This replacement PCM, part number 9366314, is the definitive solution to restore your vehicle’s reliability and drivability.

The Importance of a VIN-Programmed 1998 Lumina PCM
You can’t simply take a computer from another vehicle and expect it to work. The PCM must be specifically calibrated for your car’s unique Vehicle Identification Number (VIN). This process ensures the module has the correct software for your engine size, transmission type, emissions equipment, and security system (VATS). Our service eliminates all guesswork. When you order, you provide us with your VIN, and our technicians flash the module with the latest GM-certified software updates. This ensures your new 1998 Lumina PCM is a true plug-and-play component, ready for installation right out of the box.
This module is a direct replacement for service numbers 09356741, 16236757, 9357034, 9357440, and 9366314, and fits a wide range of GM vehicles from that era, including the Buick Century, Pontiac Grand Am, Oldsmobile Alero, and many more.
