As discussed in a previous post. I went to my local 4WP and they told me about an issue they came across. Apparently on the 2WD trucks, the Automatic Transmission Extension Housings is damaged or not properly installed from the factory. The seal leaks (transmission fluid) and/or wears out prematurely and this causes .... wait for it ... our dreaded shake with the 2WD trucks. Definitely something fishy with the transmission and drive shaft. This has worked so far on a GMC and Chevy. The part number is ACDELCO 24224676. $75 for the part plus labor. Did it fix my shake? About 80% there. I can now get up to 90 MPH without the console throwing itself violently. Unfortunately the shudder between 30 and 55 MPH persists. I still have wheel hop, so that is probably attributed to the crap axles and the trash leaf springs. Good luck YMMV.

Thanks for the info. I found a GM service center that knows about the problem, but they have to go through GMs procedural crap. The shudder between 30-55mph is the torque converter. GM tech told me that himself. I'll keep this updated in case it helps anyone out. They'll start working on my truck next Tuesday.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

what about 4wd ? same problem ?

 

the problem with this vibration is an expensive fix to recall and apparently not life threatening or causing damage beyond uncomfortable ride

 

it may be expansive due to time or labor or parts no one can tell but GM .

So far this has only been performed on 2WD trucks.

The 4 wd has an adapter where the 2wd tail housing would bolt that connects the t-case to the transmission. It's just a hollow piece, not to say the t-case doesn't have issues at the intergrated tail piece where the drive shaft conncets. If that really is the issue it explains why GM doesn't want to fix it. 2 grand a pop plus labor for the t case.

Well, I'm out.

 

Traded the GMC in on a new truck and I am very happy about it.

 

Good luck guys - I really, really, really hope we do end up finding a solution...

What did you get?

I've heard the same thing, that they are having transmission issues. A friend of mine encountered a lady that couldn't get the key out of the truck because the truck thought the tranny was in gear when it was in park, couldn't start the truck either because of the same reason so he hit up another friend that's a mechanic and he said the colorados and canyons have been having a lot of transmission issues.

Thinking of trading my 2014 in on a 2010. Pretty sad when you look to downgrade 4 years because you know that era of truck is tough as nails and typically issue free. My 15 is my favourite truck I ever had, the 14 is my most hated truck I have ever had. Case by case basis. I think it a combination of cheaply manufactured torque converters, driveshafts, and rear axle shafts being made by 6 y/o kids in China. They build them cheaper and cheaper and charge more and more. Anyone with SLT's or Denali's shaking, or mostly the lower trims? My SLT is like silk but this WT is like your driving down as highway made of railroad ties.

900's were a step backwards from 800's the K2's are a far superior truck so your actually stepping backwards farther than you think....

So I am finally rid of my shaky truck. I went through the BBB process and it was extremely easy and straightfoward. I had detailed notes of each visit, with who I spoke to, tech names, etc and it proved very helpful.

 

It was comical how GM attempted to defend the truck. I won't get into details other than the fact they told the arbiter this was their first ever complaint about the vibrations. I almost fell out of my chair.

 

Anyone with a vibrating brand new truck should definitely go through the BBB as soon as they hit their state lemon law requirements. I was awarded a full buyback minus mileage that I had put on the vehicle.

 

Never again will I own a GM product and I have been extremely impressed with my RAM for the first month of ownership. GM consistently lied throughout the entire process and was a complete pain to deal with.

 

Good luck to all and if you want any more info about the BBB process just send me a quick message

Actual pics? Those are actual pics of my truck...

 

No, zero, zilch, nada vibrations at all and the transmission is working very well. Granted, it has 288 miles on it so far but I actually really like the 8-speed for shift quickness. I think it doesn't suit some peoples driving style but I've had no trouble.

I can't believe you said that. The 900s are by far the best generation truck GM has made. I went from an 09 to a 2014(worst generation) back to a 2009 Avalanche.

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
