  1. Yeah this is the issue I have with these trucks. both my 14 and 16 started out smooth as butter but as miles were put on the hard shift from 1 to 2 showed up and progressively got worse. Sometimes to the point at low speeds in say a parking lot the shift was so hard it was as if someone rear ended the truck. Non of the GM truck/suv products I have driven in that are 2013 and earlier showed sings of this clunk. It just doesnt speak longevity to me but i am not a mechanical engineer so I cant say one way or the other on that.
  2. I know GM says the low gear transmission clunk is normal its just that when you pay what we pay for these trucks I plan on keeping it for a long time. The clunk in the transmission does not give me confidence in the longevity department. If the new 10 speed mated to the 5.3 does not have any of this then there is a good chance I pick up another GMC.
  3. Thanks for the info, i knew you could get the 5.3 in the 10 speed but didnt realize that wasnt the case till just recently so reviews are limited if any.
  4. Hi all, Trying to keep this short, my 2016 All terrain was stolen so I am in the market for a new truck. I am still hesitant on getting another GM truck due to them being the number one stolen truck from the lists I have seen but it is really difficult to find something with the tech and mileage these trucks offer. So I have been looking around on the forums and since the truck is new i have not seen much for sticky threads related to the issues I have questions on. Coming from a 2014 & 2016 AT 6 speed and 8 speed 5.3 my questions are below as both trucks experienced the same issues. Has anyone with the 10 speed mated to the 5.3 with decent miles experienced any of the low gear hard shifts and throttle hesitations that a lot of us (everyone i know personally with this truck) have experienced with the 6 & 8 speed transmissions. Trying to understand if this issue has been resolved with the 10 speed. Last question is more specific to the new platform in general, miles not specific but the more the better. Are the new trucks still experiencing the hwy speed vibration issues that a good amount of people experienced on the 2014-2018 models. I didnt particularly notice it on my 2014 AT but I did some on my 2016. Last I heard is GM was saying it was due to an extremely stiff frame and road harmonics so there really was no fix. Thanks all for your help, Murph
  5. Glad to hear I was able to point you in the correct direction. Unfortunately I have been procrastinating since the temporary fix I have made reduced the rattle by 80-90% so I didnt notice it much and if the radio is on I do not hear it at all. I have a quick question, how difficult was it to remove the trim on the door that covers the window switches? Since you have already removed then reinstalled the piece are there any areas where one would need to be really careful as to not crack any clips? Thanks gone_fishing. Murph
  6. I hope it does, I am just chicken to go and start disassembling my interior . After two days of simply inserting a folded raffle ticket in the door panel I still am getting some rattle but only on the worse section of road I drive that would cause a rattle. I have noticed though that the rattle had been reduce by 50% or more in sound volume and the stretches of road traveled that would cause the rattle sound had been eliminated by more than 50%. So I believe I am on the right track, maybe a thinker piece of paper (or folded more times) and put in more spots along the plastic trim might sure up the play reducing or eliminating rattle completely. I will continue to experiment with the paper and provide updates. Each persons rattle if coming from the same spot as mine will vary in severity so a single piece of paper might work for some and multiple pieces along the plastic might be needed for others.
  7. When you do disassemble them would you be able to do a DIY with pictures so we could give it a shot if the above fix does not work?
  8. So I just got done a short little test drive, went and drove over a bunch of road reflectors. The wedged folded raffle ticket seems to have fixed the rattle. I will give it a week to see how it holds and fairs over roads I know for sure would make it rattle. If this seems to be the culprit I would not doubt that it becomes a rattle many will experience. If this does fix the issue now I will just have to find something black that can give the same results, any suggestions?
  9. I believe I might have found the source of the rattle. There appears to be just enough play (very very minor play, so little one would say it is normal) in the plastice trim pieces where the windor and door lock buttons are. This play either allows for rattle under specific types of bumps with either the side trim piece "I have an AT tso that is the fake carbon fiber trim" or some other piece. What I did was take a raffle ticket I had which is a little thicker gauge paper and wedge it between the back side of that plastic trim and the door panel. I am about to go take the truck for a test drive to see if anything changed but just normal light bumps on the door panel makes me think it has worked. For those of you who have sent yours in and they cannot find the source try using the palm of your hand and lightly bang on the door panel around where the storage areas is. I did this and it allowed me to replicate the sound and pin point its location. Pictures coming shortly.
  10. Yeah I know the seat belt rattle, unfortunately this one is not that
  11. Just wanted to see if anyone has developed a rattle that sounds as if it is coming from the passenger side door. The rattle only happens on small but sharp bumps in the road like the small gaps between concrete sections. It also is very apparent on roads that are a little older where the smoother finish has worn down to expose more of the rocks in the concrete mix. It is extremely annoying specially on a truck that has under 3500 miles on it. Hoping someone has had the same noise and located the issue before bringing it in to the dealership. I also just recently noticed a feint clicking sound from time to time coming from my driver side door. I thought these trucks were supposed to have the quietest interiors? Guess they were able to keep external noise out but forgot to do something about their interiors falling apart after a few thousand miles.
  12. Adams leather interior cleaner and Adam's leather interior conditioner. Both can be used on plastic and rubber interior pieces. http://www.adamspolishes.com/c-18-interior-care.aspx I would get this exact kit that is on sale, use JULY4TH for an additional 15% off sale. http://www.adamspolishes.com/showproduct.aspx?ProductID=830&SEName=new-adams-leather-interior-care-kit DO NOT USE JUST CLEANER!
  13. Haha my salesman made a comment like "don't lose your key fob it is something like 300$ to replace".
