Our mandatory VIN programming ensures the PCM we send you is a perfect digital match for your vehicle. This critical step prevents frustrating no-start issues and eliminates the need for an expensive trip to the dealer for programming. It’s the difference between a quick driveway fix and a week of headaches.

Frequently Asked Questions
What is the process after I place my order?
After you purchase the PCM, you will need to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information. Once we receive your VIN, we will program the module and typically ship it within 1-2 business days.
Is this part truly plug-and-play?
Yes, for the most part. The module comes fully programmed to your VIN. However, like any GM vehicle of this era, you may need to perform a simple security relearn procedure which takes 10-15 minutes and involves only your ignition key. We include easy-to-follow instructions for this process.
Do I need to send my old computer (core) back?
No, there is no core charge or requirement to return your old module for this particular part. You can keep it or dispose of it as you see fit.
Will this fix my transmission shifting problems?
The PCM controls both the engine and the transmission. If your shifting issues are caused by faulty electronic commands from a failing module, this part is the correct fix. However, it will not fix internal mechanical failures within the transmission itself. Proper diagnosis is always recommended.
How does the one-year warranty work?
This part is backed by our one-year replacement warranty. If the module fails within one year of the purchase date, we will provide a direct replacement. Please contact us for instructions on how to start a warranty claim.
Is this compatible with other vehicles?
Yes, this PCM fits a wide range of 2004-2006 GM trucks and SUVs, including the Trailblazer, Envoy, Colorado, Canyon, and H3. Please check the detailed fitment list in the product description to confirm compatibility with your specific vehicle and options.
