Chevy Silverado and GMC Sierra Transmission Problems

Comments

  • I have read the last page of this topic and comments about only a few negative posts.I am sure that does not equate to the actual number of owners having issues with a clunk in the power train.
    #1, as one person stated,"how many people are aware of this blog"
    #2, it takes time and effort to register as a new contributor to any blog(I almost did not because of that)
    #3, There is no benefit from investing time and effort since after reading some of the blogs you have already found out that
    a) you do in fact have a brand new 2011 silverado 4x4 with 5.3 v8 and 3.42 rear end with 1025 miles that OCCASIONALLY clunks
    b) lots (probably most) of people with these vehicles have the same issues
    c) GM is very aware of the problem
    d) GM so far is not dealing with the issue(maybe it will go away-head in sand tactic?)
    SO as a new entry to this blog THAT IS MY 2 CENTS!!!

    My concern is what damage is taking place when the clunk occurs. STEEL on steel clang,clunk,bang is NOT good no matter how the problem is attempted to be minimized.

    Any one who has driven a stick shift rear wheel drive vehicle with a worn universal joint knows that once you start hearing that clunk that it only gets worse until you are forced to replace it.

    Also, if you ever had a gear in the rear end break a tooth you get very loud clangs.
    So that is what my concern is.What damage is being done and where?

    If anyone out there has SPECIFIC information on damage I feel that is what we should all be trying to identify.
    With only 1025 miles on my Silverado I am concerned that I made a HUGE ERROR investing in GM again

    There have been zero reports of damage - so your theory about that aspect is incorrect. There are people that have many,many owners that have more miles than you , and while their trucks do "clunk" at times the truck otherwise runs well.

    There have been zero reports of damage (the clunking at this point doesn't seem to lead to the rear end needing replacement or the like)- so your theory about that aspect is incorrect.

    chuck1919,

    My point was that I do not know if damage is occurring or not when you hear the clunking. Clunking is usually two pieces of metal banging together. For example, if two gears are meshed together properly there is no slop or gap between the teeth but if there is too much gap or slop between the teeth you can get a bang or clang type noise when the slop is taken up when you apply power to the gear train.That is why there are specific tolerances for gear to gear contact.
    Also I am only guessing the clunk that I hear is coming from the rear end,it is definitely from the back end somewhere.
    And so far the clunk has only occurred 4 or 5 times but since the truck only has 1000+ miles it had me very concerned and that is why I am spending some time researching the issue.
    You said there have been no reports of damage.I am curious how you know this.
    As far as any theory, I DON'T have one. I'm searching for information on whether I SHOULD be concerned or not.
    My only previous experience with noise any where in a vehicle was that it always was a problem in the making.
    Thanks for your reply chuck

    It's not necessarily the rear end. It's the binding of the drive shaft due to building up of the torque in the power train. IF you do more research you will find this out. How do I know there is no rear end damage? Because it would be all over the Internet as is this clunking thing is.

    There are vehicles out there with well over 50,000 miles on them with no rear end (or rear end noise) concerns. When you have gears off spec or a bad bearing in the rear end you know it.

    It is exactly posts like yours that has made me get involved in this board. It's OK to have fears about clunks in a brand new vehicle, however the sky IS NOT FALLING and your Silverado will give you many miles of service. And in the event it doesn't you have a 100,000 mile powertrain warranty!

    BTW-GM sold 45,000 (combined GMC/Silverado) last month. You don't see these things at the side of the road broken. Therefore, drive it and don't worry about it.

    chuck1,

    Thanks for your reply. The mystery of the cause for the clunk will still require inquiring minds to search for answers but I certainly appreciate your information about the torque build up as a possible cause. You are right that it would be all over the internet if the clunking resulted in broken parts.But in the short time that I have spent researching the problem(only today) I have seen the CLUNKING issue discussed on a lot of internet sites. Apparently the clunking is associated with a variety of locations in the drive train depending on each power train configuration.
    So yes I will worry less. I have to assume you are associated with GM somehow or just a dedicated GM owner.But that is none of my business.
    Thanks again for your input I will probably not post again unless I have additional information..
    worriedtoo...(maybe less)
  • Has anyone experienced a whining or whirling noise in first gear on these six speeds? I traded in my '07 Silverado for a 2011. Never heard this noise with my old truck.
    I was told it was normal. Of course. Guess I got 100k miles to find out. I know it's the new coporate way to cut corners and go with cheaper materials and charge more for it. I was comparing my '07 window sticker to the 2011: 90% US/ Canadian parts on the 2007, 61% on the 2011. Sad.
  • well. I have a 2010 sierra 4 crew cab 4X4 and I have had it for a year. I have decided to cut my losses and sell it. I know I will loose but it's not worth keeping it long term as I hate driving my truck. It's looks great, but don't drive it.

