An Expert’s Note on VIN Programming
Many people wonder if they can just grab a module from a junkyard. For modern vehicles, this almost never works. The PCM is the central hub that communicates with nearly every other module in your truck. It’s programmed with your specific VIN, which is tied to the anti-theft system, transmission type, and emissions equipment. Installing a non-programmed module will typically result in a no-start condition. Our process of programming it to your VIN before shipping is what makes this a true plug-and-drive solution, saving you time, money, and a tow to the dealer.
Frequently Asked Questions
Do I need to do anything after I install it?
In most cases, this is a plug-and-drive installation. However, some GM vehicles may require a simple, 10-minute Security Relearn procedure that you can do yourself with just the key. We include instructions for this easy process.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN (Vehicle Identification Number). You can typically find this on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
Will this fix my transmission shifting problems?
If the shifting issues are caused by faulty electronic commands from the PCM, then yes, this module will correct them. The PCM controls the transmission solenoids, and with fresh programming, it will restore crisp, correct shifting patterns. It will not fix internal mechanical failures within the transmission itself.
My original part number isn’t 12588650. Will this still work?
Yes. This module is a direct replacement for a wide range of GM part numbers, as listed in the fitment data. As long as your vehicle’s year, make, and model are listed, and we program it to your VIN, it will function correctly.
Is this a brand new part?
This is a high-quality, tested, and fully functional component that has been programmed with the latest software. It’s a reliable and proven alternative to a costly new part from a dealer, designed to get your vehicle back in service. This is the best value for a dependable 2004-2006 Colorado PCM 12588650 repair.
What does the warranty cover?
This unit is backed by our one-year replacement warranty, which covers the part itself in the event of failure. Please contact us for complete details and procedures.
