2011 v6 auto tranny problem

[caligrown562]

I bought my car a couple months ago and since new the tranny has had a hesitation when first accelerating after start up. I have takin it to the dealer and they say normal. Now I am starting to feel like the trannys slipping. Sometimes while the trans shifts it will rev high then catch. And after it does that you can really feel it downshift till you come to a stop. Has anyone else had any issues like this? I was thinking maybe low fluid?

My 2011 v6 auto trans also has low gear hesitation when accelerating from a stop light. This has been noticeable since new (11 months old and 2,920 miles). Have not noticed any downshift issues when slowing down.
I would also like to know if the low gear hesitation when accelerating is normal for the v6 auto trans.

............take it to a different dealer and drive it with them to show the problem. Drive another one that is on the lot and show how the new one does not do this.

mine seems to do this under light acceleration too. i thought i may have read about a tsb related to this, reflash software maybe was the answer. i don't recall the thread. i was going to give mine some time and see what happens (only 1500mi currently).

OK, that is three of us with low milage 2011 v6 auto transmissions experiencing the same issue.
All have low gear hesitation in up shifting. I find this odd and should not be normal. Auto transmissions, you would think, should not have a noticeable hesitation between low end gear changes. My 2011 2LT is low mileage but early production. Don't know if production date makes a difference (built Aug. 03, 2010, took delivery Aug. 10, 2010.).
Would be helpful to have an idea what could cause this low gear hesitation before we run to dealers and ask to test drive other cars on a lot.

OK, two threads on Camaro5 discussing v6 auto transmission low gear hesitation.
Called my dealer minutes ago, have an appointment to drop off my 2011 2LT early this Saturday morning.
Will try to keep all of you informed.

[caligrown562]

Cool let us know what they say cause my dealer doesn't think anythings wrong and wont do anything till its leaves me stranded somewhere.

Thanks for keeping us all updated abaucom21. I hope your dealer is able to get this issue resolved for you.

Are you certain you are not feeling torque management in the trans. Mine feels like it it pauses between gear shifts; annoying but perfectly normal.

What did the dealer say abaucom21?

[abaucom21]

Just posted the message below on the other thread under general discussions and I will keep everyone informed on both threads. Just going to add another note here. On the other thread a transmission tune has been recommended. That is what the dealership is going to start with. I told them about Camaro5 and there are currently two threads on this subject (LOL) so it is not just me that thinks this low gear hesitation is normal. My dealership is proud of their excellent customer service so I trust them to give this issue their best effort. The hesitation is not extreme but it is noticeable. I have been driving mostly auto transmissions since I started driving in the 1960s and never "noticed" this type of hesitation on any other car. My Camaro is an early production 2011, but low milege, mostly driven short distances stop and go. The Camaro has a fairly sophisticated auto transmission and I find it hard to believe the hesitation between low gear shifts is normal when upper gear shifts are smooth. As I posted below, on the other thread, when I hopefully hear back from the dealer later today, will post what they have to say. Below is what I posted on the general discussion thread today:

Thought I would update. Dropped the Camaro off on Saturday and was told this morning transmission guy would look at it after he finished another job. OK with me as I was not planning to leave home until Wed. when I take my Riviera in for some minor (hopefully) front shimmy at high speed. Almost funny the Camaro is in the shop for low speed gear hesitation and Riviera going in for high speed tire shimmy.
I will post again when I hear back from the dealer.
Sad but true. I have had my Camaro for 11-1/2 months and we have never been separated for more than a few hours even though I sometimes don't drive it for five days at a time. I think I am feeling separation anxiety so I just popped a beer. That now means I won't pick it up until tomorrow even if it is ready to come home today.

I'm still voting for "its normal" built that way to preserve the transmission and ensure it makes it over 100K miles. Its really bad in the Cruze - but similar to the camaro.

[abaucom21]

Just got a call from my dealership service rep. They can not determine problem (if there is a problem) unless I test drive with a service rep.
Will pick up the Camaro tomorrow and will have the service rep drive. I know of two roads where he can floor it from a standing start and hopefully not get a ticket or hurt small animals crossing the road.
I was told the A6 transmission learns our driving style and adapts to that driving style. My driving style is that of a little old lady in stop and go city traffic for short distances to buy booze and groceries.
Perhaps the transmission hesitates, thinking I must be the delinquent grandchild, when I have the few occasions to gun it from a standing start and the next stop light is more than one block in distance.
I asked my service rep if they can reprogram this transmission to understand I drive like grandma most of the time, but occasionally want to drive like the bad grandchild. There was a long pause. He suggested my waiting time to test drive with a specialist would be only 20-30 minutes tomorrow. Hopefully I will be able to control my weak bladder before, during, and after my test drive. Have to check and hope I am not running low on adult diapers.
Of course, all of you know the car will have excellent performance during the test drive (LOL).
Still love my dealership. Only issue I have with this experience is that I told them this morning I did not want the $11 car wash as it was going to rain Monday & Tuesday. They washed the car. So I will have to ask for an $11 credit if I soil my white Camaro tomorrow during test drive.

