Me too. Exact same thing. Thank you Cmillerjr for staying on top of this and checking in with your dealer as to when a fix is available.

any news on this? There is a way in the infotainment system to check for updates. I was curious if this would be an update so we didn’t even have to go to the dealer.

Bedcover came in! Solid Fold 2.0 - and the auto down tailgate still works!

I have the same problem with the camera. Has happened a few times. I think the camera uses a software to change the bubble to a surround type view. And sometimes it doesn't kick in correctly. I am thinking a software update will fix it pretty easily.

In general are the 2018s better? Or same stuff just different year?

I didn’t push it too hard, but I definitely had fun.

No I wish I could. Car has 900 miles in that pic ?

Picture of using my 1LE.. congrats on yours!

Actual clunk noise. Audible over the radio.

Apparently so! Since I have had a 2016 and 2017 GMC Sierra SLT with the 6 speeds, I have come to a few interesting conclusions. All 6 speed (even though the same truck in an assembly line) are not created equal. My 2016 had a clunk downshifting but it was never as pronounced as my 2017. However, my 2016 had a weird shift from 2nd to third and my 2017 never has that issue. I always feel the v4 /v8 transition in both trucks though

I acknowledged that there are good working trucks in my post, you clearly chose to remove them from your response. Please see yourself out of my thread.

Thanks for the advice. Will give it a shot.

I had a 2016 with the 6 speed with similar, but somehow different behavior that I changed the trans fluid at 5000 miles to the same factory fluid. I had no change in the activity of the transmission. I was specifically asking about a change to a different brand or full synthetic etc.

Always love the "mine is perfect... blah blah blah..." It is great that you have a "perfect" one, or more likely just don't notice it because you listen to the radio or are deaf, or just aren't in tune with what your vehicle is doing. I have ridden in great trucks, but I have also ridden in service loaners that are brand new trucks similar to mine that also exhibit the same behaviors mine does. Was curious if there was any new news on the 6 speeds, seems like the 8 speeds have gotten all the attention. Chiming in with the "mine is perfect" crap doesn't help. To be more specific, I get a clunky, audible downshift from 3->2 and 2->1 at least once every time I drive my vehicle. It doesn't happen often when it is cold, usually when the temp of the trans is 120 degrees and above. As the transmission temp increases, the viscosity of the transmission fluid will change which lead me to hypothesize if changing the transmission fluid to a different type might help, because my truck never clunks right when I start it and get up to below 120 degrees

lol. yea trading out to a different truck would probably fix the problem. Was hoping to find something more pocket book friendly until the 2019s arrive with the 10 speeds. The 10 speeds I have test driven have been wonderful in the 2018 yukon denali and escalades. I have had mine in the dealer and have the latest software also.. and reproduced the clunk and got the "its normal" talk.

Tune from Blackbear didn’t help me, just changed when and how the downshift clunk happened.

Has anybody with clunky downshifting on their 6 speeds switched out their transmission fluid to another’s brand/type of fluid other than factory with any help with the downshift clunk?

I swapped the charging module out in my 2017 Sierra -- I also had to swap out the connector... it is kind of difficult, you have to be careful. Thread here.... read up and order the parts. My iphone x charges perfectly now.

I swapped out the charging module and connector in my 2017 sierra -- now my iphone x charges perfectly. Kind of an involved process, have to be careful with the connector. But it works perfectly.

Thanks, I had a 2013 ZL1 before this. Funny thing is this car feels just as fast. 750HP would be insane.

Thanks. I like the blue too. And the gray.

My 2018 Camaro SS 1LE next to my Sierra.

I found it somewhere.. I can't seem to find it now... if I remember correctly it has to do with the difference in wattage output in 2017 and lower model year vehicles; the iphone x requires a higher input wattage to start and maintain the charging process. After you go through all the trouble, you will get the iphone x to connect for a few seconds and then disconnect and it won't continue charging. Best of luck, though. If you get different results please report back!

Here you go -- don't waste your time... https://support.apple.com/en-us/HT208148 That is why we have been asking if we can get updated chargers or console lids from the 2018 model trucks.

It won't work -- the 2018s have an updated charger that works with the new iphones
