    2017 Yukon Denali Shudder Problem

    I like that color and wheel combo. Mine is white tri-coat with the double spoke 22 inch wheels. They are nice rigs. I've (mostly my wife) has enjoyed ours for 120+k. Good power, good mpg, and nice creature comforts. I hope you have many miles of good use!

    2017 Yukon Denali Shudder Problem

    I have the exact same vehicle. I bought it with 41k and had the shudder at 43k. The fluid flush works magic. I now have 162k on it and it's been great. Make sure to keep the fluid changed every 40k. I usually change the filter every 80k. The fact that they offered to replace the TC is huge...

    2015 and 2016 Escalade w/ 6.2 engines blown

    That is super ****** luck for sure. I do stand with @Doubeleive in that someone may be interested in them as they are and be willing to do the work if your family doesn't see the value in fixing them. If that's the case, throw out a suggestion here for PM about it. I have a 2017 Denali with...

    Is my transmission talking to me?

    I'm going with a torque converter that is getting bad. If it has the original setup, it's probably got the thermostat foe the trans cooler lines that cooks the transmission and causes failures. @NickTransmissions

    Is my transmission talking to me?

    What year, model, engine, and trans (4, 6, or 8 speed)?

    will it fit?

    Yes it will fit. I think they are both 6 speeds. There is programming that will need to be done so the new one talks to your ECU

    OEM parts on Amazon?

    I've had mixed success with Amazon on OEM stuff. Luckily the one I felt was a knockoff was a MAP sensor which didn't work, so it wasn't a big deal. Other items I've ordered have been OEM, or a very good knock off appearance as such. But, I usually stick to ROCK AUTO or Valleyparts.com. GM...

    Parasitic Draw Question.

    It sounds like a back feed through the lighting circuit, or an issue with the multifunction switch. Have you tried disconnecting the head lights and see what happens over night?

    Silverado Y pipe on escalade?

    I think the 6.2L has a larger diameter pipe than the 5.3L. If it's the same part number, then you're good to go. Other than potential diameter differences, the mount up should be almost identical

    Wheels spin

    Not I. How many miles on the tires? What is the climate you are operating in? I'm wondering if the rubber compound has hardened with age and miles?

    What's the highest mileage AFM motor you've seen or own?

    Currently at about 162k on a 2017 6.2L. Had #4 pushrod get bent, but replaced the rod and it's still running on the OE lifters. Time will tell....

    2018 GMC Yukon XL - Heavy Rain issues

    This has nothing to add to the thread, but more of a PSA about driving with hazards on in the rain.........STOP doing that! Your running lights are just fine. The 4 way flashers are so h a r d o n the eyes and distracting for everyone following you in the dreary rain spray that gets mixed...

    Towing with a rental Tahoe

    I can tell you from experience the rental company will say NO!!!!! Take that how you will. If your insurance guy knows the details and you have something in writing, then just go for it. It's about a 7 or 8 hour drive I'm guessing. Be sensible and you should be fine. I rented a tahoe in FL...

    What’s your cars name?

    Interesting. I've never dug into that yet. I'll have to see when I pull out the radio to replace the touch screen. But, given names are: 2017 Denali (white) - Surpise 2008 Denali (gold) - Goldilocks

    IS AFM DISABLEMENT NECESSARY??

    Is it currently stock? If so, then any computer changes would make it run in V8 all the time.......much like most everyone here agrees with. They system you speak of is prone to issues with the lifters that fail on the V4 mode. Dirty oil seems to be the biggest culprit for failure. Keep it at...

    2008 Yukon Denali vey rough misfire out of nowhere

    I don't believe they have an ethanol sensor. From what I've seen with HP Tuners on my 2008 in the fuel tables, there's nothing there as far as measured content. I think it's all based off the O2 feedback. I don't recall any modifier tables, etc for ethanol on the 2007 and 2008 with the 6.2L...

    2008 Yukon Denali vey rough misfire out of nowhere

    85 octane is also an issue. These motors can run fine on 87, but definitely like premium or better due to the compression ratio. If you have E85 available, you can make a blend of 25 to 30 percent of total capacity (I go by the fuel used counter on the DIC), and that will give you 93-97 octane...

    Possible front diff failure?

    I've noticed that on these vehicles, but not to that extent. I have a 2008 Denali, and I've noticed the slop in the front connection, but I service the front diff religiously since I've owned it. I do get a similar clunk sometimes on a downshift, and I've seen that same thing on other model...

    Main Bearing Failure with 6.2L at 3,200 miles

    They are using 0w-16 I believe on some new Chrysler vehicles per a service advisor I know. Yikes!

    2007 denali oil pressure questions. *video posted*

    I wouldn't sweat it. Those motors also have 8 o-rings under the valley cover that get hard and start allowing oil pressure to bleed off. Super easy fix. While you do that, put in a new GM oil pressure sender. Valley cover o-rings (or stand pipe/afm oil ports that aren't used on your engine)...

    Dreaded Effing lifter tap...... - SOLVED

    Well, update as of 10/19. Got the truck back and it runs as good as new. In going over the situation with my dad (master mechanic) he basically said it was most likely cause by a heavy right foot. In thinking back on the situation, my foot was heavy immediately after the situation, getting...

    Wow great mpg

    I'm assuming a diesel? Or, if it's a gas motor, how many egg shells did you put under your right foot and try not to break? LOL I would be happy for those numbers. Pretty impressive for a 6k vehicle

    Dreaded Effing lifter tap...... - SOLVED

    Yep, that is definitely a cousin to the Mazda CX-50. The Mazda 6 shares the same platform as the Ford Fusion which have been proven by multiple members of my family to be extremely reliable. Nice looking rig you got! And 40 mpg is pretty stellar. I did have a Toyota Sienna hybrid van as a...
