Shutter during acceleration - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

DALLEN260 · 07-26-2012, 05:41 PM

Just wondering if anyone else has experienced this. When cruising at low RPM, between 1500 and 2000, upon slight acceleration, the car has a shutter or shaking feeling. If I press the accelerator, the car down shifts and it goes away and pulls as it should. It only happens with very light press on the gas. BTW, its a 2012 2LS and I will be taking it in for service but just wondering if anyone knows what is causing this. Thanks

Iwantone2 · 07-26-2012, 06:52 PM

LS3 or L99?

cjon9657 · 07-26-2012, 07:12 PM

My camaro does this, it has something to do with the torque converter. i hear of guys getting their torque converter replaced under warranty and then a month later it does it again. so rather than me do that i just live with it until GM decides to do something about it like building a little better torque converter. just my opinion.

yoomoogoo · 07-26-2012, 07:16 PM

I have the exact same issue. Usually happens around 30-45 mph. 2012 2LT/RS

Blue10CamaroSS · 07-26-2012, 07:16 PM

I get it too everyone once in a while on a light take off. Rather then pressing hard on the accelerator, i press lightly, and it feels like the car stutters until i pound the pedal

Mikeb12 · 07-26-2012, 07:23 PM

i have a 'stutter' at about 1650ish with light throttle (ls3). to me, it feels like fueling. Because the rpms sit right there in top gear at 65ish, I am guessing it is lean spot for emmissions testing. no doubt the flaw could be tuned out with a mapping.

Coyotekiller · 07-26-2012, 09:11 PM

That would be the car bogging down. You aren't pressing the gas enough to make the computer downshift the trans, so it bogs the motor. Put your foot in it and it should shift down to an appropriate gear. I'm not sure this is a problem, more of just possibly a quirk of the car. But there again, I had the LS3 so I don't have a computer to shift for me.

Aries240SS · 07-26-2012, 09:23 PM

2 issues in this thread... 1, the converter stumble in the L99 cars, and 2, the short stutter in the LS3 usually caused by a vacuum leak.

Count me in as well.

yoomoogoo · 08-02-2012, 01:51 PM

So I took mine in to the dealer today. They had the technician drive it and he could not detect any shuddering.

They told me it was fine. It clearly is not fine. The shuddering continues. Could use some help from Chev. Customer Service.

Earnhardtfan77 · 08-02-2012, 02:27 PM

hmmm...i have not noticed this...i will have to give this a try the next time i drive my car

camarograna2 · 08-02-2012, 04:07 PM

Hey guys sorry for the ignorance but what is shuttering. Im having something similar i guess. http://www.camaro5.com/forums/showthread.php?t=241294

When your around 30-40 and you slightly press on the gas it downshifts and feels like it bangs. it feels hard like if its banging into something. Dealer claiming it is because of adaptive transmission shift. I asked them to reset it to see how it feeld.

Your car will feel like it is riding over rumble strips in the road. The car will feel like it is vibrating. It is not a noise or droning sound.

camarograna2 · 08-02-2012, 05:04 PM

k thanks.. then no i dont have that.. i just have a bang when it downshifts. Dont know who is in worst shape :(

trganey · 08-04-2012, 11:57 AM

I have the same symptoms with my 2012 V6 Auto.

Mine was/is the converter and will be changed on Wednesday of next week. We'll see how it goes

bucketlist · 08-05-2012, 09:10 PM

My 2012 2LT v6 is doing this. Took it to my Dealer last week. Got the old "unable to duplicate customer complaint, vehicle operating to manufacturers spec". Insisted on having a tech ride with me. Got it to do it slightly but he said he didnt think it was bad enough that GM would replace the torque converter. Actually told me to see if it gets worse. Just what you want to hear on a new car, "drive it and live with it till it gets so bad you cant stand it, then we might do something about it." Sounds to me like GM has a problem that they dont want to deal with at this time.

Thanks Brandon, that would be awesome. Definitely a newbie here on the blog. Is there a way I can send you my personal data as a PM? Not sure how to do that.

Thanks,

DALLEN260 · 08-07-2012, 11:45 AM

Just thought I'd update you all. I took the car in to Jupiter Chevrolet and went straight to the service manager. I explained the problem and asked him to check for service bulletins. He found the document and sent a tech to diagnose with me driving. I duplicated the shuttering and while it was doing it, he commanded the torque converter off. The car immediatly smoothed out and no more shuttering. Long story short, the converter is going to be ordered and replaced. He did tell me that there has been a part number change so they are replacing with a different converter. I'll update again after it has been replaced......

Nvincent4708 · 08-07-2012, 11:52 AM

my brothers lfx is having this issue

it was diagnosed to a torque converter..which is back ordered. he is having to wait 4-6 weeks for one.. which is unacceptable.
