TSB 12B37 - New?

dberezin · May 10, 2012

I'm sitting here at the dealer now having the update applied. Keeping my fingers crossed that it's going to fix my issues.

As a side note, there is a beautiful black Shelby Mustang GT500 sitting here. (wiping up my drool)

I have my 10K km service appointment this saturday, I'll let you know it this 12B37 recall applies for foreign markets

Even though this one doesn't apply to me it's great to hear you guys seem to finally be getting some resolution to your transmission quirks.

That it is! I have mine scheduled for the wiper work and 12B37 this coming Wednesday.

It may be in my head, but S mode does indeed feel more aggressive.

I hope so ... while my DCT has been good to me, the S mode always seemed like it could have been more aggressive.

I got my update today. Of course I knew more about it than the service guy did. I explained it was to fix issues like vechicle roll back on inclines etc. He then put that on my service sheet that I was having an issue with rollback. When I got my service receipt it stated that rolling back on an incline was a "normal function". He obviously had no idea what the update was for or what it did.

Haven't had a chance to see if this update fixed the issue. It may all be in my head but after the update I seem to get better throttle response.

dberezin · May 11, 2012

Here's my update:

I still have some shudder when letting my foot off the brake. It seems to happen after the car has been driving for a while or if I come to a quick stop (like sudden traffic on the PA Turnpike). I'll see what happens after a 1000 miles (which will be a couple of weeks for me). Has to do the adaptive learning again.

The shifting seems to be better, though, especially when going from 1st to 2nd and 2nd to 3rd. When making a turn (slowing down for the turn, then pressing on the gas) it seems to be a lot smoother. So far I haven't had the "pause and lurch". It also looks like it's holding the higher gears a little longer to get better acceleration.

Haven't had a chance to test the rollback fix.

Loving the update so far! It seems to shift smoother than the 12-01-04A update (I didn't even think that was possible...) and I like the shift pattern in drive under moderate acceleration better; it seems to make more efficient use of the gearng to me (shifting at 2,500 as opposed to say 3,000) but without a feeling of lost power. I haven't done much sport mode driving yet.

I couldn't have said it better. Agree 100%

I'm not sure if you're talking about the shuttering when you depress the brake on a very hard stop... if that's the case it has been confirmed by a few ford mechanic to be the ABS.
The same can be said about the sharp turns at high speeds, the system applies the ABS brakes on the inside turn wheels to give it a sharper turn.

I've never experienced the shuttering when letting go of the brakes though. Only light gassing at low speeds inbetween 2nd-3rd gears, like a new manual driver would incidentally do.

But after the update, there is a huge difference, though I think it'll need to do some minor tweak and learning for my driving habits.

12B37 Update May Affect A/C.

I posted this in the main DCT Update thread, but thought it should also be in this thread:

I took my 1/31/2012 build Titanium in for the 12B37 FSA yesterday. I wasn't having any trouble with the DCT, but thought I would get it done since I also had a speaker rattle in the rear doors. On the service receipt it says "Completed Recall 12B37 by reprograming PCM, TCM and ABS. Also did IVD calibration, 7485 12B37C reprogram PCM and TCM." (I have no idea what the IVD is???)

When I picked up the car, I stopped in the dealer lot to see if the speaker rattle was gone (it wasn't....they're ordering new door panel clips) but I noticed the A/C was blowing hot air. I drove back into the shop, they took it in again. After about an hour, the service rep came out and showed me a communication they had received from Detroit in response to their query about my situation. Ford apparently has had reports that this FSA can cause the A/C to stop working. They recommended the tech take the car out on the road and run it at 1500 RPMs for three minutes. He did this and phoned in to the shop to say that at exactly three minutes, the A/C began blowing cold air.

It was kinda weird but fortunately, not a big problem. When you get the update, just make sure your A/C is working before you leave the dealer!

BTW, although I wasn't having any problems with the DCT before the update, it does seem a bit smoother. I've got to drive it a bit more to see if it really made a difference in my car.

I had it done today and the transmission is smoother, and the shutter is noticably reduced. However, it still makes some grinding noise. I will give a chance for the transmission to relearn itself. If it does not go away by 15,000 miles, I will have a talk with the dealer. I have 10,600 miles on the car now.

Focusinva · May 12, 2012

I just noticed today something that was absent prior to the update. Before I had the update I had no visible or audio warning when my seatbelt wasn't fastened, which I thought was odd....now it blinks, yells and screams at me as soon as I put it in drive with no seat belt on...obviously it supposed to do that, but now I'm wondering why it didn't do it before.

RedoFromStart · May 12, 2012

The point in buying a brand new car was to not have to take it into the shop, leave it there all day, arrange for rides to/from work, be without the car, etc. This makes twice already and I've only had the thing 2 weeks. Not the way to impress. The update is fine, it's the service department I'm weary of.

red2009se · May 12, 2012

I'd the FSA done in 45 mins. Dealer was actaully not busy on a Saturday afternoon, but maybe people were getting Mom's Day gifts instead.

bsp_53 · May 12, 2012

Richs10 ...
Thanks for the detailed post. I'm hoping Wednesday's trip into the shop will be the last for a while. [cheers]

ccelaya · May 12, 2012

I just came back from my 10,000km service.
They didn't have any 12B37 listed in their system (Mexico), but got the 12-01-04 TSB instead. Maybe I'll just have to wait a couple of weeks until it's released here... the car shifts better than ever though

Oh, and I also had the 12-02-17A, 12-02-17B steering gear TSB parts ordered for me.

Quoting myself from the DCT / PowerShift Transmission Update TSB Thread...

After hearing about some of you guys getting the 12B37 done this week and getting the response above from 1 dealer, I decided to call another dealer near me (Bill Marsh Ford in Newtown, PA) and ask them about the FSA. He put in my VIN and told me my car was due for the update. I'm bringing it in Thursday night to have it done. Hopefully it can fix the shudder issue. [giddy]

I'm still amazed at the ignorance or complete lack of education of some dealers with regards to this car. To me it's either Ford not communicating down properly or laziness of the dealer's service groups in not doing their homework. I tend to believe the latter. I qualify this by saying my original dealer's service manager fought me at each turn in attempting to get the December update done to my 5/11 build while another dealer some 15 miles away knew of everything that was going on with this car and was willing to assist me should my original dealer not want to or simply couldn't.

While since the update in January mine is far better than the original, there are still issues (mostly attempting to get up to speed merging onto an interstate - it seems to hunt for the right gear or the original programming was so bad it took out one of the clutches). I'm hoping that this update will solve this remaining issue.

I'm calling the "other" dealer tomorrow for an appointment.

Got this update earlier in the week.

Awesome.

D works much better, much smoother. I like it completely now.
S is like a rocket, especially if you turn off traction control.

MPG is the same for me. Then again, I've been zooming in S.
