A Veteran Technician’s Advice on PCM Replacement
For these late-90s GM trucks and vans, the VIN programming isn’t just a convenience—it’s critical. I’ve seen countless DIYers buy a used computer from a salvage yard only to find their truck won’t start or the transmission shifts horribly. That’s because the PCM is programmed for the donor vehicle’s specific options, gear ratios, and tire size. Our VIN-matching service ensures the GM PCM 09355699 you receive is an exact electronic match for your vehicle, preventing these headaches and getting you back on the road fast.
Frequently Asked Questions
What do I need to provide after purchasing?
After you place your order, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your part without it.
Is this a new part?
No, this is a genuine, used OEM part that has been sourced from a salvaged vehicle. Each unit is tested to ensure it is fully functional before being programmed and shipped.
Will I need to do anything else after installation?
In most cases, the unit is plug-and-play. However, some GM vehicles of this era may require a simple security relearn procedure (also known as a CASE relearn) which can typically be done without special tools. Instructions are widely available online for this process.
How do I know this will fix my vehicle’s problem?
While this part resolves the common symptoms listed, we always recommend a proper diagnosis by a qualified mechanic to confirm the PCM is the point of failure. A thorough diagnosis ensures you are ordering the correct part for your repair.
What does “programming” mean?
Programming, or “flashing,” is the process of loading your vehicle’s specific software and operating parameters onto the computer using your VIN. This ensures the PCM works correctly with your engine, transmission, and all factory options.
