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.

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.

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.

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
