Expert Insight: Why VIN Programming is Critical
On these late-90s GM vehicles, the PCM controls everything from fuel injector pulse width to transmission shift points and torque converter lockup. A generic, non-programmed module simply won’t work. Our VIN-specific flashing process ensures the computer has the correct information for your engine size (4.3L, 5.0L, 5.7L), transmission type, and axle ratio. This meticulous process is the key to a successful repair, preventing drivability problems and ensuring your vehicle operates exactly as the factory intended. This is the correct way to replace your programmed 16250279 PCM.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the module is shipped to you. It will arrive flashed to your VIN and ready for installation. You may need to perform a simple security relearn procedure (often called a Passlock or VATS relearn), which can typically be done in your driveway without special tools. Instructions are widely available online for this process.
Where do I provide my VIN?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
