Is Your 1997 Lumina Running Rough, Stalling, or Showing a Check Engine Light?
As a technician with over two decades of experience under the hood, I’ve seen countless GM vehicles from this era come into the shop with frustrating, hard-to-diagnose issues. Symptoms like erratic automatic transmission shifting, a sudden no-start condition, poor fuel economy, or a persistent check engine light often point to one culprit: a failing Powertrain Control Module (PCM). The PCM is the brain of your vehicle, and when it starts to fail, it can cause a cascade of problems that can be mistaken for other, more expensive repairs.
The Right Part, Programmed and Ready to Install
This isn’t just a replacement part; it’s a complete solution. We are providing a high-quality Powertrain Control Module, a direct replacement for part numbers 19109047 and 16227797. The most critical service is already done for you: before we ship it, our technicians will program the module using your vehicle’s specific Vehicle Identification Number (VIN). This ensures it has the latest GM software updates and communicates perfectly with your Lumina’s engine, transmission, and other systems right out of the box.
From the Shop Floor: A Real-World Scenario
Just last month, a customer brought in a ’97 Grand Prix—which uses this exact same PCM—convinced his transmission was shot. It was shifting hard and unpredictably. He was ready for a multi-thousand dollar bill. After hooking up the scanner, I saw no specific transmission fault codes, but the data from the PCM was erratic. Instead of a transmission rebuild, we swapped in a correctly programmed PCM. The car drove off shifting as smoothly as it did new. This is a classic case where the brain (PCM) was giving bad commands, not the body (transmission) failing. This is why a reliable, correctly programmed 1997 Lumina PCM is so crucial.

Easy Installation for the DIYer or Professional
Replacing the PCM on your 1997 Lumina is a job most people with basic tools can handle in their own driveway. Follow these simple steps to get your car back in top shape.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On most of these GM models, the PCM is located inside the vehicle’s air filter box in the engine bay. You will need to remove the air filter cover to access it.
- Disconnect the Harnesses: Carefully unclip the electrical wiring harnesses from the old module. They have locking tabs that need to be released.
- Remove the Old Module: Unbolt the PCM from its mounting bracket or housing.
- Install the New Module: Seat your new, pre-programmed PCM into the mounting location and secure it.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reassemble the air box and reconnect your negative battery terminal.
