Restore Peak Performance to Your GM Vehicle
Is your 1997 Buick Regal, Grand Prix, or another GM classic suffering from frustrating issues like erratic shifting, a persistent check engine light, poor fuel economy, or a no-start condition? Before you start replacing expensive sensors or transmission components, the root cause is often the vehicle’s central computer: the Powertrain Control Module (PCM). This module is the brain of your engine and transmission, and when it fails, it can create a cascade of problems that are notoriously difficult to diagnose. This replacement 1997 Regal Powertrain Control Module is the reliable, straightforward solution to get your car running smoothly again.
Expert Pro Tip: A Common Misdiagnosis
In my 20+ years in the shop, I’ve seen countless 3.8L GM vehicles brought in for what the owner thought was a failing transmission. They’d report harsh shifts, slipping between gears, or a failure to shift altogether. After spending hundreds on fluid changes or diagnostics, the problem remained. In many of these cases, the actual culprit was a failing PCM. The module was sending incorrect signals to the transmission solenoids. Before condemning your transmission, always consider the PCM, especially if you have other intermittent electrical symptoms.
The Easiest Repair: Programmed Specifically for Your Car
Forget about expensive dealership visits and the hassle of finding a shop with the right equipment to program a new module. We handle the complex part for you. When you purchase this PCM, simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians will then program the module with the latest, most stable software updates directly from GM. This ensures that the unit is perfectly matched to your vehicle’s specific configuration, including engine size, transmission type, and any factory options like a supercharger. It arrives at your door ready for installation.

Plug-and-Play Installation: No Dealer Visit Required
Installing your new 1997 Regal Powertrain Control Module is a simple process that you can do in your own driveway. Follow these steps for a successful installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most of these GM models, the PCM is located inside the air filter box in the engine compartment. You may need to remove the air filter assembly for access.
- Disconnect the Connectors: Carefully unclip and remove the electrical wiring harnesses from the old module. Inspect the pins on the connectors for any corrosion or damage and clean them with a dedicated electronics cleaner if necessary.
- Swap the Modules: Unbolt the old PCM and remove it. Mount the new, pre-programmed module in its place.
- Reconnect Everything: Securely plug the wiring harnesses into the new PCM, ensuring they click into place. Reinstall the air filter assembly.
- Final Step: Reconnect the negative battery terminal. The vehicle may need to run for a few minutes to complete its internal relearn procedures.
