My 2019 Silverado Custom with 5.3 I have noticed it vibrates slightly, not really a shudder only when slowing down, its not a rotor issue or brake problem I don't think, it seems to have some driveline involvement, almost like they have built in some engine braking, Normal?

My truck does something similar and it is indeed shifting down through the gears as you coast.

 

I have the 6.2 so the shifting is probably more pronounced.

My 6.2L with 10 speed does the same.  slowing from 55 there will be a gear vibration I can only feel int the brake pedal then it goes away and has a good vibration before shifting into 1st gear (you will feel and hear the rattle) with a push.  Depends on the stop though.  real slow stop I barely feel it.  Firmer stop its more pronounced and will sometime give a pretty good push/kick after the vibration as it shifts into 1st.  Had 4 people at the dealer drive it and all said they couldn't feel it.  I still feel it every stop.  I have a 2015 Yukon XL with 6.2L and the trans sucks on it but I do not feel anything when slowing to a stop.  I have tried driving in sport, and tow mode. no change. Tried all with out traction control as well.  I keep thinking it will go away.  its not getting worse but not getting better either. I do have a 6in lift with 35s but I am sure it did the same when it was stock, it was just harder to feel.  Just rolled 8k miles.  6k with lift.

Mine is doing the same thing except I have a 2019 8 speed with the new fluid. From 23mph down, until it shifts into first if feels like a rumble strip. I thought the 10 speeds were safe from this but I guess not. Guessing it’s the torque converter locking up?

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      frustrating P0446 code

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
