My 2014 continues to get stuck in 4wd, I have taken it to multiple dealers replaced switch and other parts. If I remove the 30 amp fuse it comes out of 4wd and you can hear the actuator move in and out when putting it in or pulling out. Never use the auto setting, it must be a programming issue that the dealers around me do not now how to fix.

Dealers replaced the switch and what else?. If you remove the plug from the back of the switch can you still hear the actuator?

Welcome to the site.

 

There was a reflash for the 14 and 15's due to the fact they would stay in 4WD if you turned off the engine while it was engaged in cold weather.

It happens even in the summer, and without shutting truck off. I would put it into 4wd drive for a few minutes and try to turn it off and it stays.

i remmember back in my 90's suburban the manual suggested to reverse the vehicle for 20 feet  after disabling the 4x4. iknow its a different system but maybe doing this take the loading off the shifter mechagnism so it can shift to 2wd

My 2017 (when the switch is on 2 wheel drive) when I am leaving my driveway going slow and turning I can feel the other tires pulling as if the 4 wheel drive is engaged. It also makes a whining noise. This happened 3 times one day. I turned the truck off and restarted it then it went away, but did it again the next day.  It is now sitting at the dealership and they cannot get it to replicate my issue. Anyone have an idea of what it is?

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Indeed a proper drain tap or drain valve with adapter that has a hose on it that opens up the valve as the adapter goes on is a slick setup and have that for certain highway tractors etc and other equipment that came from the factory with a tap but this L8T is pretty darned good other than me doing it on the floor and easy to touch hot exhaust and am not as agile as I used to be !. If I really want to pull a hot filter on an engine I will use an insulated set of thick neoprene gauntlet gloves but I am not in the hurry I used to need to be so things are done more relaxed and in theory somewhat safer ... I think LOL.    And as I mentioned the unique shape of the Amsoil 1 quart containers, while they might not work as well as an offset pour spout container for some awkward engine location applications, they are working a lot better with my Lisle funnel kit because of how they prop up on all four corners when upside down resting on the rim of the funnel where the typical quart container would never stay put without holding onto it.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      Well, I just hit 100K a few weeks back, and I can honestly say I have not had any major issues with my '21 5.3 Crew cab.  I have done most routine maintenance, oil changes, air filter, tire rotations, and a transmission drain and filter change (not even a full flush).  A couple of months ago, I started experiencing the dreaded CLUNK when coming to a stop, sometimes hard enough to literally push the truck forward! After researching here and in other forums/youtube videos, etc, I was thinking it's the slip yoke. I finally had a chance to take it to my local mechanic today, and he was not able to recreate the issue.  Amazing, since it does it nearly every time I drive.  He also said he can't simply grease my slip yoke/driveshaft splines, because I have a 1 piece driveshaft.  I am not sure what else I can do.  Has anyone else had this issue or have any idea what else it could be?

      This is where the Fumoto drain valve comes in handy.  No mess and able to change oil hot, like right off the interstate hot.  Flows nice and you can direct it into a container. As for the oil filter, I use an old dixie cup or plastic one from McDonalds. It contains the oil as you pull the filter down and not all over your hand.

      Which 2027 engine will you choose?

      By Black02Silverado · Posted

      Well, if it did change from lifters to rocker arms, at least it would be easier to fix as they fail.

      HighMileage oils or stay with Dexos 1 ?

      Doesn't hurt to try.  It's my understanding that you have to run it at least 4 or 5 oil changes for things to get clean.  Think about it, your engine didn't get dirty in just an oil change so over time it will slowly clean. It's the safest way to do it and not have seal issues.      I remember  a product that came out a long time ago, AutoRX, it was an additive you put in the oil and then drove for 3k miles. Some saw improvements and some didn't. It was suggested to use a non synthetic with it at the time. Same observation, use a couple oil changes and give it time to work. It also stated it worked best if you could drive on trips to keep the oil hot.  I'm sure if you ask AI it could tell you all about it.
