    Rancho QuickLift

    Reviving this is super old thread — @Solace how have your ranchos held up? I’m considering replacing my stock z71 suspension with Ranchos..

    Z71 Adventure Wagon

    I took the burb up to Summit County, CO this weekend - it was my first time driving it “hard” since it bought it. My recent transmission work and tune worked really well. The engine kept pulling well past 70mph on some mountain grades, and the highest temp I saw for the transmission fluid was...

    Overland Rebuild of 2015 Yukon XL w/200k Miles and a blown tranny @ $9500

    Sounds like a great build already! Do you mind telling us how much you spent on the drivetrain upgrades? I’d love to do some similar upgrades if/when things break at higher mileage.

    Need some suggestions on all terrain tires

    I live near denver, and recently installed some Nokian Outpost nAT’s on my suburban. They’re quiet, they’re nokians (3 peak symbol, winter-biased compound), and they’re reinforced with aramid fibers similar to Kevlar. Mine are E load rating because I plan to off road in some remote places, and I...

    2011 Yukon XL LT - Overland Build - Input Appreciated

    I just bought a 2019 z71 - I have a 3.42 rear axle and just went up in tire size to 275/70/18 (33s). I agree with what was said here - I wouldn’t go much bigger than 33 without regearing. I just tuned mine with a canned superchips tune, and it really livened things up. It also allowed me to...

    Just wanna say…

    Happy Holidays! I'm very thankful for TYF! I saw this holiday commercial by Chevy yesterday

    Headlight Trim

    I know this thread is old, but I have the exact same need/question as you. I want that little “eyebrow” on the top of my headlights to be black. Did you find a solution?

    Thanks! The z71 was in its element

    Z71 Adventure Wagon

    Next up is the tune! I thought it would be a bit farther out, but I found a great deal on a superchips flashpaq f5, and snagged it. I installed the 87 octane tune for now, and included some options: -afm/dod disable -increased idle by 50rpm at idle in park and drive -increased my tire size...

    Z71 Adventure Wagon

    Had an eventful Friday/Saturday around here, and got two big ticket items done. I’ll split them into two posts though. The first is my transmission service. The pan gasket and filter came in on Friday, so I spent a few hours getting the transmission all taken care of. It shouldn’t take a few...

    Z71 Adventure Wagon

    @Joseph Garcia helped me out in my intro thread, and I confirmed that I do NOT have electronic or air suspension. These RPO codes would be present if I did: Z55 - Electronic Suspension Z95 - Magnaride Suspension Also a good thing to note is that starting in 2018 GM started replacing RPO code...

    Z71 from CO!

    Thanks! It looks like I do NOT have electronic suspension, so I'll add this info to my build thread: https://www.tahoeyukonforum.com/threads/z71-adventure-wagon.145410/#post-1835618

    MILEAGE POLL

    They were on it when I bought the burb. I believe they’re aftermarket though. I haven’t towed with them yet, but I can confirm that they provide tons of visibility behind you. Biggest mirrors I’ve ever had haha

    MILEAGE POLL

    I can’t help but notice quite a few non 2015-2020 owners chiming in.*** Just picked mine up at 88k miles. I plan to keep it running as long as possible - right now I’m saving up a bit for a tune, intake, exhaust, and a lift.

    Z71 from CO!

    Thank you! I agree - such a beaut!

    Z71 Adventure Wagon

    No I’ve got the 6L80 6-speed. I extracted the fluid via the transmission dip stick/fill tube - it was a super easy process. Then I measured what I took out, and filled it back up with the same amount and checked the level after a drive. I’m also going to do another drain and fill when I drop...

    Z71 Adventure Wagon

    I hear ya- I really like the visibility! I believe they are a pretty easy swap, but mine were already installed when I bought it, so I’m not sure. One thing to note though is that you might lose the power folding functionality. Mine do not power fold even though I have the button.

    Z71 Adventure Wagon

    I agree! I feel like once a few automakers started treating trans fluid as “lifetime” fluid, most drivers just started ignoring it.

    Z71 Adventure Wagon

    Had a nice warm day this weekend, so I did a quick drain and fill on my transmission. I used an oil extractor and it worked like a charm. No mess. I’m really glad I did, because my transmission oil is pretty worn, and I’m pretty sure it has never been changed. I only replaced 5qts for now, and...

    GM 6L80 Transmission Information Thread

    Thanks! Good to know that it has two coolers - I would have assumed it just had one.

    Z71 Adventure Wagon

    Thanks! I thought they were too big at first, but I’m enjoying all of the visibility they provide. I totally agree - I liked those flares too. I will say though that I like the sleek newer body style of the 2015-2020 gen, and the black accentuates it.

    GM 6L80 Transmission Information Thread

    Hi @NickTransmissions - great info on this thread - thanks for starting it! I just bought a 2019 Suburban with a 6L80, and I’m gathering info to do my first diy transmission service on it. I have a question regarding the 6L80: Where is the transmission cooler located? I figured it would be in...

    Z71 Adventure Wagon

    I had a warm afternoon and a spare hour, so I swapped in the new transmission thermostat bypass. I wanted to get it done before I service the transmission because I’ll be doing some mountain driving soon, and don’t want to strain the old transmission fluid any more than I have to. The swap was...

    Z71 Adventure Wagon

    I got the new tires installed yesterday, and they’re great! I think 275/70/18 is a great size on the stock suspension, and I really like the .8” lift they provide. I’ll report back once I get more miles on them, but so far so good! Next up is som transmission maintenance..

    Z71 Adventure Wagon

    Thanks! Ah you're right haha - they're by far the biggest mirrors I've ever had. I may switch them out for smaller ones, but I do like the visibility the provide on such a huge vehicle.
