Get Your GM Truck Back in Action
Is your trusty Chevrolet, GMC, or Cadillac suffering from frustrating issues like stalling, erratic shifting, a persistent check engine light, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). Don’t let a faulty computer sideline the vehicle you depend on. This pre-programmed engine computer is the straightforward, reliable solution to restore your vehicle’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of problems that can be difficult to diagnose. If your mechanic is pointing to the computer or you’re seeing diagnostic trouble codes (DTCs) like P0601, P0602, or P0606, this is the part you need. This unit directly addresses issues such as:
- Engine stalling or cutting out while driving
- Failure to start, even with a good battery and starter
- Harsh or incorrect automatic transmission shifting
- Poor fuel economy and loss of engine power
- Check Engine Light that won’t go away
- Communication errors with scan tools
We take the guesswork out of the repair. By providing us with your vehicle’s VIN, we program this unit with the latest GM software updates specific to your truck, van, or SUV. This makes our programmed 9355699 PCM a true plug-and-play solution, saving you a trip to the dealership for expensive programming.

From the Technician’s Bench
“Back in the day, a lot of us would grab a computer from the salvage yard and hope for the best. With these late-90s GM trucks, that’s a recipe for disaster. The Vehicle Anti-Theft System, or VATS, is tied directly to the VIN in the PCM. If they don’t match, the fuel injectors won’t fire, and the truck will never start. Getting a pre-programmed unit like this programmed 9355699 PCM is the only way to do this job right outside of the dealership. It saves hours of headaches and ensures the vehicle starts and runs correctly on the first try.”
Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the correct, updated GM factory software onto the module before it ships. This ensures it’s a perfect match for your vehicle’s specific configuration.
Will I need to do anything after installation?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure (for the VATS/Passlock system) or a Crankshaft Variation Relearn (CASE relearn). These are simple procedures that can often be done without special tools, and instructions can be readily found for your specific model.
Is this a new computer?
No, this is a high-quality, used OEM computer sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped. This provides original equipment reliability at a great value.
How do I know if the PCM is really the problem?
While this part fixes the common symptoms listed, it’s crucial to ensure your vehicle has been properly diagnosed. Check for issues with wiring, grounds, and sensors before concluding the PCM is the fault. A programmed 9355699 PCM is often the final solution, but proper diagnosis is key to any successful repair.
What information do you need from me?
The only piece of information we need is your vehicle’s full 17-digit VIN. You can typically find this on your driver’s side dashboard (visible through the windshield), on your door jamb sticker, or on your vehicle’s registration and insurance documents.
