An Expert’s Note on VIN Programming
“Over my 20 years in diagnostics, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply grabbing a used computer from a junkyard won’t work on modern vehicles. Each one is coded with a specific VIN and option set. Our process of programming this 2006 GMC Envoy XL PCM to your exact VIN isn’t just a convenienceโit’s the only way to ensure every system, from the engine timing to the transmission shift points, functions correctly. It’s the difference between a lasting repair and creating a whole new set of electronic headaches.”
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the part is shipped. This 2006 GMC Envoy XL PCM will arrive ready for installation. However, you will need to perform a simple security relearn procedure after installation, which can be done without any special tools and typically takes about 30 minutes. Instructions are readily available online or in your vehicle’s service manual.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your VIN (Vehicle Identification Number). You can also add it to the ‘notes’ section during checkout. We cannot ship your part until we receive this information.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls both the engine and the transmission. If the module is failing, it can send incorrect signals to the transmission, causing harsh shifting, slipping, or failure to shift. If the root cause is electronic, this part is the correct solution.
Is this compatible with other part numbers?
Absolutely. This module is a direct replacement for a wide range of original part numbers, including 12569773, 12588650, 12591647, 12606369, and many more as listed in the full fitment guide. As long as your vehicle is listed, we will program the module to function perfectly.
How can I be sure my old PCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis from a qualified mechanic is always the best course of action. Common signs of PCM failure include communication-related error codes (U-codes) or internal processor fault codes (P06xx series).