    Good luck :)

    We finally know that CHUCK1919 and CHUCK1 are one and the same.
    The way you know about any complaints chuck is because you ARE employed by GM.
    A "happy" truck owner is not going to hang out on a forum discussion, provide the inside info that you have, continually spout the sales numbers, and bad mouth a post describing problems with their vehicle.
    you are here to discredit any conversation that GM doesn't like.
    and they don't like conversation about their truck problems that they refuse to address.
    I had my truck in service at a new dealership and still get the same answer...operating as designed. BS

  • Guys.... I think we all know "Chuck" and his goals on this forum. I discredit all and any responses from "Chuck" of any sort as they are bogus replies and he should disappear from this forum. We are know in today's busy economy and all if we had no issues with our GM vehicles that we would be doing something different than posting topics of dissapointment in respect to our vehicles. GM will and is going to do nothing about our clunks/ bangs/ squeeks or whatever is all wrong with them until these issues pose a safety concern.

    I am not a GM employee. I am however an owner. The guys that are unhappy have every right to voice to concerns regarding their ownership experience. However, spewing have truths about their vehicles or GM is not satisfactory.

    When I see a half-truth, or a statement that is not accurate I will respond.

    You have one guy on this forum spewing hate against GM because he was sold too much vehicle and should have never purchased a truck for a "grocery getter" and his says GM stinks because he is driving about a truck that weighs two tons and his gas mpg stinks. You don't buy a truck for mpg (regardless of manufacturer)...that's for sure
  • chuck1chuck1 Posts: 1,405
    Sorry but if keeps "eating at you" you should sell it. I have told others the same thing. Let us know what you end up buying and what they gave you fro a trade. I would expect your looking at no more than 20K for a trade in.

    Good luck!
  • Chuck1
    I rather have a 10K loss than a 55k total loss. But this is my last GM. It's not your concern what I purchase, but for sure, I will more diligent in my purchase. I made the mistake of assuming that because I had such a great truck before, that I would have an even greater one. I can bet you there won't be any clunking noises or, lag of power, or AFM issues, or sudden down shifts coming at a stop.

    You know, the GM stance of "it's operating as designed"! When you design crap, it works like crap. It operates as designed.
    I wish I had my old truck again. I was told once they put allot of money and engineering into this. Obviously not enough. They rushed the product out. And lastly, the old saying about they sold this many trucks this month. Please, Ford had the number one selling truck for years, and it would rust just by looking at it. Numbers don't state anything apart from people getting the best bang for their dollar. What is the best valued purchase for that month.

    GM owner or not, does not matter if it was a Ford, GMC, CHEV, Dodge.... I would not put up with any of the problems I currently have with my GMC. And believe me, I am very vocal about GM's poor quality regarding trans and I tell them out right, don't purchase a GM. :mad:
  • U tell em Pete- ha! People think it is fine to spend thousands on a truck; drive it away from the lot, lose an instant 30% and then more when you trade it off because you were really disattisfied with it. We are stuck with the crap unless we want to take a butt whipping and dump it. Well, as long as my pile of bolts gets me to and from work- I will put up with it. Conversation is over. Hugs and Kisses Chucky! :lemon:
  • chuck1chuck1 Posts: 1,405
    Your right it's not my concern what you purchase. However, I was looking for a comparison once you made your purchase. That was my only point.

    If you don't wish to provide a comparison, then that's your business.

    Good luck on your next truck.

    I have been following all the complaints which I my self had as well on my 2011 gmc and feel ashamed that gmc hadn't done anything about it.
    My question to you and to all the people complaining especially in the US, can't you escalate the issue to an official federal establishment? I can understand we in Saudi Arabia CAN NOT, but you in the US should be able. I remember back on 1986 buying a camera in one of the states and when I was not satisfied with it after two weeks of usage I was able to return it with full refund.

    Anybody here in the states can go to NHTSA (http://www.nhtsa.gov/) web site and lodge a complaint whether it's real or imagined.

    If the gov't feels it's warrantied then an investigation starts. Adeem, there is only 14 people complaining on this website. I am afraid that's not enough to start an investigation.
  • i believe that gm, a.k.a. "GOVERNMENT MOTORS," SHOULD BE obligated to replace or repair any or all vehicles with transmission problems because of the faulty engineering design of the 4L60E, focusing mainly on the 1999-2001 2WD silverado or sierra. i myself am on my fifth transmission because they still haven't developed a rebuild kit or modification for its shifting problems. i mean christ sakes, have they ever heard of a factory recall? all the other motor companies will stand behind their products and take responsibility for their mistakes. why not GM? too many of these trucks HAVE THE SAME ISSUES. IT IS NOT MISUSE OF THE OWNER, IT'S IRRESPONSIBILITY OF GM.

    I have since paid for my truck twice because of this issue. However, during the time i made my purchase I was unfortunately misled into thinking this was a great decision on a good trusting truck. To me this falls under the same category of "FALSE ADVERTISING". Then again, your slogan like a rock did state its reliability as far as getting you where you need to go. Last I checked a rock wasn't very transit!

    1999-2001

    So you want GM to fix trucks that at average miles driven per year (15,000) would make them have 150,000 plus miles on them. I don't think there is an auto manufacturer in the world that would do that.

    In addition, if that were my truck it would have been gone after the second transmission issue, if what you say is accurate.
