Restore Your GM Vehicle’s Performance and Reliability
Is your truck or van suffering from a persistent check engine light, erratic shifting, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) can bring your work day or family trip to a grinding halt, causing unnecessary stress and costly downtime. This is the definitive, hassle-free solution to get your vehicle back on the road. This engine computer, part number 89017749, arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN), ensuring a seamless installation and immediate results.

Expert Insight: The Critical Role of VIN Programming
As a technician with over 20 years of experience, I’ve seen countless issues arise from improperly matched control modules. Simply installing a used PCM from another vehicle will almost always result in a no-start condition due to anti-theft system conflicts and mismatched component calibrations. Our VIN-specific programming service isn’t just a convenience—it’s essential. We ensure the PCM recognizes your specific engine, transmission, and options package, preventing frustrating compatibility problems and ensuring your vehicle operates exactly as the factory intended. This is the key difference between a quick fix and a correct, long-lasting repair.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Our technicians will use this number to access the latest GM software and flash the module specifically for your vehicle’s configuration before we ship it to you.
Will I need to do anything after installing this PCM?
In many cases, the vehicle will start and run perfectly after installation. However, some GM vehicles may require a simple security relearn procedure (often called Passlock or Passkey relearn) and a Crankshaft Variation Relearn (CASE relearn). These procedures can often be done without special tools, and instructions are widely available online or in service manuals.
Is this a guaranteed fix for my vehicle’s problem?
This Programmed GM 89017749 PCM is a direct solution for a failed module. While it resolves the vast majority of the symptoms listed, it’s crucial to ensure your vehicle has been properly diagnosed. Other issues, such as faulty wiring or sensors, can sometimes mimic PCM failure.
Do you need my old PCM back?
There is no core charge or need to return your old module for this particular part. You can keep your original unit.
How do I find my VIN?
Your 17-digit VIN can be found on your vehicle’s registration, your insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
