Restore Peak Performance to Your GM Truck or SUV
Is your Silverado, Sierra, Tahoe, or other GM vehicle suffering from perplexing engine issues? A faulty Powertrain Control Module (PCM) is often the culprit behind poor performance, erratic behavior, and frustrating check engine lights. As the central computer for your engine and transmission, its proper function is critical. This replacement PCM, service number 89017750, is the definitive solution to get your vehicle running like new again. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific VIN with the latest factory software from GM. This ensures seamless integration and optimal performance right out of the box.
From the Diagnostic Bay
We had a 2005 Silverado 1500 in the shop that was driving the owner crazy. It had a random, harsh 1-2 shift and an intermittent cylinder misfire that would come and go. The owner had already replaced spark plugs, wires, and even a transmission shift solenoid with no success. After hours of diagnostics, we found that the injector driver circuit within the original PCM was failing intermittently, causing the misfire, and the faulty processor was also corrupting transmission commands. We installed one of these VIN-programmed PCMs, performed the security relearn, and the truck ran perfectly. It solved two separate, frustrating problems with one correct part.
Common Symptoms of a Failing 2003-2007 GM PCM
If you’re experiencing any of the following issues, a failing PCM could be the root cause. This module is the brain behind your vehicle’s most critical systems, and its failure can manifest in numerous ways.
- ✔ Check Engine Light is on with PCM-related fault codes (e.g., P0601, P0606).
- ✔ Engine stalling, stumbling, or running rough for no apparent reason.
- ✔ Unexplained decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Vehicle cranks but refuses to start (no-start condition).
- ✔ Communication errors when trying to use a diagnostic scan tool.
- ✔ Intermittent loss of power or hesitation during acceleration.

Frequently Asked Questions
Do I need to have this PCM programmed by a dealer?
No. We handle all the programming for you before shipment. We use your vehicle’s VIN to load the correct GM factory software, making it ready for installation when you receive it.
What is the security relearn procedure?
After installation, you will likely need to perform a simple security relearn procedure so the module can recognize your vehicle’s anti-theft system and keys. This procedure typically takes 10-30 minutes and can be done without any special tools. Instructions are widely available online or in your vehicle’s service manual.
Where is the PCM located on my truck?
On most compatible GM trucks and SUVs from this era (like the Silverado, Sierra, and Tahoe), the PCM is located in the engine bay on the driver’s side, under the battery tray or near the airbox.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your part without it. You can typically find your VIN on your driver’s side door jamb sticker or on the dashboard visible through the windshield.
Will this part fix my specific problem?
This PCM will correct issues directly caused by a faulty module. While the symptoms listed are common indicators of PCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the PCM is the source of your problem before ordering.
