Vin number decoding for gear ratio..

Badbird2000 · January 16, 2014

Hey peeps, i am in the market for a new (used) Silverado/Sierra to replace my old worn out Ford. I know... i am a GM guy at heart and had a 20 minute slip in clarity, been paying for it the last 12 years. Just give me some pushrods again! Traded in my 2000 Trans Am... (hence my username)

Anyway, i found a 2011 Silverado LTZ with 13,000 miles on it, 5.3 liter. I have the vin, but can't tell what the rear gears are. I don't want 3.08.. i plan on buying a pop-up to tow and anyway, just don't want 3.08. I have tried looking online at some of the vin decoders, even the ones that were posted here, but i don't see where it lists it. Am i missing it or would it be somewhere else? I have not looked at the truck in person yet, just online.

Thanks for the help!

There is an RPO code lookup, that's what I'd use. All the codes will be in the glovebox and will tell you all the options.

That's not a valid VIN. The last 8 only says it's a FWD Terrain and the whole thing comes up with an error

Look at the codes sticker in your glove box. Look for one of the following codes:

GT4 : AXLE REAR, 3.73 RATIO
GT5 : AXLE REAR, 4.10 RATIO
GT7 : AXLE REAR, 3.33 RATIO
GT8 : AXLE REAR, 4.10 RATIO
GTY : AXLE, WIDE TRACK
GU1 : AXLE REAR, 2.41 RATIO
GU2 : AXLE REAR, 2.73 RATIO
GU4 : AXLE REAR, 3.08 RATIO
GU5 : AXLE REAR, 3.23 RATIO
GU6 : AXLE REAR, 3.42 RATIO
GV2 : AXLE REAR, 5.83 RATIO
GV4 : AXLE REAR, 3.36 RATIO
GV8 : AXLE REAR, 2.72 RATIO
GW4 : AXLE REAR, 3.31 RATIO
GW6 : AXLE REAR, 3.27 RATIO
GW9 : AXLE REAR, 2.93 RATIO

Thanks guys. I guess that's why I was having trouble figuring out what gear is in it. I got the vin off the dealers website who has it for sale. Might try and look at it this weekend.
