Restore Your Vehicle’s Performance and Reliability
Is your Chevrolet Express, GMC Savana, or Silverado plagued by frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). For a work vehicle, downtime isn’t just an inconvenience—it’s lost income. This replacement PCM is the definitive, professional-grade solution to get your truck or van back on the road and running like new, without the exorbitant costs and delays of a dealership visit.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often leading to incorrect diagnoses and wasted money on other parts. If you’re experiencing any of the following, this module is your answer:
- Erratic engine performance or misfires
- Poor fuel economy
- Failure to pass emissions tests
- Automatic transmission shifting problems
- Diagnostic Trouble Codes (DTCs) such as P0601, P0602, P0606, or other communication errors
- Intermittent or total loss of power
This isn’t just a replacement part; it’s a complete service. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash this module with the latest, most stable software updates directly from GM. This ensures that when you receive your programmed 2007 Express 3500 PCM, it’s calibrated specifically for your vehicle’s engine, transmission, and options, restoring its original performance and efficiency.
An Expert’s Note: We recently helped a plumbing contractor whose 2006 Savana 3500 was dead in a customer’s driveway. The van would crank but never start, and he was losing a full day of work. The dealership quoted him over a thousand dollars and a week-long wait. We shipped him this VIN-programmed module overnight. After a straightforward installation and a simple security relearn, his van fired right up. He was back on the job the next morning, having saved hundreds of dollars and minimized his business losses. That’s the difference a reliable, ready-to-install part makes.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your vehicle.
Is any additional programming required after installation?
In most GM vehicles of this era, you will need to perform a security relearn procedure (often called a CASE relearn or Passlock relearn). This process syncs the new PCM with your vehicle’s anti-theft system and can typically be done in your driveway in about 30 minutes without any special tools. Instructions are widely available online for your specific model.
Will this fix my specific check engine light codes?
This module is a direct solution for internal PCM failure codes, such as P0601 (Internal Control Module Memory Check Sum Error). It can also resolve a wide range of other codes if the root cause is a faulty computer. However, you should always ensure other potential issues (e.g., wiring, sensors) have been ruled out for a complete diagnosis.
My original part number is 12589462. Will this work?
Yes. This PCM is a fully compatible replacement for several part numbers, including 12589462, 12602801, and 89017749. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
Where is the PCM located on my vehicle?
On most GM vans like the Express and Savana, the PCM is located in the engine compartment on the driver’s side. On trucks like the Silverado and Sierra, it is typically found under the battery tray on the driver’s side front of the engine bay. Always disconnect the battery before attempting removal or installation.
