SPID Code inside Glovebox Help
 

Need some help on decoding the other codes on. I know the M35AA is for power glide transmission. Where do I find a site to decode all the other codes on the glovebox?

This site is a great help for decoding: http://outintheshop.com/options.html

As Hutch says post a picture of the SPID label and we can help here too.

Good input thus far.

One other nuance I will mention is that the "M35" portion is the actual three character RPO code. You may have some leading or trailing characters (like the "AA") that you can disregard for now as you research the RPO codes.
