Restore Your Vehicle’s Brain and Get Back on the Road
Is your 1998 Buick Regal suffering from erratic shifting, poor fuel economy, or a persistent check engine light that just won’t go away? A failing Powertrain Control Module (PCM) is often the frustrating root cause, acting like a broken brain for your engine and transmission. This isn’t just another part; it’s the definitive solution to restore your vehicle’s performance, reliability, and get you driving with confidence again.

A Technician’s Tip: Why VIN Programming is Non-Negotiable
As a veteran tech, I’ve seen countless DIYers get stuck after installing a generic computer from a salvage yard. On these GM vehicles, the PCM is tied directly to the anti-theft system (VATS/Passlock). A non-programmed module won’t recognize your keys, and the car simply will not start. Our process of programming your specific VIN to the module before shipping ensures the computer is ready to communicate with your car’s systems, saving you from a ‘bricked’ vehicle and the headache of towing it to a specialist.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive the VIN, as the programming is essential for the part to function in your vehicle.
Is this really a plug-and-play installation?
Yes, for the most part. Because we program it to your VIN, it will communicate with your car’s systems. However, you will likely need to perform a simple ‘Security Relearn Procedure’ which involves a sequence of turning the key on and off. This procedure takes about 30 minutes and does not require any special tools. We can provide instructions for this.
What if I order the wrong part?
Please double-check the compatible service numbers listed and the fitment chart. Providing us with your VIN allows us to verify compatibility before we program and ship the unit, which helps prevent errors. If you are unsure, please contact us with your VIN before ordering.
Will this fix my car’s specific problem?
This module is a direct solution for issues originating from a faulty PCM, such as the symptoms listed above. While it solves a wide range of problems, it’s always recommended to have a proper diagnosis performed to confirm the PCM is the point of failure before ordering.
Do I need to send my old part (core) back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
