Get Your Work Van Back on the Job, Fast.

When your GM workhorse—be it a Savana van, a Silverado pickup, or an Express—starts acting up, you’re not just dealing with a vehicle problem; you’re facing downtime that costs you money and peace of mind. A failing Powertrain Control Module (PCM) is often the hidden culprit behind a host of frustrating issues. This professionally programmed engine computer is the definitive, no-hassle solution to get your vehicle running reliably again, shipped directly to you and ready for installation.

Common Symptoms & Your Solution

If you’re experiencing any of the following, a faulty PCM is the likely cause. This module is the solution for:

  • Persistent Check Engine Light (CEL)
  • Diagnostic Trouble Codes (DTCs) related to the module, such as P0601, P0605, or P0606
  • Poor or erratic automatic transmission shifting
  • Reduced fuel economy
  • Engine stalling, stumbling, or rough idling
  • Failure to pass emissions testing
  • Intermittent no-start conditions

Instead of risking a generic, un-programmed unit or paying steep dealership prices, our 1999-2002 Savana 3500 PCM arrives programmed specifically for your vehicle. We use your Vehicle Identification Number (VIN) to flash the module with the latest GM software updates, ensuring all systems communicate perfectly, just as the factory intended.

Features & Tangible Benefits

  • ✔ VIN-Specific Programming: Your new PCM is a perfect digital match for your vehicle, ensuring seamless integration and resolving complex electronic issues.
  • ✔ Latest GM Software Updates: We flash the module with the newest factory software, which often corrects performance and drivability issues the original programming had.
  • ✔ Plug-and-Play Ready: This module arrives ready to be installed. In most cases, you can get your vehicle back on the road without needing a special scan tool for setup. (A simple security relearn may be required, which you can do yourself. See our FAQ).
  • ✔ Restored Engine Performance: By restoring correct fuel delivery, spark timing, and transmission control, you’ll regain the smooth and dependable performance you rely on.
  • ✔ Cost-Effective Solution: Get a fully functional, correctly programmed module without the high cost and scheduling headaches of a dealership visit.

An Expert’s Note on PCM Programming

As a technician with over 20 years on the floor, I can’t stress this enough: proper programming is everything. A PCM is the brain of your engine and transmission. We’ve seen countless vehicles with persistent mystery issues simply because a generic or improperly programmed module was installed. Our process ensures every parameter—from fuel trim and idle speed to transmission shift points—is set precisely to your vehicle’s VIN. This isn’t just a fix; it’s a restoration of your vehicle’s original operating intelligence, ensuring reliability for the long haul.

This module is the correct, reliable heart transplant your truck or van needs. By providing us with your VIN at checkout, you ensure that the 1999-2002 Savana 3500 PCM you receive is the exact one your vehicle requires to perform its best. Don’t let a faulty computer keep you off the road—get the right part, programmed correctly, and get back to work.

Frequently Asked Questions

Do I need to do anything after I install the module?

In most cases, you will need to perform a simple security relearn procedure, also known as a VATS relearn. This process syncs the new module with your vehicle’s anti-theft system and does not require any special tools. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating the cycle two more times. We include instructions to make this process easy.

How do I provide you with my VIN?

After you complete your purchase, you can send us your 17-digit VIN through the messaging system or add it as a note during checkout. We cannot program and ship your module without it, so please provide it promptly to avoid delays.

Is this a new part?

This is a quality-tested, expertly programmed original equipment module. Each unit undergoes rigorous inspection and testing to ensure it meets or exceeds factory specifications, providing you with a reliable and long-lasting solution.

Will this fix my check engine light?

If the check engine light is caused by a faulty PCM (e.g., internal processor error codes), this module will resolve the issue. However, if the light is on due to other failing sensors or components (like an oxygen sensor or EGR valve), those parts will still need to be addressed. This module ensures the vehicle’s ‘brain’ is functioning correctly.

What if my original part number doesn’t match exactly?

That’s the benefit of our service! As long as your vehicle’s year, make, and model are on our compatibility list, our VIN-specific programming ensures the module we send will be 100% compatible. The programming makes it the correct part for your truck or van, superseding multiple original part numbers.
