Restore Peak Performance to Your GM Truck or SUV
Is your Silverado, Escalade, Sierra, or Tahoe suffering from baffling issues like stalling, erratic shifting, or a persistent check engine light? The Powertrain Control Module (PCM), the central computer of your vehicle, is often the culprit. This direct-fit replacement PCM, part number 28042802, is the definitive solution to restore your vehicle’s factory performance and reliability. We take the guesswork and high dealership costs out of the equation by pre-programming the module to your vehicle’s specific VIN with the latest GM software updates before it ships. This ensures a seamless installation process and optimal function right out of the box.
From the Diagnostic Bay
We had a 2005 GMC Sierra in the shop that was driving the owner crazy. It would randomly stall at stoplights, but never consistently, and it wouldn’t store any diagnostic trouble codes. The owner had already replaced the fuel pump and a handful of sensors with no luck. After hours of diagnostics, we hooked up a scope and monitored the PCM’s internal voltage regulators. We found that one of the processors was dropping voltage intermittently when it got warm. It was a classic case of a failing PCM that was difficult to pinpoint. We installed a VIN-programmed module just like this one, and the truck has been running perfectly ever since. Sometimes, the most complex problems have a straightforward solution.
Is Your Vehicle Exhibiting These Symptoms?
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your engine computer may need replacement:
- ✔ Persistent Check Engine Light (CEL) that won’t clear
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Harsh or erratic automatic transmission shifting
- ✔ A complete no-start condition where the engine cranks but won’t fire
- ✔ Poor fuel economy and decreased engine power
- ✔ Communication errors with diagnostic scan tools
- ✔ Unexplained warning lights on the instrument cluster
The Superior Solution: A Pre-Programmed 2003-2007 GM PCM
Replacing the brain of your vehicle can be intimidating, but our process makes it simple. Ordering a generic module online or from a parts store leaves you with a useless box that still needs an expensive trip to the dealership for programming. Our service handles the critical software flashing for you. By providing your VIN at checkout, you receive a 2003-2007 GM PCM that is loaded with the correct calibration files and the newest software revisions from General Motors. This not only fixes existing bugs but can also improve transmission shift points, fuel efficiency, and overall engine operation. This module is a direct replacement for multiple service numbers, including 89017750, 12582605, 12589463, and 12602802, ensuring wide compatibility across the GM truck and SUV lineup.
Installation is typically straightforward. In most cases, you simply disconnect the battery, unbolt the old PCM, plug in the new one, and reconnect the battery. Some vehicles may require a simple security relearn procedure, which can be done in your driveway without any special tools. This plug-and-play approach saves you time, money, and the hassle of scheduling a dealer appointment.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This PCM comes fully programmed to your vehicle’s VIN with the latest GM software updates. It is ready for installation right out of the box.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is crucial for us to load the correct software for your specific engine, transmission, and options.
Is this a simple plug-and-play installation?
Yes, for most vehicles it is. You disconnect the battery, swap the modules, and reconnect the battery. Some models may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Instructions are readily available online for this simple process.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM, then yes, this part will resolve the issue. However, if the light is on due to a faulty sensor or other component, you will still need to address that separate issue.
How do I know if this part fits my vehicle?
This part fits a wide range of 2003-2007 GM trucks and SUVs. Please review the detailed fitment list on this page or match one of the compatible service numbers (e.g., 89017750, 12582605, 12589463, 12602802) to your original part.
