Restore Your GM Truck’s Performance and Reliability
Is your trusted GM truck, van, or SUV suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? A failing Powertrain Control Module (PCM) is often the culprit behind these perplexing problems. This isn’t just an inconvenience; it’s a roadblock that keeps you from getting work done or relying on your vehicle. This pre-programmed PCM is the definitive, straightforward solution to get your workhorse back on the road, running just as the factory intended.

A Veteran Technician’s Insight: I’ve worked on hundreds of these GMT400 and GMT800 platform trucks. They are some of the most durable vehicles ever built, but their one true Achilles’ heel after 20+ years is the electronics. The original capacitors and processors inside these PCMs simply wear out. Swapping in a properly Programmed 09355699 PCM is like giving your truck’s brain a new lease on life. It’s often the single most effective repair to solve a host of mysterious electrical and performance gremlins, ensuring that legendary Vortec engine runs strong for another hundred thousand miles.
Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your Vehicle Identification Number (VIN) is essential because it contains specific information about your truck’s engine, transmission, emissions system, and factory options. We use the VIN to load the exact, correct GM software onto the PCM, making it a perfect match for your vehicle and ensuring a true plug-and-play installation.
Is this part difficult to install?
For most of these GM trucks and vans, the PCM is located in the engine bay and is held in by a few bolts and electrical connectors. Installation is typically straightforward for a DIY mechanic with basic tools. The most important step is to disconnect the vehicle’s battery before starting the replacement.
Will this fix my specific problem?
This PCM is the solution for failures of the module itself. Common symptoms are listed above, often including internal processor error codes. While it solves a wide range of issues, it’s always best to have a proper diagnosis to confirm the PCM is the point of failure and not a sensor or wiring issue.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate for these vehicles as it controls both the engine and transmission. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to a computer that only manages engine functions.
What happens after I place my order?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship the part until we receive it. Once we have your VIN, our technicians will program the module, test it, and ship it out to you, ready for installation.
