I followed your instructions to a T, except the step; open passenger door. My hands are horribly injured. Please folks, don't reach through the door, open. It!
No not at all, my truck is not a z71, it's just a 2LT and I've seen it on fleet spec base model 2wd work trucks as well. I believe it was an independent option for almost any trim level
Oh definitely not believe me, she'll lock up in 4 lo 4 high and even 2 high as long as you've got the traction control off and spin the wheels a little, I've well tested that lol smokey burnout machine for sure. But as of right now my trucks got about 125k miles on it and the transmission was starting to worry me (hard shifting, feeling sluggish, running hotter than it used to etc) however alot of people were telling me/i read that it is very important on these trucks to change the trans fluid and filter, so I finally broke down and said what the heck I'll give it a shot, and since I changed the trans fluid and filter, I'm not kidding you when I tell you that the transmission feels better than the day I bought the truck off the lot (I got it used with 20k). Trans temps are normal now again, shifts are Cadillac level of buttery, and all the ol 5.3s power has definitely been restored. I dont know what it is but for some reason, doing a trans fluid and filter change on these trucks does 100% make a night and day difference on them, so, so far so good long story short
@@notasolution right on ! I just got a 15 silverado with 85 thousand miles, seems to shift pretty good for the most part but i should prlly have the drive train fluids change to be on the safe side
@@notasolution coming from a 5 speed manual I feel I have been listening to every little shift and noise that prlly is not even there lol becuase it seems to shift pretty darn smooth
@@Jake_Hynds no I didnt do a full flush, I just dropped the trans pan, let all the fluid drain out that came out of it just from dropping the pan, cleaned the pan out, changed the filter and put it back together and filled it back up.
I got mine off of craigslist back when craigslist was still the #1 way to find used stuff. The light pods are just off of amazon though. The bar was a pain to bolt on and wire up though, you have to take the factory tow hooks out in order to mount it and one of the bolts has to be cut if you dont want to take the whole front end of the truck off to have enough room to get it out. As long as you dont mind losing your tow hooks and cutting a bolt though, I think it's a great lil aesthetic mod. Took about 3 hours total I wanna say not too bad
A chevy dealer should be able to look up your options on a build sheet from Vin # I just found this out today he printed it out and I asked if I could keep it. Has a lot of info on it that I didn't know and would have no way of knowing without it. Because it's what the truck is instead of guessing from what other people have put out there. With so many different truck models
If it doesn't list the G80 code, more than likely you don't have it. However, you can contact the service department at a dealership and ask them for sure.
@@adam4g63 tried it alot for the last 4 months still never worked so probably dont have it i’ll probably install one or just sell the truck and buy one with the g80

That is correct, would not recommend the 3.08 gearing to anyone unless they do at least 85% interstate cruising at 70mph +. It makes the truck feel so much slower and sluggish even when empty. I have towed 7500 pounds with my truck though and it felt perfectly fine, the 6200 lbs limit is a little conservative imo, although I wouldnt push it much more than the 7500 lbs load I had. If I wined up having this truck for a while, I do plan to 3.42 swap it, tremendous difference in drivability
@notasolution I have a 2015 Z71 4x4 LT/2LT 5.3 crew cab and didn't know anything about the GU4. I bought a 15ft aluminum boat with a 2cyl 30hp engine, trolling motor and 2 new batteries and couldn't figure out why my truck sucked pulling it. Found out about the GU4 and was about ready to trade it in for a Ford or Ram lol. The 5.3 LT engine is a decent engine but has no top end. I use Mobil1 advanced full synthetic oil and a can of LiquiMoly oil additive every oil change to stop the ticking from the afm.
I just found out my 07 gmc sierra has g80 code! I jus need some New snow tires! Thanks brother!🍕🍻✌
On the newer Chevrolet trucks you have to scan the QR code on the pillar next to the driver door.
If you hold the traction control button it will turn off both the traction control and stabilitrak 👍
This was very helpful. Thank you!

wtf?
Mine engaged after I turned off my tc and smashed on it, now need to know how to disengage it
It just disengages by itself after driving a little bit, no action from the driver required other than cruise her right on down the road
@@notasolution thanks for the reply, it disengaged after taking it around the lot
Does the g80 come exclusively on the Z71 trucks?
No not at all, my truck is not a z71, it's just a 2LT and I've seen it on fleet spec base model 2wd work trucks as well. I believe it was an independent option for almost any trim level
is it only locked in 4 low ?
how has your transmission held up ? how many miles on it ?

did you do a trans flush when you did the filter and trans fluid on your truck?
@@Jake_Hynds no I didnt do a full flush, I just dropped the trans pan, let all the fluid drain out that came out of it just from dropping the pan, cleaned the pan out, changed the filter and put it back together and filled it back up.
I have a 2003 Suburban 2WD with G80 and Traction Control. Would I also need to disable Traction Control for the G80 to engage?
Dont think so, no
Shouldnt have to in the older ones, the traction control back then was much less constraining in terms of allowing wheel slip
where did you get your push bar with lights from ?

do you also want to turn of the stabilitrak
You got the GU4 gearing. Horrible for towing with a embarrassing pathetic 6,200lbs max towing lol.
