2018 Silverado Gear Ratio Identification

[SFAHank]

I can’t figure out what my gear ratio is. I’d like to know how much my truck will/won’t haul. Rather than the normal door jam/glove box sticker showing the RPO codes or Service Parts ID code, my truck has a QR code. A QR reader app gave me the following codes:

 

AG1

AXK

AY0

AZ3

CJ2

C5Z

DL8

EF7

E63

FHO

G1K

H0U

IO6

I18

JD9

L83

MAH

MSL

MYC

NP5

NTB

QT0

RC4

RD4

RUF

UDD

UQ3

U2K

V8D

WMJ

X88

Z60

1LT

4AA

6YB

7YB

8X2

9X2

 

Please help. Thanks.

Should be a GT or GU code. Connect with GM customer service on the site here and request a build sheet.

Look in your glove box. There should be a code that starts with Gu. You most likelyhave GU6 which is 342

that sticker does not exist in the glove box on the new ones.

I got my build sheet by sending a PM to the GM customer service account on this forum. You provide your VIN and they e-mail you the full build sheet. I don't know if they still respond. But somehow you can reach out directly to them, or ask your dealer for it.

 

My sheet has 99 codes on it, so you are only seeing less than half of them from the QR scanner. That sucks.

the OP has a 2018. I always forget you guys who use the mobile site can't see the signatures.

I sent a message to customer service on this site several days ago and still haven’t heard back
