From the Technician’s Bench: We see these late-90s GM trucks in the shop all the time. After two decades of heat cycles and vibrations, the internal connections on the original PCM circuit boards can start to fail. This creates bizarre, intermittent problems that are a nightmare to diagnose. A customer might complain about a random stall once a week. We’ve found that swapping in a solid, tested computer like this Programmed 09355699 PCM often solves the problem instantly, saving hours of diagnostic labor and getting that workhorse vehicle back to being the reliable tool it was built to be.
Frequently Asked Questions
What is a PCM and why does it fail?
The Powertrain Control Module (PCM) is the central computer that controls your vehicle’s engine and transmission. Over time, factors like heat, vibration, and age can cause internal electronic components to degrade, leading to failure.
Do I need to do anything after installation?
This PCM comes programmed to your VIN. However, on some GM vehicles, you may need to perform a simple Security Relearn procedure, which can typically be done without special tools and takes about 30 minutes. Instructions are readily available online for your specific model.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot program or ship the module without your vehicle’s VIN.
Is this a new part?
No, this is a high-quality, used OEM computer that has been carefully removed from a salvaged vehicle, inspected, and tested to ensure it is fully functional before being programmed for you.
What if I have questions about installation?
While we cannot provide vehicle-specific repair advice, we are here to support the product itself. The installation is typically straightforward, involving disconnecting the battery, unplugging the old module, and plugging in the new one.
