An Expert’s Note on Your 1997 GM Truck
As a technician with over two decades of experience, I’ve seen countless 90s-era GM trucks sidelined by a bad PCM. These vehicles are known for their durability, but the original electronics can fail over time. The key to a successful repair isn’t just swapping the boxโit’s the programming. A correctly flashed 1997 Chevrolet 3500 PCM 16229684 ensures the 4L60E or 4L80E transmission shifts at the right points, the fuel injectors fire with precise timing, and the engine operates at peak efficiency. We handle that critical step for you, so you can be confident the job is done right the first time.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer of your vehicle. It controls all aspects of the engine and transmission, including fuel delivery, ignition timing, emissions systems, and automatic shifting. When it fails, it can cause a wide variety of serious performance issues.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your order until we receive your VIN, as the programming is essential for the part to function in your vehicle.
Will I need to do any additional programming after installation?
No. This module comes fully programmed to your vehicle’s VIN. In most cases, it is a simple plug-and-play installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which is a simple process that can be done without special tools. Instructions are widely available online for this procedure.
Does this fit models other than the Chevrolet 3500?
Yes. This 1997 Chevrolet 3500 PCM 16229684 is compatible with a wide range of 1997 GM models, including the C/K 1500/2500/3500 pickups, Suburban, Tahoe, Yukon, S10/Blazer, Express/Savana vans, and more. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
