These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine and transmission. Don’t let a faulty module keep you off the road. This direct-fit replacement PCM, service number 28042802, is the reliable solution to restore your vehicle’s performance, drivability, and fuel efficiency.

Expert Pro Tip
Before condemning your PCM, always check the basics. A weak battery or corroded ground connections at the engine block and frame can cause symptoms that mimic a failed computer. Ensure all power and ground circuits to the PCM have less than 0.1 volts of voltage drop before proceeding with a replacement. This simple check can save you time and money.
The Brain of Your Vehicle, Made Simple
The PCM is arguably the most critical electronic component in your vehicle. It processes data from dozens of sensors to precisely control fuel injection, ignition timing, transmission shift points, and emissions systems. When it fails, the entire powertrain can be affected. Our replacement module eliminates the guesswork and the expensive trip to the dealership. We handle the complex part for you: programming. Simply provide us with your vehicle’s 17-digit VIN during checkout, and we will flash the module with the latest, most up-to-date GM factory calibrations specific to your exact build. This ensures a seamless installation and proper function right out of the box.
