TSB 12B37 - New?

[ChrisRo]

I just started noticing some weird shifting stuff today from 1st to 2nd at really low throttle positions. I thought the roll-back thing wasn't a big deal, but noticed it wouldn't do it on serious inclines, only slight.

I have faith it's in the trans calibration. Build date 10/10/2011. 500 miles on it. DCT SEL hatch.

Fingers crossed, this may put to bed the main concern I've had. My Ti build date is the week of 5/7.

We were your guinea pigs.

Anyway, you should be happy with your car.

I'm at the dealer right now getting this done.

Lots of us will be interested in exactly what software they update and if you feel that it made a difference, please keep up posted on the outcome

I'm back, it took an hour to do.

The dealer pulled the bulletin and let me read it.

Here is the jest of what I read;

Intelligent Oil Timer is to be reset; I'm guessing this is to fix the premature indicator that you need oil changed or result of it not telling you.

TCM reflash to resolve jerkiness and rough shifting, resolve the roll back when transitioning from brake pedal to gas pedal.

ABS reflash did not specify why; I couldn't find anything in the bulletin about it.

I feel it made a big difference. My transmission is a lot smoother than it was and now it doesn't roll back on an incline as if I had a manual transmission. I like it. I just hope it stays this way because the jerkiness was annoying the piss out of me. I don't have any shudder, never did, so I can't comment if this will fix any shuddering you may be having.

Sweet! I can't wait to try it out. What dealer did you take it to?

Covert Ford Hutto -- I'm still in Texas, won't be in PA until May 23rd.

Checked etis, it's listed with my car too. Hmmmm.

It still also lists that I need the MFT upgrade and warranty extension even though I did it myself through syncmyride and reported it over a month ago.

May have to check this out. Mine is a March 26th 2012 build, about 900 miles so far. Most of the Hard shifts are from 2nd to 3rd gear. Really hard jerk, the whole car shakes. Getting really pissed considering I would have though this later build would have been immune to this shifting.

I still think it has to do with the computer not adapting from highway driving right on to stop and go (that is when most of the hard shifts happen in D, S or manual mode). Maybe this lastest TSB is a fix?

How do I go about bringing this up to the dealer. Do I just walk in to the service and ask to update the software?

Go to etis.ford.com and input your VIN in the "vehicle" section. It should show as outstanding FSA 12b37. Print that page and take it to your dealer. Experience has been it's unwise to assume a dealer will know it exists.
