Is Your Trusted GM Running Rough?
If your 1997 Buick, Pontiac, or Chevy is suffering from bizarre electrical gremlins, poor shifting, a no-start condition, or a persistent Check Engine Light that won’t go away, a failing Powertrain Control Module (PCM) is the most likely culprit. As the central computer for your engine and transmission, its health is critical to your vehicle’s performance and reliability. Stop throwing parts at the problem and get the definitive solution that restores your car to its smooth, dependable self.

Expert Insight: Why 90s PCMs Fail
As a technician with over two decades of experience, I’ve seen countless modules like the 1997 Park Avenue PCM 16227797 fail. The cause is often simple aging. After 25+ years of constant heat cycles under the hood, the internal capacitors and solder joints can degrade, leading to intermittent connections and unpredictable behavior. It’s not a matter of if, but when. Replacing the unit with a professionally programmed module isn’t just a repair; it’s a critical step in preserving the long-term health and drivability of your vehicle, ensuring it’s ready for many more miles.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply reply to your order confirmation email with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your car.
Is any additional programming needed after installation?
In most cases, no. This PCM is designed for plug-and-play installation. However, some vehicles may require a simple “Security Relearn” procedure, which can typically be done without special tools and takes only a few minutes. Instructions are readily available online for your specific model.
Will this fix my transmission problems?
If your transmission issues, such as hard shifts or delayed engagement, are electronic in nature, this module is very likely the solution. The PCM controls all transmission functions, including shift points and line pressure. A failing module is a common cause of these exact symptoms.
Is this a new or used part?
This is a genuine, factory OEM component that has been meticulously inspected, tested, and programmed by our expert technicians. It meets or exceeds all original performance specifications, ensuring reliability.
What if my vehicle is modified?
The programming we provide is for a stock vehicle configuration based on the VIN you supply. If you have significant performance modifications (such as a different engine, transmission, or fuel injectors), please contact us before ordering to ensure compatibility.
Does this fit models without the supercharged engine?
Yes, the 1997 Park Avenue PCM 16227797 is compatible with a wide range of GM vehicles from this era, including those with the naturally aspirated 3.8L V6 and the 3.4L V6. Our VIN-specific programming ensures it has the correct software for your exact engine and options.
