Hey guys I am new here, and just asking some questions that concerned me. I was wondering if it is good or bad to switch from 2wd into auto 4x4 or 4x4 high while driving? I know that 4x4 low should be switched while the truck is stopped, so I am just wondering if it will hurt anything switching while driving.

No harm in doing it at any speed. Like Stevens07, I feel better about doing it at lower speeds. Below 30mph in my case. If the conditions are such that I can be driving faster than 30mph, then the Auto 4x4 suits my needs better anyway. Just my .02. :P

I agree, I'll run auto 4x4 when on the highway traveling.

Hey Guys,

 

Just to continue with the original poster's question; if you have a 4x4 truck but don't use the 4x4 option that often, should you turn on 4x4 every once in awhile just to keep/make sure that specific parts are in working order?

 

Just bought my first truck so I've never used 4x4 before. Not sure if this info is needed but its 2010 Sierra.

 

Thanks,

 

Zach

back in 2005 I had a 2002 Tahoe Z71 and was in 2 wd I got on a bridge and it was ICE I was 1/3 thru a 360 degree spin when I I quickly hit Auto 4wd and hit the gas, The truck straightened out and I was a bit shaken.

Im gonna say it either saved my life or a long hospital stay as I was headed to a big drop off on either side of the bridge, Either way Im sure the truck would have been totaled at 65 mph if I rolled it

The Auto 4x4 is pretty sweet! :cool:

 

This is my 2nd winter with it, but last winter I'd just leave it on (Auto) for most of the season. I only used 4Hi a few times. I used 4Lo once, but that was just for fun. :eek:

 

I don't think there are any adverse effects from running Auto for prolonged periods of time. :P

My jimmy has auto 4wd, havent had it in winter yet but i can tell you that in the wet it preforms great. Like at a stop light on a incline and i want to take off fast in 2wd i just spin forever, but auto 4wd it just hooks and gose. Looking forward to the first snow storm to test it out.

Absolutely use it...at least once a month throw it on. Makes it ultra easy with the auto 4x4.

There should be no reason to need 4WD at speeds above 35-40ish. As for AWD (Auto) mode thats safe to use at highway speeds. Just remember, 4WD/AWD is there to help you get going when you don't have traction, it will not help you out in anyway to stop quicker!

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
