I know this thread is a little old, but for what its worth, I just bought a 2026 3500 LT / Z71 Trail Boss (man, how many labels can they put on a truck) and it does the same thing.  It is especially noticeable when going through traffic circles, and you can hear it a little bit when sitting at a stand still.

 

A little annoying especially coming from a 2024 Colorado ZR2.  That thing was deathly quiet in every respect.  

Great truck by the way.  I just needed more functionality for the very long term.

Your Colorado had car like electric power steering the HD trucks use hydraulic reticulating ball steering, which is from like the 60’s. They are not silent. Just drive your truck. They are built to work. When ppl buy them thinking they are Cadillacs they nit pic every little sound.

Thanks for the info.  Is it normal during the first few hundred miles (or however many) for the transmission to have some occasional  hard / rough 2-1 downshifts (like coming to a stop at a red light)?

Yes it is. My 6L90 did it 2 or 3 times mainly when coasting down to a very slow speed in a parking lot but never does it anymore. It’s a learning thing. The transmission has to learn your driving habits.

Haven't had a single hard downshift in my 2026 2500HD LTZ TB. It's been pretty smooth. The only thing mine does is have a whine around 3rd and 4th gear up to about 38mph. This is supposedly normal operation too.

The hard downshift seems to occur when you are coasting approaching a stop in 2nd, and then give it a little gas for some reason, such as a slight incline up to a red light or you just want to add a little speed before subsequently stopping. As others have said, the computer seems to learn that you are not suddenly asking for max torque when this happens, and it softens the 1st gear clutch application. My 6L90 did it several times when it was new, but stopped within weeks. I have an intersection leaving my neighborhood that was just the uphill situation I described above, and it shifts smoothly on the approach now. The shift is still fairly firm, like it’s not messing around, but not clunky.

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.
