Is Your GM Truck or Van Running Rough?
If you’re dealing with frustrating issues like a persistent check engine light, erratic shifting, stalling, or a complete no-start condition, the culprit is often a failing Powertrain Control Module (PCM). As the electronic brain of your vehicle, the PCM controls everything from fuel mixture and spark timing to transmission behavior. When it fails, your dependable workhorse can become unreliable and undriveable. This isn’t just an inconvenience; it’s a problem that affects your work, your projects, and your peace of mind.
The Smart Solution: A VIN-Programmed Replacement
Forget expensive dealership visits and the hassle of finding a shop that can program a new module. This is a dependable, used OEM PCM that arrives at your door ready for installation. We take your vehicle’s VIN and flash this computer with the latest, most stable software updates directly from GM. This ensures it communicates perfectly with your specific engine, transmission, and all related systems, restoring original performance and reliability.
Expert Pro Tip: Check Your Grounds First!
In my 20+ years in the shop, I’ve seen countless PCMs replaced unnecessarily. A customer’s ’99 Silverado 1500 (which uses this exact same module) was towed in for a no-start. The owner was convinced the PCM was dead. Before swapping it, I did my standard check of the main engine-to-chassis ground straps, especially the one near the thermostat housing. It was corroded and barely making contact. After cleaning and tightening it, the truck fired right up. Always verify your main grounds are clean and tight before condemning the PCMโit can save you time and money.

- Locate the PCM: On most of these GM trucks and vans, the PCM is located in the engine compartment, typically on the driver’s side fender well or near the battery.
- Disconnect Connectors: Carefully unlatch and remove the wiring harness connectors from the old PCM. Inspect the pins for any corrosion or damage.
- Swap the Module: Unbolt the old PCM and remove it. Mount your new, pre-programmed module in its place.
