many cases, but not all, the car is already in 5th or 6th gear already. And I can sometimes feel it "rapidly" upshifting before I even hit 30 mph.

My old Focus (which obviously didn't have a DC system, but was the 4-speed Auto PowerShift tranny) was a bit better at shifting. It didn't get nearly as good as gas mileage as the 2012, but at least it was able to shift at semi appropriate times.

But then again, I haven't had the update done on my 2012 yet, so maybe this is one thing they will address. But overall, other than that, and the occassional lurch forward when I take my foot off the brake, the car's gotten much better (it use to be very hesitant for the first 2,000 miles or so--and sometimes I thought it was going to stall when accelerating from a dead stop).

As has been made clear this is a standard trans w/ computer controlled shifts.

It needs to learn the transmission and shift protocols. Imagine if you were shifting it, you would need to learn the trans. too. So we intuitively learn how and when to shift it. If you get in a different car and tried to shift the same way it would not function right until you adapted to it's peculiarities. If the computer came preprogramed for all trans, very few would work properly, so an adaptive software program is needed.

Get the update. Drive it for over a 1000mi. Then make your final judgement.

BTW, it is SUPPOSED to shift very rapidly if you're not dumping the pedal. That is how it saves gas. Mine does that too. If I push it a little, it will maintain the gear to well over 3000RPM before upshifting through all the gears. You need to maintain that acceleration demand though, if I back off, it will upshift sooner. You just need to learn how it functions and you will realize it's actually a pretty amazing tranny.
