Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless people try to save a few dollars by grabbing a used PCM from a salvage yard. It almost never works. On these 90s GM vehicles, the PCM is tied to the specific VIN and options of the car it came from. Installing a mismatched module will, at best, not start the car and, at worst, can cause communication errors across other systems. Our process of programming the 1998 GM PCM 9356741 to your specific VIN before shipping eliminates that entire headache. It’s the only way to ensure the job is done right the first time, saving you hours of frustration and diagnostic guesswork.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives fully programmed to the VIN you provide. The installation is plug-and-play. In some cases, a simple security relearn procedure may be required, which takes about 30 minutes and can be done at home without any special tools. Instructions are readily available online for this common GM procedure.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. You can also add it as a note during the checkout process. We cannot ship your part until we have this information.
Is this the correct part for my vehicle?
This 1998 GM PCM 9356741 fits a wide range of GM models from 1998-1999, including the Silhouette, Venture, Grand Am, Malibu, and many more. Please review the detailed fitment list. The most important step is providing your VIN, which allows us to confirm compatibility and program it perfectly for your specific make, model, and options.
What if my original part number is slightly different?
GM often uses several interchangeable service numbers for the same computer. This module is a direct replacement for all service numbers listed in the description, including 09356741, 16236757, 9357034, and others. As long as your vehicle is on the compatibility list, we will program it to function correctly.
What does ‘flashed with the newest updates’ actually mean for my car?
Over the life of a vehicle, manufacturers like GM release software updates to fix bugs, improve transmission shifting logic, or optimize fuel economy. By flashing your module with the latest version, you’re getting a computer that performs better than the one that originally came in your car, addressing known issues from the factory.
