Restore Your Truck’s Brain, Restore Your Confidence
Is your Chevrolet or GMC truck or van acting possessed? Stalling at intersections, shifting erratically, or refusing to start for no reason? A failing Powertrain Control Module (PCM) can turn your reliable workhorse into a source of constant frustration. This isn’t just an inconvenience; it’s lost time, lost jobs, and lost confidence in your vehicle. It’s time to stop guessing and install the definitive solution. This module is the central command for your engine and transmission, and we deliver it to you fully programmed and ready to get you back on the road.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty PCM is the most likely culprit. This module is the proven fix for:
- Harsh or unpredictable transmission shifting
- Poor fuel economy and loss of power
- Engine stalling, stumbling, or a rough idle
- A persistent Check Engine Light that won’t go away
- No-start conditions where the engine cranks but won’t fire
- Diagnostic Trouble Codes (DTCs) such as P0601, P0604, or P0606
By installing our precisely programmed 1999-2002 Express 2500 PCM, you are directly addressing the root cause of these issues and restoring your vehicle’s factory-specified performance and reliability.

Expert Insight from the Garage
I’ve seen countless technicians and DIYers chase their tails for weeks, replacing sensors and wiring, only to find the PCM was the problem all along. The computer is the ‘brain,’ and when it gets confused, it sends bad signals everywhere. The biggest hurdle used to be programming a replacement. You’d buy a used one from a junkyard, install it, and the truck still wouldn’t start because the security system didn’t recognize it. Our process takes that entire headache away. By sending you a 1999-2002 Express 2500 PCM that’s already programmed to your truck’s identity, we turn a complex, multi-step repair into a simple component swap. It’s the smartest, most efficient way to get your rig back to work.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive and validate this information, as the programming is specific to your vehicle.
Is this a simple plug-and-play installation?
Yes, the hardware installation is a direct swap. After installing the module, you will need to perform a security relearn procedure (often called a ‘key relearn’ or ‘passlock relearn’). This process is straightforward, takes about 30 minutes, and does not require any special tools. We can provide instructions for this procedure.
Will this fix my specific check engine light codes?
This PCM is a direct solution for internal module failure codes like P0601 (Internal Control Module Memory Check Sum Error). It can also resolve a wide range of other codes caused by faulty module logic. However, you should always ensure other components, like sensors and wiring, are in good condition.
Do I need to send my old part back?
No core charge is required for this part. You do not need to return your old, faulty module to us.
What if I have questions during installation?
Our team of experienced technicians is here to help. If you encounter any issues or have questions about the installation or security relearn process, you can contact our customer support for assistance.
