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.

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?

ZR2 and I'm in love again!

You got some actual pics? Ive heard terrible stories about the trannys in those. But, no vibrations at all?

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.

    • First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.  
    • I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
    • There was a recall on the tailgate in general for opening on its own. Mine has a cap on it and it won’t let the tailgate open.   My tailgate has two holes in the top of the tailgate. I filled them in with silicone sealant.
