- Engine stalling, stumbling, or running rough
- Unexplained drop in fuel mileage
- Transmission shifting harshly or at the wrong times
- Vehicle refuses to start, even with a good battery and starter
- Communication errors with diagnostic scan tools
This module is engineered to be the ultimate fix for these problems. By providing us with your VIN, you receive a perfectly matched and updated 2006 GMC Envoy XL PCM that integrates seamlessly with your vehicle’s systems, eliminating the need for an expensive trip to the dealership for programming.

While some GM vehicles may require a simple 10-15 minute key relearn procedure (turning the key on and off), this pre-programming step handles the most complex part, preventing the common “crank but no start” issue that occurs with unprogrammed modules.

Frequently Asked Questions
What exactly does the PCM do in my Envoy XL?
The Powertrain Control Module (PCM) is the master computer for your vehicle. It controls all aspects of the engine and transmission, including fuel injection, spark timing, emissions systems, and automatic transmission shift points, to ensure optimal performance, efficiency, and safety.
How do I provide my VIN number?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
Will I need to do anything after I install it?
In most cases, this is a plug-and-drive solution. However, some GM vehicles may require a simple security relearn procedure that takes about 10-15 minutes and involves cycling the ignition key. This procedure does not require any special tools, and we can provide instructions if needed.
