Expert Insight: The Critical Role of VIN Programming
As a veteran tech, I’ve seen countless headaches caused by improperly matched control modules. On these late-90s GM vehicles, the PCM is the central hub, controlling everything from fuel injection and spark timing to transmission shift points and the Passlock security system. Simply installing a used computer without correct programming will, at best, cause performance issues and, at worst, prevent the vehicle from starting at all. By flashing this Programmed 09355699 PCM with your specific VIN, we ensure all factory-calibrated settings are perfectly matched, just like a new part from the dealer, saving you time, money, and immense frustration.
Frequently Asked Questions
Do I need to do any additional programming after installation?
No, the unit comes fully programmed to your VIN. However, you may need to perform a simple security relearn procedure (often called a VATS or Passlock relearn) which takes about 30 minutes and requires only your ignition key. We include instructions to guide you through this easy process.

After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
