Restore Peak Performance to Your GM Vehicle
Is your GMC Savana, Chevy Express, or Silverado suffering from erratic behavior, poor fuel economy, or a persistent Check Engine Light? The Powertrain Control Module (PCM), often called the engine’s brain, is the central command unit for your vehicle’s engine and transmission. When it fails, it can cause a cascade of frustrating and performance-robbing issues. This direct-fit replacement PCM, part number 12602801, is the definitive solution for a wide range of GM trucks and vans, ensuring your vehicle runs exactly as the manufacturer intended.
From the Diagnostic Bay
We had a 2006 Silverado 2500 with the 8.1L engine come in with a complaint of intermittent stalling and harsh shifting. The owner had already replaced the throttle body and a few sensors with no luck. Scans showed a handful of inconsistent communication codes. Instead of continuing to chase ghosts, we focused on the central hub: the PCM. After installing one of our VIN-programmed modules, the communication codes vanished, the transmission shifted smoothly, and the stalling issue was completely resolved. It’s a powerful reminder that sometimes the core component is the simplest fix.
Is Your Vehicle Showing Signs of a Failing PCM?
A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, a failing engine computer could be the culprit:
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Unexplained drops in fuel efficiency.
- ✔ Rough or unstable idling.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Hard starting or no-start conditions.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass emissions testing.

Frequently Asked Questions
Do I need to have this PCM programmed?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software and your vehicle’s specific calibration.
Is this a simple plug-and-play installation?
Yes, for the most part. Once you receive the VIN-programmed module, you just need to install it. In some cases, your vehicle may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for this simple process.
What information do you need from me?
All we need is your vehicle’s 17-digit VIN. This allows us to access the correct GM calibration files to ensure the PCM works perfectly with your engine, transmission, and factory options.
Will this fix my Check Engine Light?
If the Check Engine Light and associated diagnostic trouble codes (DTCs) are being caused by a faulty PCM, then this replacement part will resolve the issue. It is always best to have a proper diagnosis performed to confirm the PCM is the point of failure.
Is this compatible with other part numbers?
Yes, this module, 12602801, is a direct, compatible replacement for part numbers 12589462 and 89017749, covering a wide range of GM vehicles.