[abaucom21]

Update: Picked the Camaro up Tuesday morning this week. The transmission check/service indicated nothing obvious or abnormal. So made an appointment to go for a test drive today, Wednesday. We test drove my car on some long straight roads and it was noticed there was some hesitation between 1st and 2nd gears, not as noticeable between 2nd and 3rd. We then test drove a new 2011 equipped like my 2011 2LT, A6. non RS. A difference was noted. As best I could understand, the shifting between 1st & 2nd gears on my car there was about a 400 rpm spike, however on the dealer brand new car the spike between shifts was only about 200 rpm.
Good for me, as I wasn’t told this is normal. So they called GM while I was standing there, confirmed no one else in North America has reported this issue, so they started a case file with GM. I am looking at my service receipt as I write this and it says, “Test drove with customer and confirmed shift flare between 1 and 2 at approx. 25% to 40% throttle opening. Will need to call Tac. Gerrald Pelly. Case 971102622. Suggest following document 1593292 and published S1 diagnostics.”
They will be ordering some parts and I will drop the car off Monday Aug 8th and leave it with them for the week (I am in no hurry & we have a Canadian national holiday early August). So don’t rush to your dealership as apparently I am the first in North America to get a case file started with GM on this issue (LOL). Not a big issue, but an issue nevertheless I wanted addressed at some point in time. I have a wonderful dealership and trust them 100%. They could have told me this ‘flare’ was in a normal range and I would have believed them and just considered normal for this transmission. Instead my dealership is putting in some time and effort to see what can be done.
Just wanted to say I have learned much from people on Camaro5, and perhaps, my sharing this information will help a few others on this site. No issue is too small or too rare to discuss and I most likely would not have taken my car in for many more months to have this issue addressed, until someone else on Camaro5 opened a thread and started the discussion. I will let you know the outcome hopefully the week of Aug. 8.

I just dropped mine off at the dealer for the rev spike between gears. I have also noticed some strange things when going uphill at highway speeds(car does not downshift, but RPMs fluctuate in a sinusoidal manner, etc)

[caligrown562]

Hey lifebysong. Please let me know if they find anything out. I am still experience the same thing. Thanks

[Chevrolet Customer Svc]

As caligrown said, keep us updated on how things go for you with your dealer. Hopefully it's a quick fix for you.

My wifes 2011 LT was having same issues only 3800 miles on her car. We brought it in today for an oil change and there was a recall (11160 loss of air condition - reprogram BCM Module) they test drove after the flash and the trans guy said everything was normal. They could not tell me if the flash bcm program had any other updates or a higher version than what she had.
BUT She pulled out on the road and lit up she said she has more power and smoother shifting now than before. Happy Wife with Happy Camaro = Happy Hubby

[ACE@GSO]

Thanks for the posted updates. I thought I was the only one with this issue.
(2011 LT1 RS) Bought in February at Charlotte, NC.
Right away I noticed the 1st to 2nd gear shifting vibration, usually at 43 mph.
At 1st oil change, (May) the dealership they told me it's temporary vibration it should go away before 2nd oil change. At 2nd oil change (Sept), I complained to service manager and he called GM and he told me GM is aware of the V6 transmission problem. Many Camaro owners are complaining.
GM is working on it and hopefully they will issue a recall soon.
I'm schedule for the 3rd oil change and I will continue to complain until they fix it..
DON'T BELIEVE SERVICE TECHS if they tell you it's a normal transmission vibration.

I purchased a 2011 Camaro a couple of months ago, new (left over I guess) it had a couple hundred miles on it, but it was exactly what I wanted and the price was right. I love the car, I have less than 3000 miles on it and yesterday the transmission started slipping and didn't want to move after I had stopped. I was close to home and it started to work so I limped it home. This morning I drove to work ( about 1 mile away) and it was slipping so I called gm customer service and they sent a tow truck after it. I will post more when I find out something from the dealer.

[JQUICK]

V6 Auto vibrations here. Any updates? My dealer said he couldn't replicate the issue.

[JQUICK]

Heres the issue for most people. TSB is on page 9 with the pic of it.
