Restore Your Vehicle’s Brain, Restore Your Drive
Is your truck or SUV suffering from erratic behavior, a persistent check engine light, or failing emissions tests? These are classic signs of a failing Powertrain Control Module (PCM), the central computer of your vehicle. A faulty PCM can cause a cascade of frustrating problems, from rough idling and poor fuel economy to harsh transmission shifts and even a no-start condition. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s performance and reliability. We offer the definitive solution: a direct-replacement, professionally programmed PCM that gets you back on the road with confidence.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing PCM is the likely culprit. This unit is the direct fix for:
- Check Engine Light (CEL) with communication error codes (e.g., U-codes)
- Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606
- Poor or inconsistent automatic transmission shifting
- Engine stalling, stuttering, or misfiring
- Reduced fuel efficiency
- Failure to pass emissions testing
- Complete no-start condition where the engine cranks but won’t fire

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I can’t stress this enough: a PCM is not a one-size-fits-all part. Your vehicle’s VIN is linked to its specific engine, transmission, axle ratio, tire size, and even emissions equipment. Installing a generic or non-programmed module is a recipe for disaster—it can lead to immediate drivability problems or even damage other components. Our process ensures the Programmed 89017750 PCM you receive is an exact digital clone of the original, updated with the newest software from GM for optimal performance and longevity. We take care of the complex part so you can focus on the simple installation.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information, so please provide it promptly to avoid delays.
Will I need to do anything after installing this PCM?
In most cases, this is a direct plug-and-play installation. However, some vehicles are equipped with anti-theft systems (Passlock, VATS) that may require a security relearn procedure after installation. This procedure is simple, requires no special tools, and instructions are readily available online or can be provided.
Is this the correct part for my vehicle?
This module replaces several service numbers, including 89017750, 12582605, 12589463, and more. Please review the detailed fitment list on this page. The most reliable way to ensure compatibility is to match the service number on your current PCM. If you are unsure, please contact us with your VIN before ordering.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) is most accurate for these GM vehicles as it controls both the engine and transmission. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to a computer that only manages engine functions. For this application, it’s the main computer.
What if my original part number is not listed?
The provided list of compatible service numbers (89017750, 12582605, 12589463, etc.) covers the most common replacements. If your number is not on the list, please contact us with your VIN and original part number to verify compatibility before making a purchase.
