I have a 2020 gmc sierra sle 5.3 and the ten speed and I find second gear a little slow to engage compared to all other gears. Anyone else find that. It seems fine though if I hit the throttle a little harder than normal. I don't have a heavy foot lol

I have the 3.0L Duramax and the ten speed.  Same thing happens to me 99% of the time.  All other gear changes are of the smoothest and fastest engagement though.  

 

Not sure why the 1st -> 2nd change (accelerating) is like that.

If you mean it stay in first longer than seems normal, I agree. But it only seems to do it (for me anyway) when I’m accelerating down an incline. Otherwise, it’s buttery smooth. I’m on my second 6.2/10 speed T1 and they both acted the same.

Not that it stays in first longer, but the first to second change is often much, much more noticeable than any other change.  In some cases, it is harsh.

 

Now, I've only got 700 miles on mine as I recently bought it new so maybe that has something to do with it.  

 

Maybe something to do with the trans fluid not being warmed up.  Not sure, I'm going to pay more attention and have the dealer share their thoughts on it.

ive got about 20k on mine and its still noticeable. I noticed it day one but also thought it would work its way away. Will have the dealer look into it when I take it for an oil change.

I get it too. 2020 trail boss 5 3 10 speed. 1-2 seems to hesitate or almost slip a little before engagement to 2nd. Mostly noticeable under very light acceleration worse when going up hill. Nothing I'm going to worry about. It's still light years ahead of the 8 speed clunker I had on my last truck.

Not terribly worried. Just sucks because every other gear change is smooth as silk

      Breaking News!    I'm going to tell you that I'm going to tell you.  Then I'm going to tell you what I'm going to tell you.  Then I'm going to tell you.  Then I'm going to tell you what I told  you.  Then I'm going to tell you what I'm about to tell you on the other side of the break.  Then we're going to break. Then I'm not going to tell you what I told you I was going to tell you.  But I'll tell you something else that is Breaking News just coming to the desk that everyone reported on yesterday.  Then I'll tease a human interest telling I'll get to on the other side of a larger break. Then I'll tell you one item in 20 seconds and go back to an even longer break. Longest break of the night.  Then I'll tell you a fluff piece that takes 10 seconds and sign off into a three minute break while you wait for the next 30 minutes of rinse and repeat on the local news.    In al you'll get about 12 minutes of something, 5 minutes of which is worth hearing in a 30 minute show and 18 minutes of advertising at a sound level twice as loud as the news.    Of course you can switch to cable news and hear 12 different people tell the same four stories in much the same format as the Network News for 20 hours of which the majority will be advertising.  And four hours of late night Specials about things you wonder why you stayed up to listen to. Half of which will be repeats.....   OR you can go for a drive

      Audio Dampening and quiet

      By Afennell19 · Posted

      Did you ever figure this out? My 2022 Trail Boss, and now my 2026 LT did this from time to time.  I believe it was more connected to Android Auto and my phone being the cause. Maybe try going for a drive, sans cell phone.... and see if it happens?

      2026 Sierra 1500 Denali - Sound upgrade?

      By Afennell19 · Posted

      I have a 2026 Silverado LT, the non bose as well.  Upgrading the door speakers is pretty straightforward. You could honestly go to walmart, or Auto Zone/ O Reilly and get a set of 6x9s for the front, and 6.5s for the rear. You do also have to get some adapters for each, but they are like $10 a pair on Amazon. Then some plug and play harnesses that are about $10 a pair on Amazon as well.  And I would also suggest a 10 pack of the Amazon Basics sound deadening. Slap that all around the speakers and on the open metal of the inside of the door. And your golden.   I am currently doing this with my Silverado. Although I am having a bit of trouble because I am snooby I guess and bought some Alpine S2 S69c's which are 2 way components and I am having to wire from the door up to the dash....  Having never installed speakers before, its taking me just a bit to get everything correct. But if you dont buy expensive component speakers, and just some $40-$50 door speakers. You will DRASTICALLY improve the sound over these stock paper cone junk speakers. I thought my Silverado had an issue with the radio/ sound for a while.  Come to find out.  The stock speakers are just THAT SH*TTY   I cannot wait to have some decent sound in the truck   What did you end up doing?

      Parking Brake - Automatic Engagement Questions

      By newdude · Posted

      Its all automatic based on yaw sensor data.  If enough incline is detected, it engages.   My recommendation though would be to disengage it before driving off and not let it auto disengage by touching the gas pedal.  The HD trucks use the same setup as prior years, the drum in hat park brake.  But now with an electric actuator.  If you drive off repeatedly over time, it can torque the park brake shoes and can also prematurely wear them out.           Electric console shift will set the park brake on flat ground too.  Pretty sure they've got it programmed to activate every time.
