Re: Ultimate RPO Database
lol i forgot what code it was but i saw a hood delete code in there. i wonder how many trucks were built with the hood delete option??

i have the RPO code U63 it says 9 speacker sound. my truck NEVER had more then 2 speckers in the dash. it looks like the dealer got ripped there lol.
94 Lincoln Mark VIII 32V 4.6 about to see 18psi+ on the street. = fun weekend street car

all motors will tell you what they need you just have to learn to speak their language.

Re: Ultimate RPO Database
I have some list that came with my truck. Might have something to do with my truck supposedly being ordered. The RPO for the tranny is "MT1" with a descriptor saying "4 SPD. AUTO. R2". I know the MT1 is a 4L80E but does the R2 part mean anything?
This came from another site: MT1 -- TRANSMISSION, AUTO 4 SPD, HMD, THM R2 (4L80-E)
No clue what HMD is either. Geez.
'98 K2500 ECLB Silverado, 7.4L Vortec, 4L80E, G80-4.10, 4" Rancho, 33X12.50 Pro Comp A/T's, 17" Extreme Alloys

They drew first blood....not me....

Re: Ultimate RPO Database
Very Informative info I thought I had an open Diff but yeah a G80.
The only thing I couldn't find was my tranny Im pretty sure its a 700R considering its a 92 and they started putting the 4L60-E in around 93-94 idk though
This is what I got for my tranny
MX0 16407 P MTC M MERCHANDISED TRANS AUTO PROVISIONS, O/D
and only 5 codes I couldn't find
MD8
QIY
XGM
YGM
ZGM
My guess is some dealership crap
I also found out my truck was built on a Monday.
1992 Chevy Blazer 5.7 ltr 4x4 Victory Red
2005 Chevy Colorado Z71 2WD Black
