Are there any Automatic Transmission flash updates available since 8/31/2011?

Wondering if there are any newer Automatic Transmission flash updates since August 2011?

Have a 2011 Cruze LT and still not thrilled on how it acts. Drove a 2012 and they seem better.

Dealer is no help...



Thanks.

I asked the same question on another thread and nobody answered. Mine is a May 2011 build. I saw there was an update to an earlier flash, but it was marked June 15, 2011. I'm wondering if mine would have already had it? Yours couldn't have been built in August, or it would be a 2012. What's your build date and have you flashed it once already?

I'm interested in this issues. AT PCM of 2009 version is very lag, but there is no flash or update for this in our dealers.

Mine was built the last week of April, 2011. In August, 2011 my dealer checked and said that my transmission was flashed
with the most current update available. If that is the best that Chevrolet can do that is pretty sad...

Shoot. It looks like mine must be the latest update, too. I was hoping for slightly better performance, too, but I'm ok with the way it shifts now. It's way better than the Focus my friend owns.

Last week, I e-mailed Chevy just to ask just when, in the summer, the new Spark would be at the dealers. Evidently, not many people have inquired about the Spark because I got this e-mail back from them saying that they were "ecstatic that I was a Chevy enthusiast..." etc.

Well, I e-mailed back and told them not to get too excited, then I told them a few things that were on my mind about my February 2011 Cruze LTZ RS especially the transmission. I only have 9,300 miles on the car in 17 months. I felt good after I vented and figured that I would never hear another word from them because their e-mail "customer service" is outsourced to companies that have nothing to do with GM.

Was I ever surprised when I got a call earlier this week from someone at GM who was concerned about my Cruze issue. I told him how I felt about everything from the 4 million mile testing to the sloppy hacking of the drip pan to the coolant smell that many were complaining about! I told him I was amazed that none of these problems showed up in their 4 million miles of testing. I told him that my dealer said that there is no new transmission update and they just kind of shrug when I mention the crappy shifting. He asked me to stay on hold while he contacted my dealer. He came back on and said that the dealer told him that the last time I was there with the Cruze was February for an oil change. He wanted me to make an appointment to bring the car in to the dealer. I told him that if I drove on the highway every day and the transmission didn't have to shift, I would have no complaints because my tranny is the only issue, besides the lousy gas mileage. However, my driving is rarely highway, so shifting is in the forefront EVERY day. I also told him that the things it does are erratic and that someone driving it for 5 minutes might not notice a thing. I told him that they have to keep it and drive it locally, in traffic etc. for a longer period of time than 5 or so minutes. He told me no problem, they would get me a rental car.

So, I went to the dealer that is only 2 minutes away and made the appointment for that, the recall and an oil change. It goes in tomorrow morning. IF they fix it, I will post it here for those of you still experiencing shifting problems. I SHOULD have mentioned to the GM guy about that "tune" that people here have done to their car and solved their transmission shifting problems and see what he says. If this is a procedure that can be done by an outside soiurce to solve the problem, WHY can't GM do it to solve the problem? I'll have to make note of it to remember to ask him.

In the meantime, I just went outside to take some before pictures of the oil shield. Let's see what it looks like after they get through with it. However, they may do a good job because I have already informed them last week, when I brought my 2004 Aveo in for service, of the hack job pictures that I have seen here. Let's see if it makes any difference.

One more question- does the coolant level look like it's ok? It looks low to me?

Here's what the workorder stated about our '11 LTZ transmission "service":

C/S engine surges/lacks power at times when driving or takes off...inter(mittant)...any temp(eratures).
Duplicated concern. No DTC stored in engine or transmission.
Performed transmission Adaptive Learn Procedure and Self Cleaning.
Now operating as designed.

Wife is driving it now, we'll see if things were fixed or not.

Anybody know anything about this so-called "Adaptive Learn Procedure and Self Cleaning" reprogramming?

Sounds about the way mine acts. Several times it has BANGED into a gear when shifting. It's done that about 4 times. That is so rare that they'll never find that. This- "Adaptive Learn Procedure and Self Cleaning"- sounds like they erased what it "learned" and set it back to day one? I was going to ask if they could do that to mine before this guy from GM called me.

I've been thinking about this as well, I wonder if disconnecting the battery for a few minutes would reset it.

The ONLY other car that I ever had with a crazy "learning" transmission like this was my 1999 Chrysler 300M. People used to pull the TCM fuse for a certain period of time to reset the tranny to day one. Don't know for sure if it really worked.
