    Factory Look Aftermarket Head Unit/ Reciever

    Does your Advent have an aux. input? Couple RCA input jacks on the back side? Could add a BT module for under $20 and those do work really well.

    Transmission fluid - 6L80 17 Tahoe PPV

    My son had his 6l80 rebuild and tuned and the only difference I noticed on the transmission was by watching the tach. When the TC is locked it is solid. But in a deluxe heavy vehicle a firm shift might not really stand out?

    Main Bearing Failure with 6.2L at 3,200 miles

    And I used to run 15w40 Rotella with a can of STP on the old small blocks with a high volume pump. Never had a failure though.

    2017 radio presets gone weird on me?

    Might hit the Home button on the panel below and start over on selections. Won't change anything but the display.

    Warranty

    Your Tahoe is right at the point where bad things start to happen, and these aftermarket warranty outfits know it. As above, read the exclusions very carefully, if you can even get a quote.

    New Member - Tim **. - 2019 Suburban 6 speed transmission & sucks touch screen "info center"

    Our touch screen is ghosting too. I pulled the fuse, cleaned it really good, put some Pledge wax on it, then calibrated it. Helped it some. When it starts acting up I raise it (the compartment door) up, touch screen goes dead but the radio and manual controls all work and the DIC is not...

    Main Bearing Failure with 6.2L at 3,200 miles

    I don't like the idea of 0w20 oil either (slippery water) but with all the oil dependent tech in these motors what else can be used? But I suspect the failures on this series of motors is more due to block shift and casting materials.

    Windshield side weatherstipping/trim, does it tuck in?

    Might have a mess on your hands as that new windshield is really glued in.

    2024 Denali road noise

    Heavy vehicle with aggressive tread tires do make a lot of noise. I also like the Michelin tires.

    2021 Denali/Recommended maintenance

    Couple ways they might do this. Blast the intake valves with a wood type dust to clean the back sides of the valve head. Or shoot a cleaner liquid solvent through the intake to do the same thing. Pretty early for this and I'm not real sure that is good for the modern styled piston rings and...

    GM Reman 6L80 Transmission - new TBV?

    Son had a rebuild put in his 2017 a couple months ago. Independent shop local that has been in business a long time and know what they're doing. They "flipped the pill" and did a retune on the transmission and eliminated the cylinder confusion deal. Sure drives different, I'd do that to ours...

    Help trying to figure out chirping noise

    Grandson has an 04 Silverado that makes a noise similar to this I think. Might be a similar system as yours. We found that we could move the heat control just a bit toward the warm setting and it would quiet down. Probably not your noise but easy to try it.

    Locked Up - Won't Move

    Drum and pads? If the rear brakes are drums and shoes take a look at the wheel brake cylinder on that wheel. Pull the rubber boot and look for white built up corrosion. Those will crust up and lock in place after applying the brakes sometimes.

    What year machine is that?

    Never seen this before - Parking Brake Shoe Replacement Help

    Might rotate the disc several times and see where the rub marks are on the little shoes. Maybe a little bit of material removal could free it up. Should have a really good EM brake when done I'd think.

    2011 Escalade - worth repairing?

    I like the idea of a back up car too. Something that gets 30 mpg and somewhat reliable. See Malibu, Cruze, Fusion, lesser Japanese makes in decent shape under 100k miles for $5k or less. Much less sometimes. Won't impress anyone but does the job.

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Those are 4 ohm speakers. Could be the extra load on the output would change the sound quaility some. I did get to a web site with the link, heck of a deal if true.

    Idea On Cost To Replace 5.3 Engine? 2015 Yukon XL

    Zero compression on one cylinder would have to indicate a valve issue - unless there's a big hole in the engine block. Get someone to pull the valve cover and find out what's going on.

    Arlington plant closed temporarily - Open Now

    And that JIT supply means there's no warehouses full of parts for replacements. Couple years down the road and you need an unusual part it's junkyard time. But I suspect non-union N. Carolina does supply a lot of the parts these days and Helene probably shut down a lot of that.

    2009 Tahoe Sell it? Fix it? or Parts it out?

    I'd list it for whatever price you can come up with, (no clue what it's worth) and see if there's any interest. Have it running even with the engine noise. It still looks decent and these older Chevys are somewhat in demand. Leave it sit in that declining condition and it will wind up having...

    Common black Tahoe

    The main thing that stands out on a black Tahoe is keeping it clean. Really clean. Your Tahoe is equipped perfect I think. Nothing looks better than a super clean detailed black machine.

    Glitter in the oil after the DOD delete?

    For that stuff to be circulating in the oil I'd hate to look at the crank bearings. Good that you changed that oil again. Cut the filter open and see what's in there too.
