An Expert’s Note on Programming
In a modern work truck or van, the PCM is more than just an engine computer—it’s the central command center. It manages everything from fuel injection timing and spark advance to transmission shift points and torque converter lockup. When we program your module, we’re not just copying old data; we’re installing the latest, most refined operating system from GM. This ensures all components work in harmony, which is especially critical for vehicles that tow heavy loads or see constant use. It’s the key to restoring not just function, but long-term durability.
Take control of your repair. By ordering this pre-programmed 2005-2007 Express 3500 PCM, you are choosing the smartest, most efficient path to getting your vehicle running right. It’s the professional-grade solution for the serious owner.
Frequently Asked Questions
Do I need to do anything after installation?
In many cases, the module is plug-and-play. However, some GM vehicles require a security relearn procedure (often called Passlock or Passkey) and a Crankshaft Variation Relearn (CASE). These procedures can typically be performed with a capable scan tool or by following a specific sequence of key cycles found in your service manual.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for service numbers 12589462, 12602801, and 89017749. If your original module has one of these numbers, this part will work for you.
What if my original PCM part number isn’t listed?
Please contact us with your VIN and original part number before ordering. We can verify compatibility to ensure you receive the correct part for your specific vehicle configuration.
Why is programming to my VIN so important?
Programming the PCM with your VIN ensures it has the correct software and calibrations for your vehicle’s specific engine, transmission, emissions equipment, and other options. An incorrectly programmed module can cause performance issues, check engine lights, or even prevent the vehicle from starting.
