RPO Codes

[OUMike]

Hey Guys...so after taken some time looking over my VIN codes and the decoder on theis website I had a few questions.

 

1) I have a 94'. Do the VIN codes change from year to year? Ex - Does M30 = 4L60-E for every year?

 

2) Because mine is a few years older than this website lists, where might I go to find the older codes? Maybe we should start a list? I'd be happy to submit what I have.

 

 

Thanks guys.

Mike,

I've been in the GM parts business for over 16 years and yes,some RPO codes do change over the years (M30 hasn't-Its still means 4L60-E)

But some do...Example:"Z06"...We might think of that as a Corvette option,but from 1976 to 1988 RPO code Z06 meant "Luxury Interior"

Another one is "L33" Today its for the 5.3-5300-"H.O." V8 engine for the 1500 trucks,But from 1976 to 1979 it was the code for the 425 c.i.d. V8 engine for the Cadillacs.

So to answer your question,Some codes change meaning,some don't.

Thanks Dale,

 

How might I properly decode that sticker? I would emagine that not much changes from 94 to 98, so I'm confidant the ones I decided are accurate, but I have a lot of blanks.

 

Thanks again

[MS3DALE]

List the blanks you have and I'll try to decode them for you.

Some RPO codes are blank however,They are used for plant build or ordering purposes only and do not have a description.

Heres the ones I got:

 

C5G=5600 LB. GVWR

FWI=ASM.PLANT CODE,FORT WAYNE,IN.,GM TRUCK & BUS PLANT

MXO=MERCHANDISING OPTION,TRANSMISSION,AUTOMATIC OVERDRIVE

SLM=STOCK ORDER

SVA=CUP HOLDER

TR9=LAMP GROUP,COURTESY

UX1=RADIO,AM/FM STEREO,CASSETTE,EQUALIZER,ETR,W/CLOCK

U16=TACHOMETER,ENGINE

U66=SPEAKER SYSTEM,4,DUAL FRONT DASH MOUNTED,EXTENDED RANGE REAR QUARTER MOUNTED

VXS=VEHICLE COMPLETE (YOU HAD THIS AS "VX5" BUT I THINK ITS "VXS")

X88=MODEL,CHEVROLET (YOU HAD THIS AS "XBB" BUT I THINK ITS "X88")

ZQ2=DRIVER CONVENIENCE PACKAGE (TILT WHEEL/DELAY WIPERS)

ZQ3=DRIVER CONVENIENCE PACKAGE II (POWER WINDOWS/POWER LOCKS)

15D=TRIM COMBINATION,CLOTH,MEDIUM SLATE GRAY

6WK=COMPONENT FRT. LH COMPUTER SELECTED SUSPENSION

7WK=COMPONENT FRT. RH COMPUTER SELECTED SUSPENSION

 

I couldn't come up with anything for the "R" codes,Most times the "R" codes are sales control items.

Also check "15Z" for it possibly being "152" and I think "RBT" should be "R8T"

If "152" is it that is for:TRIM COMINATION,MEDIUM SLATE GRAY,LEATHER

And on "R8T" it is for:SALES CONTROL ITEM 69 PROCESSING OPTION

I had a '94 K1500 also and I just ran my VIN for the codes and I also had the "R8T" and "R7R" codes on my truck.
