An Expert’s Note on Mid-90s GM Electronics:
“I’ve worked on these 3.1L, 3.4L, and 3.8L GM engines for over two decades. The move to OBDII in 1996 made the PCM the undisputed brain of the vehicle. Unlike older computers, you can’t just swap one from a junkyard. The VIN-specific programming is essential for everything from the anti-theft system to transmission shift points. Getting a pre-programmed unit like this one is the single most reliable way to fix complex electronic issues and avoid the common headaches that come with trying to use a non-programmed module.”
Don’t let a faulty computer keep your dependable car off the road. This is the straightforward, reliable fix you’ve been looking for. By ordering this 1996 Buick Regal PCM 88963800, you’re not just buying a part; you’re investing in restored performance and renewed confidence in your vehicle.

Yes. This module is the correct replacement for several service numbers, including 88963800, 16211539, and 16231853. As long as your vehicle’s year, make, and model are on the compatibility list, this is the correct part for you.
Is this a guaranteed fix for my problem?
While this 1996 Buick Regal PCM 88963800 resolves the vast majority of electronic and drivability issues listed, proper vehicle diagnosis is always recommended. This part will fix any problem originating from a failed computer, but it will not fix underlying mechanical or sensor issues.
What does ‘flashed with the newest updates’ actually mean?
Over the life of a vehicle, manufacturers like GM release software updates to fix bugs, improve transmission shifting, or enhance engine efficiency. We ensure your replacement PCM is loaded with the most recent and stable version of this software, giving you a better-than-original performance.
