DCT / PowerShift Transmission Update TSB Thread

[Titanium12]

They did the test drive for me and had it relearn itself, however, I think they normally let you do it and just remind you that it will shift kinda weird while it relearns itself.

One question I do have that I brought up to the service advisor when dropping it off for the update is that when I have it in sport mode......it will shift on its own really early sometimes.....like around 3500-4000 rpm. (& it still does after the update) Anybody else do this?

Awesome. I just called my dealer's service department. They're going to take a look Friday morning for me.

Hopefully this gets applied!

Perhaps someone can offer some insight as to the noticeable differences between the December and October TSBs?

I can't yet, but I'll let you know once (if?) I can find a dealer that'll do the TSB for me.

It seems that some fine tuning was done. It is definitely not a night and day difference.

The previous calibration was smooth but the clutch engagement always seemed a bit "soft" to me. Under certain circumstances, the RPMs would drop too slowly during some shifts (i.e. excessive clutch slippage).

I just did the update yesterday so I will give it more time before reaching any conclusions.

Well got mine done today. I thought to myself, what if they didnt do it cause they said it was ok, or worse they said they did do it, but really they didnt......Well that was before I drove the car. I could tell right away that they did it! What a difference! Shifting is alot smoother and rpms are a bit higher.

I also noted the Test menu before and after the update and a couple codes did change. They are: under APP it was BM5T-14CO26-AK, now its BM5T-14CO26-AP also under NVM EEPROM it was 17.m8 now its 19.101.

I'm not sure if the above changes relate to the transmission update or a gauge calibration update they did. He said the calibration update should fix the fuel guage error i got when it was cold outside.

Forgive my total, um, stupid question... but I assume you're just saying smash the accelerator to the floor from a stop a few times... right?

My build date is Dec 2nd so I'll be asking the dealer to check into this when I take it in this evening!

A few full throttle acceleration runs from a stop is the suggested remedy. As the issue in question seems to be the first gear clutch, there's no need to accelerate to much more than a modest speed.

If you're pretty happy with the way yours is running, I don't know if I would recommend the update. As mentioned, I thought pre-update test cars I drove performed better.

As an aside, mine came off the trailer with 100 miles and a note from Ford that it was used for test purposes. Must've been one of the first off the line with the new software and was tested for that reason. Surprised it passed.

Out of interest, is this exhaust note the shift pattern of a full throttle pre-TSB in D?

My Focus was built post-TSB, so I can't tell for sure, but that shift into 3rd sounds a good deal earlier than mine does (in D). I'm not sure I'd be happier with a shift that low in the power curve.

Got mine done tonight. Will report back.
