Mike

6JT component computer sel suspension
7JT component computer sel suspension
8DH compontent LH RR Computer sel suspension
9DH component RH RR Computer sel suspension

Those are the only ones out of that list that are good through GM. And don't ask me what they mean. lol
 
Thanks everyone for the info, I had searched everywhere. But yes I have noticed also that some of the RPO codes are very cryptic. Maybe there is a special decoder ring we need.

Thanks
 


some of them could also be part of the build record, such as column options, interior, etc. They use those codes at the factory to determine where certain parts that weren't assembled at Fairfax came from.
 
Go ask the dealer. My hook up at the dealer punched in my VIN and printed off everything about it (date and time of completion, RPOs and all definitions, etc).
 
If I give the dealer my VIN, it'll pull up RPOs for a 94 Z24. My tranny was shipped from a warehouse, so no VIN. I want to know if I have a M15, what do I have. Also, if I had the 9YFB code, what does that mean. I've searched for hours and can't seem to find those answers.
