    Tips and tricks to have a nice ride.

    With no warranty I'd disable the AFM cylinder de-activation, get a tune module to improve the torque converter lockup, and do a trans. filter, fluid change, and put the revised trans cooling control valve as mentioned above. Should have a long term reliable machine with this.

    Main Bearing Failure with 6.2L at 3,200 miles

    I wonder if it's core shift due to heat cycles, water splash, stress. A 0.001 shift would wreck this modern engine pretty quick. Darn shame to do a heart transplant on a brand new machine like that though.

    Front bumper fascia lower molding removal

    Just about any of that type trim is a push on piece. Try prying at a corner and look behind it for a push in tab. If you see a gray adhesive strip it's 3M trim tape and that stuff is tough.

    Best place for instrument Cluster repair?

    Son's Silverado cluster started messing up,finally most of the gauges and readouts quit, most lights were out. Sent the cluster to a place called Circuit Board Medics in SC. Full rebuild and new lighting. $180 and 20 shipping both ways. That was last year, still working fine.

    Piston Rings

    I'd stick it in the bore and measure, If 15 thou or more I run with it. If under that I'd do more research.

    Ok to put 20" rims on 2024 Tahoe High Country that came with 22" rims

    Might want to match the outer tire diameter to the stock tires to keep the various computer systems happy. Smaller wheels with bigger tires would probably give a nicer ride too.

    Engine issues

    Might try some of these. GM created this for the early cars with aluminum heads on the cast iron blocks that were having coolant leads due to the expansion differences of the metals. I've read it was a factory install in the Cadillacs for a couple years.

    AFM / DOD Delete

    One of these springs lets go and it all gets bad real quick.

    Black Bear Performance Tune

    I kind of wish I hadn't gotten the extended warranty somewhat. I suspect that with some re-tuning the coming engine and trans. failures could be eliminated. I'm stuck with the AFM and slipping TC and trans.

    Do you ever sit in your vehicle to let the song finish?

    Back in the day I used to sit in my old Chevy when I got home and just listen to the engine idle. Duntov cam and glasspacks made for great music. Do miss those solid lifters and that cam overlap these days.

    2016 Yukon Denali weird stuff, sketchy gm dealer

    Could use a light bulb as a resistor to drain the system. Also like to use the bulb in series to power up the system gradually instead of the quick surge of a direct hookup.

    Why don’t my batteries last !!!!

    Walmart top battery in the big size for a Tahoe has a four year replacement warranty - when I last looked. Had good luck with their batteries overall.

    Lemon Law California. 360 camera keeps going black

    I'd have a sit down talk with an experienced lemon law atty. and get actual legal advice. Your case is probably one that hasn't been seen here. Vehicle going on 4 years old with some modifications and "unable to replicate" are some factors to consider.

    New Owner!

    Any service records with that machine? Might create a GM account and see what you can find out about reported service and repairs. It could be due for several things or, if well maintained, ready to go.

    Recommended warranty that covers emissions ?

    I'm thinking the GM warranties are handled by private companies but still backed by GM? But first read your actual warranty to see the coverage particulars. Could be surprised at the factory coverage.

    Traded my Accord for a Tahoe! *fingers-crossed*

    I'd look for maintenance records, if none I'd change the trans filter and fluid, check brake pads, air and cabin filters. AFM disable would be a real good idea, getting some tuning done on the transmission and torque converter lockup would be good if you can get that in your area.

    73 Camaro

    Nice to fine a solid body and floors to start with, looking good so far. Might check in with the 2nd gen guys at www.nastyz28.com for some help if needed. Couple guys there really know their stuff.

    Drive line Phasing, Is it still a thing?

    The dirt would upset me a little bit too. I am also real picky about keeping it clean, when I get the dealer lube job (get lubed in a couple ways there) I leave a note on the steering wheel to not wash.

    Drive line Phasing, Is it still a thing?

    Don't see how anything could have changed with the drive shaft with the seal change unless the pinion nut wasn't tightened correctly.

    Transmission getting Hot

    Do the cooler lines on this year run to the radiator tank like the older models?

    FLEXPLATE ISSUES…

    At this point I'd suspect something else making the noise.

    Indicative of bad alternator?

    That gauge reading along with the dead battery is a real good indication that the charging system is not up to par. Under warranty? Let us know what the dealer does for this.
