Get Your GM Truck Running Right Again
Is your trusty GMC Sierra, Chevy Silverado, or Suburban letting you down? If you’re dealing with frustrating issues like a persistent Check Engine Light, rough idling, stalling, or erratic transmission shifting, a failing Powertrain Control Module (PCM) is often the culprit. Don’t let a faulty computer sideline your workhorse. This pre-programmed PCM is the definitive, straightforward solution to restore your vehicle’s performance and reliability, getting you back on the road with confidence.
Common Symptoms of a Failing GM PCM & Your Solution
A vehicle’s PCM is its brain, controlling everything from fuel mixture and spark timing to transmission shift points. When it fails, it can cause a wide range of problems that are often misdiagnosed. If you’re experiencing any of the following, this module is your fix:
- Check Engine Light: Particularly for codes like P0601 (Internal Control Module Memory Check Sum Error) or other module-specific faults.
- No-Start or Stalling: The engine may crank but refuse to start, or it might stall unexpectedly while driving.
- Poor Performance & Fuel Economy: A noticeable drop in power, hesitation during acceleration, and a sudden decrease in MPG.
- Erratic Shifting: Harsh or delayed gear changes from your automatic transmission.
- Communication Errors: Your mechanic’s scan tool is unable to communicate with the PCM.
This isn’t just a replacement part; it’s a complete solution. We use your vehicle’s VIN to flash this module with the latest GM-authorized software updates, ensuring it works perfectly with your specific configuration right out of the box. This process corrects factory bugs and optimizes performance beyond what your original module could deliver.

Expert Insight: Why VIN Programming is Critical
On these late-90s GM vehicles, the PCM is tied directly to the vehicle’s options and security system (VATS/Passlock). Simply swapping in a used computer from another truck won’t workโit will trigger the anti-theft system and the vehicle won’t start. Our VIN-programming service is essential. We configure the module to match your truck’s exact specifications, from engine and transmission type to axle ratio. This ensures all systems communicate correctly and avoids a cascade of frustrating electronic problems. When you receive our Programmed GMC 2500 PCM 09366810, the hard part is already done for you.
