RPO codes not on list published on this board

[tomseeley]

I just bought a 2002 Sierra 2500HD duramax/allison. My first new used truck! What a great rig! Got a bit over 18 mpg on the interstate driving it back from Minneapolis to home near Pittsburgh, at ... ahem ... around 65 mpg. I even figured out already how to change a flat.

 

I also figured out how to print the list of RPO codes from this board, and decipher the list in my glove compartment. My question is:

 

There are 21 codes in the list on the glove compatment door that are NOT on the list I printed from this board. I'm only curious, but I'd like to know what they are. Can anyone help me identify these codes? One in particular is strange to be omitted. It's M74, which I know already is the Allison tranny which I obviously have on the truck!

 

No big deal; I'm just wondering why there are so many codes on the truck's list that aren't on the supposedly "official list" I got from this forum.

 

Here's the list:

 

CMD C6W FE9 HVY K68 M74 R9Z SLM TFE TQ3 V10 V73 YD3 YD6 ZY1 1SC 12I 50U (the 0 has a slash through it; I can never remember if that means oh or zero) 6GL 7GL

(the 0 has a slash through it; I can never remember if that means oh or zero)

 

the number zero will have the slash, think of it as crossing it out, nothing there as in zero.
