Having a hell of a time finding the gear ratio on this '18 sierra 4x4 SLT.  Apparently GM stopped putting RPO stickers in the vehicle, and replaced with a QR scannable barcode...I guess because the $.19 cost of the stickers couldn't be offset by a $55k+ MSRP on the truck?  So I scanned the QR code and got back an what looks like an incomplete list, don't see anything about the gear ratio (GT4, GU4, GU5, GU6, G80) because the list gets cut off with a bunch of ,,,,,.  Downloaded 5 different QR apps approved by GM for the new RPO sticker, same result.

Someone posted a link in here that took me to a GM site with all sorts of build docs on the 2018s, found a table.  Based on my model (TK15543) and 5.3L (L83) engine, I have the following.  I'm the second column w/ 3.08, 3.42, and 3.73 listed out.  So I'm basically right where I started.

I don't have the original sticker, so not sure how to go about getting this info other than getting a build sheet from the dealer (which I will do on Friday if needed). My truck is a texas edition, w/ trailer brake and tow button on gearshift.  Never towed anything heavy enough to care, but looking to buy a ski boat and want to have the facts.  Anyone know how to figure this out other than dealing with the dealership?

 

Thanks

You can try compnine, but I'm not sure the info you get will be much more complete.  Dealer or a call to GM customer service may be the best route.

Your list is not cut off. The last one is 636R, which is the paint code.

They just don't provide the gear ratio code in the list anymore. See here -> https://gm-techlink.com/?p=9801

 

You would need to get the full build sheet from your dealer. Or possibly from someone at GM, but good luck getting someone on the phone. There was a GM customer care account on this forum a couple years ago. They actually e-mailed my build sheet to me, but i don't think they have been active in quite a while.

I'd just call your dealer.

Which transmission do you have and do you have Max Tow.  We can tell you from that.

I have had the same problem few months ago.  I went to the service centre of my dealer and one of the mechanics used his account at GM Global Connect (https://www.autopartners.net/) to pull the data and print it out for me.

I have heard that GMC and Chevrolet Chat centre can send that to your email address using your car’s VIN

Technology will be the death of us yet!  :smash:    LOL

They eliminated RPO codes in the glovebox so in a few years they can charge shops access to the “scannable” code. 

 

Data aint free.

Email your VIN to [email protected]. They'll send you a build sheet.

Unfortunately they have stopped doing this. Should still be able to get a copy from most local stealerships (assuming they are customer friendly) talk to the parts counter people about printing one off.

    • It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is. 
    • I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.    
    • Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.
    • If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.
    • It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.
