Is your 1997 GM vehicle suffering from perplexing issues like stalling, erratic shifting, or a persistent Check Engine Light? The Powertrain Control Module (PCM), the electronic brain of your engine and transmission, is often the culprit. This replacement PCM, part number 19109047, is the definitive solution to restore your vehicle’s performance, reliability, and efficiency. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships, ensuring a seamless, plug-and-play installation process.
Is Your Vehicle Exhibiting These Symptoms?
- ✔ Unexplained Check Engine Light illumination, even after replacing sensors.
- ✔ Harsh or delayed automatic transmission shifting.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ A complete no-start condition where the engine cranks but won’t fire.
- ✔ Poor fuel economy that has gradually worsened over time.
- ✔ Communication errors with diagnostic scan tools.
- ✔ False error codes for sensors that have already been replaced.
From the Diagnostic Bay
We had a 1997 Buick Regal with the supercharged 3.8L come into the shop with a complaint of intermittent stalling and a transmission that would slam into gear. The owner had already spent a small fortune replacing the mass airflow sensor, crank position sensor, and even the transmission solenoids based on the codes he was getting. Nothing worked. When we hooked up our professional scanner, we noticed the data stream from the PCM was dropping out intermittently. The module itself was failing internally, sending corrupt signals that made other good components appear faulty. We installed a VIN-programmed PCM, performed the security relearn procedure, and the car ran like it just rolled off the assembly line. This is a classic case where the root cause is the central computer, not the components it’s monitoring.
The Heart of Your Vehicle’s Performance
The PCM in your 1997 GM vehicle is a critical component responsible for managing dozens of complex systems. It controls everything from fuel injection timing and spark advance to transmission shift points and emissions equipment. When it begins to fail, the symptoms can be widespread and confusing. Heat, vibration, and age can cause internal circuits and solder joints to degrade, leading to the unpredictable behavior you may be experiencing. Simply swapping in a used module from a junkyard won’t work, as it’s not programmed for your car’s specific options, engine, and VIN, which can lead to even more problems or a no-start situation.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive an order confirmation email. Simply reply to that email with your 17-digit VIN, or use our website’s contact form with your order number and VIN.
Is this part difficult to install?
Installation is straightforward for anyone with basic mechanical skills. It typically involves disconnecting the vehicle’s battery, locating the old PCM, unplugging the wiring harnesses, unbolting it, and then installing the new one in reverse order. No special tools are usually required.
Will I need to do anything after installation?
After installing the new PCM, you will need to perform a security relearn procedure, also known as a VATS relearn. This syncs the new module with your vehicle’s anti-theft system. It’s a simple procedure that involves turning the key and waiting, and we can provide instructions.
