RPO Codes are a system that GM uses to identify which parts and options are on any particular vehicle that they manufacture. RPO codes are typically placed in the glove compartment, which allows you to view the options on your vehicle without ever cracking the hood, or crawling under the car. GM Transmission RPO Codes start with the letter M.
