    What does your MPG look like?

    For starters I have a 2006 GMC Yukon denali XL, with a 6.0 LQ4 and it just went passed 216k miles. Normally I drive it like a 6 liter V8 should be driven haha but with everything going on I’ve been taking it easy cause money is a little tight lately. Anyways, I used to get around 12 mpg now I’m...

    Did I cook my Trans?

    I’ll start off by saying I have a 2006 GMC Yukon denali XL, 6.0L LQ4, with a 4L60e trans. Yesterday I upgraded my stocktrans cooler to a Trucool performance trans cooler, all went well and I thought I was set to drive it the next day for an event. Anyways, earlier my husband and I were driving...

    2015+ Escalade taillight on a 2006 Yukon Denali XL

    How long have you been building the truck? I got mine in December of last year, and since im in school, its been slow and steady in modifying and replacing parts. Also whats the most difficult thing you've had to fix/replace on your Denali? For me I had to replace the entire cooling system lol.

    2015+ Escalade taillight on a 2006 Yukon Denali XL

    Adventurenali92, i was literally looking at your build thread before i got the reply update on my thread lol, but yeah im not sure if it would look the greatest, and there are way better looking aftermarket lights that specifically. I just thought I'd entertain the thought a little and see...

    2015+ Escalade taillight on a 2006 Yukon Denali XL

    For starters, I have a 2006 GMC Yukon denali XL, stock LQ4 6.0L engine, body is stock as well. my question is, can you put the stock 2015+ Cadillac Escalade lights onto my 2006 Yukon denali XL? Also, yes I know that they won’t fit normally, they’re not the same size. However, if they’re was...

    Vibrations at idle

    I guess I should have said that originally, my bad. The Plugs are brand new NGK, and the ignition wires were replaced as well, Duralast gold. I haven’t done anything with the fuel filter, I haven’t noticed any problems with it as of yet. The odometer is just why if 211k, and as for the vacuum...

    Vibrations at idle

    06’ Yukon Denali XL, 6.0L, AWD I’m just curious if anyone knows why it does this, or if anyone else experiences this. I don’t think it’s a very serious issue, and it could very well be the rubber engine mounts are on their way out. It just vibrates or like shutters I would say at idle. It’s not...

    Spark Plug Removal Issues

    Sorry about that, when I wrote this I was just in a hurry and a little angry cause of the spark plug situation, so I didn’t think to put my trucks info down. It’s an 06’ Yukon denali XL, 6.0 engine. I think that’s all I need to put, but it’s just a massive pain to take these things out, I...

    Power steering has left the building

    The PS reservoir drains pretty fast, I’ve narrowed it down to the high pressure line, return line, and the cooler/ cooler line, but I’m not too sure. And to add to that, I’m not sure if I have hydro boost or not, let alone where it is if I do.

    Power steering has left the building

    So I sound dumb I know, but I’m leaking power steering fluid, and im going to fix it in the near future, but the only part that I find confusing is the hydro boost. Do I have it? How do I know if I have it? Where is it? Any links for more information on it? thanks

    Denali exterior door molding

    My 2006 GMC Yukon denali came with the door molding off on the driver door, I don’t know how to put it back on, and there isn’t anything online that I can find. Anyone know how to put it on, or a link someone can provide. Thanks

    4L65E Trans Is A Grenade Change My Mind

    Cash ain’t the problem , I got I respect that, and completely understand, but that ain’t in my personality. It ain’t the first Yukon I’ve had and won’t be the last, and plus I like the challenge. I’d rather go out and have something to chase rather than stay stagnant and settle for what I...

    4L65E Trans Is A Grenade Change My Mind

    They’re super strong transmissions, but the next Denali I get I’ll be putting a race/ heavy duty transmission in it.

    4L65E Trans Is A Grenade Change My Mind

    Well it did have a few other issues like a/c just was done. And me being 18, I don’t exactly have money to get a 700+ rebuild or a 2000 new transmission. It’s not like I went without a fight, just not much I could do. But I’ll be getting a new one in a couple months. I still got the fastest Kia...

    Paint colors

    What kind of paint jobs do you guys have on your builds? Trying to figure out what kinda color I want on my next denali. I was thinking some blue variant, because while black looks dope af, it’s overused in my opinion.

    4L65E Trans Is A Grenade Change My Mind

    That’s what I was thinking, but that was super expensive, and I called a few places but there aren’t many around here. But it don’t matter now, it’s already sold and I’m just biding my time to save up for another one.

    Ideas Or Awarenesses

    That’s a dope build, is he going for a race build? I mean I’m sure I could get this thing to go real fast, but I’m more about looks ykno. One thing I’m really trying to figure out is if the new Escalade tail lights can fit into this, says they can’t, but I’m sure I can find a way!
