Restore Peak Performance to Your 1997 GM Vehicle
Is your 1997 Buick Park Avenue, Pontiac Grand Prix, or another trusted GM vehicle suffering from perplexing issues like stalling, erratic shifting, poor fuel economy, or a persistent check engine light? The Powertrain Control Module (PCM), the electronic brain of your engine and transmission, is often the root cause. This replacement PCM, part number 19109047, is the definitive solution to restore your vehicle’s reliability and drivability. It arrives at your door fully programmed to your specific vehicle using your VIN, ensuring a seamless installation process.
From the Diagnostic Bay
We had a ’97 Buick Riviera in the shop that was driving the owner crazy. It would randomly stall at red lights and the transmission would shift hard from first to second. The owner had already replaced the mass airflow sensor and the throttle position sensor with no luck. After hooking up our scanner, we saw intermittent communication loss codes. Instead of chasing electrical gremlins for hours, we checked the PCM. A quick swap with one of our VIN-programmed modules solved everything instantly. The car ran like it just rolled off the assembly line. It’s a classic case where the central computer was causing a cascade of confusing symptoms that other parts got blamed for.
Is Your Vehicle Exhibiting These Symptoms?
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty module is a likely culprit:
- ✔ Unexplained Check Engine Light (CEL) illumination
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Noticeable decrease in fuel efficiency
- ✔ Failure to pass state emissions testing
- ✔ Communication error codes with a diagnostic scan tool

Frequently Asked Questions
What is the programming process?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the correct GM-certified software and calibrations onto the module before it is shipped to you. This makes the unit ready for installation upon arrival.
Do I need to do anything after installing this PCM?
In most cases, you will need to perform a simple security relearn procedure, also known as a VATS relearn. This can typically be done without any special tools and involves a sequence of key turns. Instructions are readily available online for your specific model, and it usually takes about 30 minutes.
Is this a brand new part?
This is a high-quality, fully tested replacement part that has been meticulously inspected and prepared to meet or exceed original equipment specifications. The critical service we provide is the professional programming that makes it work correctly with your vehicle.
Will this fix my transmission shifting problems?
The PCM controls both engine and transmission functions. If your shifting problems are caused by faulty electronic commands from the module, then this part is the correct fix. It will resolve issues like harsh shifts, delayed engagement, and incorrect gear selection that are electronic in nature.
How do I provide my VIN?
You can add your VIN in the notes section during checkout or reply to your order confirmation email with the information. We cannot ship your part until we receive the VIN, as the programming is essential for the part to function.
