Is Your GM Truck or Van Sidelined? Get It Back on the Road.
Is your reliable workhorse suddenly running rough, shifting poorly, or refusing to start? A persistent Check Engine Light and confusing diagnostic codes can point to a failing Powertrain Control Module (PCM), the brain of your vehicle’s engine. When the PCM falters, it can bring your business or daily routine to a grinding halt. This isn’t just an inconvenience; it’s lost time and money. You need a solution that is fast, reliable, and doesn’t require a costly trip to the dealership.
Common Symptoms & Your Direct-Fit Solution
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty module is a likely culprit:
- Poor or erratic automatic transmission shifting
- Unexplained drop in fuel economy
- Engine stalling, stumbling, or rough idling
- Complete no-start condition where the engine cranks but won’t fire
- Check Engine Light with communication error codes (like P0601, P0605)
This programmed 1999-2002 Savana 2500 PCM is the definitive solution. We take all the guesswork and hassle out of the repair. Before we ship it, we flash the module with the latest official GM software updates, tailored specifically to your vehicle’s unique Vehicle Identification Number (VIN). This ensures perfect compatibility and performance the moment you install it.

A Technician’s Tip: As a mechanic with over two decades of experience, I’ve seen people chase phantom electrical issues for weeks, replacing perfectly good sensors, only to find the PCM was the culprit all along. One critical step people often miss during installation is ensuring clean, tight ground connections. Before you plug in your new module, take five extra minutes to clean the battery terminals and the main chassis ground points. A solid ground is essential for the PCM to function correctly and will prevent a world of headaches down the road.
Don’t let a faulty computer keep your truck off the road. By providing us with your VIN at checkout, you’re not just buying a part; you’re buying a complete, hassle-free solution. This is the most efficient and cost-effective way to restore your vehicle’s performance and dependability. With a correctly functioning brain, your engine and transmission can once again work in perfect harmony. Order your programmed 1999-2002 Savana 2500 PCM today and get back to what’s important.
Frequently Asked Questions
Do I need to take this part to a dealer for programming?
Absolutely not. The main benefit of our service is that this module arrives at your door pre-programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, saving you time and the high cost of dealer programming.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you for your VIN. You can also add your 17-digit VIN to the ‘notes’ section during checkout to expedite the process.
My vehicle has a security system. Will this work?
Yes. If your vehicle is equipped with a security system like GM’s VATS or Passlock, you will need to perform a simple ‘relearn’ procedure after installation. This procedure can be done by anyone in about 10-15 minutes and does not require any special tools. We can provide instructions upon request.
Is the installation difficult?
For most DIYers with basic tools, the installation is very straightforward. It involves disconnecting the vehicle’s battery, locating and unplugging the old module, swapping it with the new one, and reconnecting the battery. It’s a true plug-and-play repair.
How can I be sure my old PCM is the problem?
While only a full diagnostic can be 100% certain, common indicators of a failing PCM include multiple unrelated error codes, engine performance issues (like stalling or poor mileage) that don’t resolve after replacing sensors, and communication errors with scan tools. If you’ve checked other components and the problem persists, the PCM is the most likely cause.
