Is Your GM Truck or Van Running Rough?
If you’re dealing with frustrating issues like a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a problem that affects your vehicle’s reliability and performance. This replacement engine computer is the core of your vehicle’s nervous system, and when it falters, everything from engine timing to transmission function can be compromised. Stop chasing symptoms and address the root cause to get your dependable GM vehicle back on the road.

An Expert’s Note on PCM Replacement
As a technician, I’ve seen countless vehicle owners and even some shops try to save a few dollars by installing a used PCM from a salvage yard. The problem is, a PCM is not a simple swap-out part like an alternator. It’s programmed with the specific VIN, tire size, gear ratios, and options of the vehicle it came from. Installing a mismatched module will, at best, cause a host of new error codes and, at worst, leave the vehicle completely immobilized. Our service of providing a programmed 12576106 PCM eliminates that entire gamble, giving you a part that is guaranteed to communicate with your vehicle correctly from the moment you install it.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. This is essential for us to program the module correctly before we ship it to you.
Will I need to do anything after installing this PCM?
In many cases, you will need to perform a security relearn procedure (often called a Passlock or VATS relearn) so the module recognizes your keys. This is a simple procedure that typically takes 10-30 minutes and does not require special tools. Some applications may also require a Crankshaft Variation Relearn (CASE relearn), which requires a capable scan tool.
How do I know if my original PCM has failed?
Common signs of a failing PCM include a check engine light with communication-related Diagnostic Trouble Codes (DTCs), unexplained stalling, engine misfires, erratic automatic transmission behavior, and a complete no-start condition where the engine cranks but won’t fire. A professional diagnosis is always recommended.
Is this a brand new part?
This is a high-quality, fully tested replacement component that meets or exceeds original equipment specifications. Each unit is inspected and prepared to provide reliable, long-term service.
Will this fix my vehicle’s specific problem?
This programmed 12576106 PCM is a direct solution for a failed module. While it resolves a wide array of common electronic and drivability issues, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix underlying mechanical or wiring issues.
