Is Your 1997 GM Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
As a mechanic with over two decades of experience, I’ve seen countless 1997 GM cars and vans come into the shop with frustrating, hard-to-diagnose issues. The owner has often replaced sensors and other parts, but the problem persists: harsh shifting, poor fuel mileage, a no-start condition, or random stalling. More often than not, the root cause is a failing Powertrain Control Module (PCM), the electronic brain of your vehicle.
This isn’t just a replacement part; it’s a complete, reliable solution. We take a quality-tested module and flash it with the latest official GM software calibration specifically for your vehicle. All you have to do is provide your Vehicle Identification Number (VIN) after purchase, and we handle the rest. The module arrives at your door ready to install, saving you a costly trip to the dealership for programming.

This module is the definitive fix for a wide range of performance issues. By replacing your old, failing computer, you’re restoring the critical link that controls your engine and transmission.

Expert Pro Tip from 20+ Years on the Job
Before you plug in your new PCM, take a moment to closely inspect the wiring harness connectors. Over the years, the plastic can become brittle and the metal pins inside can get corroded or bent. I’ve seen new modules get damaged instantly because of a bad connector. Use a small pick and some electrical contact cleaner to ensure every pin is straight and the connector is free of any green or white corrosion. This five-minute check can save you a massive headache.
Easy Installation for the DIY Mechanic
You don’t need to be a master technician to replace your 1997 Lumina Powertrain Control Module. The process is straightforward and can typically be done in under an hour with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On most of these 1997 GM models, the PCM is located in the engine bay, often inside or near the air filter housing.
- Disconnect the Harnesses: Carefully unclip and remove the electrical connectors from the old module. Note their orientation.
- Swap the Modules: Unbolt the old PCM and secure the new one in its place.
- Reconnect Everything: Firmly plug the wiring harnesses into your new module and reconnect the negative battery terminal.
- Final Steps: Start the vehicle. It may run a little rough for the first few minutes as it completes its internal relearn process.
