Is Your GM Truck or Van Plagued by Mysterious Issues?
Is your trusty GMC Safari, Chevy Express, or other GM workhorse suddenly running rough, stalling unexpectedly, or showing a persistent check engine light? A failing Powertrain Control Module (PCM) is often the hidden culprit behind these frustrating and hard-to-diagnose problems. It can affect everything from fuel economy and transmission shifting to whether the engine starts at all. This isn’t just an inconvenience; it’s a reliability issue that can cost you time and money. Instead of guessing with expensive sensors or parts, get to the heart of the problem with a reliable, correctly programmed engine computer.

- Failure to start or intermittent stalling

Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need the full 17-digit Vehicle Identification Number (VIN) from your vehicle. This is typically found on the driver’s side dashboard (visible through the windshield) or on the door jamb sticker.
Is this part difficult to install?
Physically, the PCM is usually easy to replace, requiring only basic hand tools. It’s typically located in the engine compartment. After installation, you will need to perform a security relearn procedure (often called a CASE relearn) which can be done without special tools. Instructions can be readily found online for your specific model.
Is this a new part?
No, this is a high-quality, used OEM computer that has been carefully removed from a salvaged vehicle. We test the hardware to ensure it is fully functional before programming it for you.
Will this fix my specific problem?
This module will correct issues directly caused by a failing PCM. While it solves the vast majority of electronic running problems, it’s essential to ensure your vehicle’s wiring and sensors are in good condition. A proper diagnosis is always recommended.
How long does the programming and shipping process take?
Once we receive your VIN, programming is typically completed within one business day. The unit is then shipped out, and you will receive tracking information to follow its progress.
