Get Your GM Truck Back on the Road with a Reliable, Programmed PCM
Is your trusty Chevrolet or GMC truck, van, or SUV suddenly running rough, stalling, or refusing to start? A failing Powertrain Control Module (PCM) can bring your work or family vehicle to a dead stop, causing major frustration and downtime. This fully programmed engine control module is the straightforward, dependable solution to get your vehicle running properly again. We take a genuine, used OEM computer and flash it with the latest official GM software, tailored specifically to your vehicle’s VIN. This means you get a reliable part that’s ready to install right out of the box, with no need for an expensive trip to the dealership for programming.
Common Symptoms of a Failing PCM & Your Solution
If you’re experiencing any of the following issues, a faulty PCM is the likely culprit. This unit is the definitive fix for problems stemming from the engine computer itself, such as:

- Check Engine Light with internal processor error codes (e.g., P0601, P0605)
- Poor fuel economy and reduced engine power

Expert Insight: Why VIN-Specific Programming is Critical
As a technician, I’ve seen countless drivers try to save a few bucks by pulling a computer from a junkyard and hoping for the best. On these 90s GM trucks, that almost never works. The PCM isn’t just a simple box; it’s programmed with specific details for the original vehicle’s engine size, transmission type, gear ratios, and even tire size. Our VIN-flashing process ensures that the Programmed 09366810 PCM you receive is an exact match for your vehicle’s factory configuration. This prevents a host of problems, from incorrect shift points to fuel delivery issues, ensuring your truck runs exactly as the engineers intended.
Frequently Asked Questions
Do I need to do any programming after I install it?
No. This PCM comes fully programmed to your VIN. In some cases, you may need to perform a simple security relearn procedure, which typically involves turning the key on and off a few times. Instructions are readily available online for this process and it requires no special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN. We cannot program and ship your part without it, so please send it as soon as possible to avoid delays.
Is this a new part?
This is a genuine, used OEM part that has been sourced from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped to you.
What if my original part number doesn’t match 09366810 exactly?
This module is a direct replacement for a range of part numbers, including the very common 09355699. Please check the fitment list on this page. As long as your vehicle’s year, make, and model are listed, we will use your VIN to flash the correct calibration for a perfect match.
What is the warranty on this PCM?
This unit is backed by our one-year replacement warranty. This gives you peace of mind that you’re receiving a quality, reliable part.
Will this fix my check engine light?
If your check engine light is on due to an internal fault with your existing PCM (common codes include P0601 through P0606), then this Programmed 09366810 PCM is the correct solution. However, if the light is on for other reasons, like a bad sensor, you will still need to address that separate issue.
