Is Your GM Vehicle Running Out of Sorts?
If you’re dealing with frustrating and unpredictable engine problems in your 1996 Buick, Oldsmobile, or Pontiac, a failing Powertrain Control Module (PCM) is often the culprit.

Expert Insight: Why a Pre-Programmed Unit is Essential
Back in the mid-90s, GM’s OBD-II systems were becoming more complex. The PCM in your vehicle doesn’t just manage the engine; it communicates with the transmission and the anti-theft system (VATS/Passkey). Grabbing a used computer from a salvage yard might seem like a cheap fix, but it won’t work. It’s programmed for a different car’s VIN and security key. Our service eliminates that entire headache. By programming the 1996 Buick Park Avenue PCM 88963800 to your specific VIN before we ship, we deliver a part that integrates perfectly with your car’s existing systems, just like the original did. It’s the smartest, most reliable way to get your classic GM back on the road.
Stop chasing down mysterious electrical gremlins and fix the problem at its source. A healthy PCM means a healthy, reliable vehicle you can depend on every day. By providing us with your VIN upon purchase, you’re ensuring a perfect match and a straightforward repair. This is the most effective way to restore the performance and dependability of your car. Order your programmed 1996 Buick Park Avenue PCM 88963800 today and drive with confidence once again.
Frequently Asked Questions
Do I need to have this computer programmed?
No. The main benefit of our service is that we program the module for you before it ships. All you need to do is provide your vehicle’s VIN during or after checkout, and the part will arrive ready for installation.
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer that controls your vehicle’s engine and transmission. It manages fuel injection, ignition timing, emissions systems, and automatic transmission shift points to ensure optimal performance and efficiency.
Will this work with my vehicle’s anti-theft system?
Yes. When we program the PCM to your VIN, we ensure it is correctly configured to communicate with your vehicle’s existing security system, such as VATS or Passkey. In some rare cases, a simple security relearn procedure may be necessary after installation, which can be done without any special tools.
Where can I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this part difficult to install?
For most of the listed GM models, the PCM is located in the engine bay, often within the air filter housing, making it relatively accessible. Installation typically involves disconnecting the battery, unplugging the electrical connectors, and swapping the module. It’s a job many DIY mechanics can handle with basic tools.
