    22 yukon xl Torque converter issues

    I would ask "why is it bad" or "what evidence supports this claim?" How has it been driving/acting? Have you ever had the transmission serviced? If not, maybe a fluid and filter change may make a difference before jumping on the repair wagon. On the other hand, if its slipping, jerking...

    Oil recommendation after DOD delete

    Just run 5w-30 full synthetic like the non-AFM (DFM) 6.6L truck motors run. It's the best middle ground for everyday use. You don't have the problematic lifters or system anymore, so lube it with a real oil that will do the job correctly. I've run it on my 2017 6.2L for almost 140k (178k on...

    Anyone here off-road their Yukon?

    Here's my setup for a trip to the Alpine Loop in CO. My brother and I will be home soon from a 5 day trip out there. I'm currently snug as a bug typing this out from the sleeping area of the Yukon while he drives for a shift. I remove both rear seats and make a platform from 3/4 inch plywood...

    NHOU Undercoating

    This ^^^^^^^ is the way. Very effective solution that is cost effective. I do a similar program here in WI. @Aquamania001 As for the dripping all over the driveway, that hasn't been an issue. Fluid film, or woolwax, is thick and sticky. I've rarely had anything drip off, but it does happen...

    6l80 tcc slip tuning stock clutch

    @Marky Dissod did you change parameters in the torque management section as well? I haven't delved into that yet, but have made conservative changes on my 2008 Denali, 6 speed. 1. Lessened TCC slip by about half across the normal range. I compared a file from a 2015 HD truck with the 6L90 as...

    Electrical/Charging Issue

    The belt is always spinning, its a standard alternator, no decoupling takes place. If that were the case, there would be an electro-mechanical clutch (like A/C compressor) to activate, deactivate, which it does not have. The voltage output is controlled via the field excitation commanded to...

    Screen issues

    Its just a bunch of trim pieces that need to be removed to get the radio out. After that, it's finite work with small electronic tools (think cell phone screen replacement set of non-conductive type picks, etc). These are also on Amazon for a few bucks. There's some good videos on YouTube. I...

    Adding extra reverse lights

    If you have your LED lights, maybe try using the 12v power for the reverse pin on the trailer brake connection and the ground. Have someone put it in reverse (needs to be running I think) and see if it senses the electrical load. Maybe it will work at that point and you can figure out how to...

    Screen issues

    Its the LCD screen going bad. It happened twice on my 2017. 1st was warranty and that failed again after 2 years. 2nd time I just bought the screen assembly off Amazon and replaced it myself. Parts were about $200. It's a bit of a pickle to do, but if you're mechanically inclined with some...

    Still using E15 in today’s trucks?

    I've run a blend of up to 40% in my DI 6.2L and it doesn't seem to phase it. It actually liked the 20% blend rate, got decent mpg, and still had good power. I've also run a 20-30% blend in my non-flex 2008 6.2L and it also likes it. I find that if I drive like its 87 octane, then the fuel...

    High Mileage tahoes/yukons/suburbans

    You have purchased about 25,382 gallons of fuel to achieve that! Assuming a 17 mpg average. Holy crap there road warrior! Well done!

    Small Wheel / Large Tire on a Suburban?

    The 2024 and newer colorado use the same bolt pattern as the 1/2 tons. The wheels are interchangeable up to 2020 on the SUVs, not sure about 2021 and newer tho

    How do we feel about a "Fuel induction service" on the recalled engines?

    I have 177K on a DI 6.2L and have only once used Sea Foam DI cleaner. I don't see the value in it......especially from a stealership.....and that's ASSUMING they do it right. You'll be fine, just keep the oil and filters clean and move on with life.

    Driver brake drag

    Since you did all that with the same results, I'm speculating ABS unit. Do you have the ability to run a bleed cycle on it with a scan tool? Or a gravel road you can do some ABS stops on? You may have a piece of crud floating around by a check valve, etc that needs to get moved on down the line.

    Driver brake drag

    Have you checked the rear hose for that caliper? They can check valve themselves with age/damage and hold pressure on the caliper. Bleeding them makes it normal again. Using a line clamp, you could block that wheel off and see how it acts. My guess is there would be no binding. It's either...

    What are the risks of letting AFM self destruct?

    Based on your pictures I'm going to guess it was a Michigan truck, maybe Ohio. That level of rust is permanent, but if you want to learn body work you don't have much to lose LOL. After listening to your video, it kind of sounds like piston slap, hard to tell for sure without being there...

    What are the risks of letting AFM self destruct?

    I'd save your money and just run it. With 208k and RUST starting to show, it's going to become a perpetual money vacuum. These trucks are pretty well built, but when rust does show up, it's been working at awhile and will not stop at that point. I've been a mechanic in the Midwest most of...

    Anyone swap 2015-2020 seats into their 07-14?

    There might be a way to get the newer seats from a 2017-2019 Buick lacrosse to work. Man, those are nice seats! Finally someone at GM pulled their head out of their pooper and really did a good job..........then they quit making the car. :banghead: :happy175:

    Replacing 4 year old Genuine GM Waterpump w/41K miles

    LOL! I SECOND THAT IDEA! Still running the original on both rigs (205k and 178k). I really like @KC 2013 Tahoe maintenance schedule. It's a bummer the OEM one let him down......it's usually not the case. I'd say try it again with a new OEM one. I've also had decent luck with Napa and...

    2018 Yukon Denali question

    You'll need access to a tire machine and balancer. Then use a tool to activate the new sensor when installed on the vehicle, or go through the relearn process for all 4 with the key fob/corner light/horn honk/ air pressure adjustment. Either way is easy. Get the OEM sensor for $60. The...

    Anyone swap 2015-2020 seats into their 07-14?

    100% agree with @PG01. My 2008 Denali seats are way better than my 2017 Denali IMO. The 2017 are better materials, but they forgot the correct amount of padding...... I would agree that cooled is a must. Look for the equivalent model year seats from an Escalade or Denali. Escalade had...

    Anyone here off-road their Yukon?

    This ^^^^^^ is the correct answer to CV axles breaking. Treat them normally and they will last the life of the truck. You can even drive spirited and they are fine. Treat them madly, in a blizzard, stuck in a ditch, with the go-pedal down hard and cutting the tires back and forth for...

    Anybody else less than enthusiastic about the direction Chevy is taking with the Tahoes and suburbans?

    I agree 100% with @Blueinterceptor. The newest stuff from 2021 on have not grown on me yet. I feel they are extremely overpriced, WAY too much gaudy tech, cost cutting up the wazoo which leads to less than desired issues/longevity. Unless the BS CAFE stuff that has been implemented actually...
