Should say on your window sticker if you still have it. If not, someone I'm sure will chime in with which RPO codes are for which gear ratios (you can find RPO codes in upper glove box on a sticker)

Easiest way to tell is RPO Codes in glove box (silver sticker). RPO GU4 = 3.08...RPO GU6 = 3.42

 

GT4 Rear axle, 3.73 ratio GU4 Rear axle, 3.08 ratio GU5 Rear axle, 3.23 ratio GU6 Rear axle, 3.42 ratio

 

There is a RPO code lookup link in the main documents sticky of the forum here:

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
