Is Your Vehicle Running Rough, Stalling, or Throwing Confusing Codes?
A failing Powertrain Control Module (PCM) can be the hidden cause of countless frustrating issues, turning your reliable daily driver into a source of constant stress. If you’re experiencing erratic engine behavior, poor fuel economy, or a persistent check engine light that mechanics can’t seem to solve, you’ve come to the right place. This isn’t just a replacement part; it’s the brain of your vehicle’s operation, fully restored and programmed specifically for you. We provide a straightforward solution to get your car back on the road, running as smoothly as it should.
Common Symptoms of a Failing PCM & Your Solution
A faulty PCM can manifest in various ways, often mimicking other sensor failures. Before you continue replacing parts hoping for a fix, see if these symptoms sound familiar:
- Persistent Check Engine Light (CEL) with multiple, unrelated trouble codes.
- Engine stalling, sputtering, or refusing to start.
- Harsh or erratic automatic transmission shifting.
- Noticeable decrease in fuel efficiency.
- Failure to communicate with diagnostic scan tools.
- Intermittent issues that seem to have no clear cause.
This professionally programmed PCM is the definitive solution. We take a quality, inspected module and flash it with the latest GM software updates, tailored precisely to your vehicle’s Vehicle Identification Number (VIN). This process ensures all factory parameters are correct, eliminating the guesswork and the need for expensive dealership programming. This is the most reliable way to fix the core problem and restore your vehicle’s performance.

An Expert’s Note on GM Anti-Theft Systems
“As a technician with over 20 years of experience, I’ve seen countless DIYers get stuck after installing a used computer from a salvage yard. What they often don’t realize is that on these late-90s GM vehicles, the PCM is tied directly to the Vehicle Anti-Theft System (VATS/Passlock). A mismatched module will prevent the fuel injectors from firing, and the car will not start. Our VIN programming service correctly configures the module to communicate with your car’s existing security system. After installation, you’ll perform a simple key-cycle ‘relearn’ procedureโno special tools neededโand the car will accept the new module. This is the critical step that makes our product a true plug-and-play solution, saving you from a tow to the dealer.”

Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will receive an email with instructions on where to send your 17-digit VIN. We cannot program and ship your module until we receive this information.
Is this part difficult to install?
Physically, the PCM is typically easy to access and replace with basic hand tools. After installation, you must perform a simple security relearn procedure which involves a series of key cycles. We provide instructions for this process, and no special tools are required.
Will this fix my specific problem?
This PCM will correct any issues directly caused by a faulty computer. While it solves a wide range of problems, we always recommend a proper diagnosis by a qualified mechanic to ensure the PCM is the root cause and not a separate sensor or wiring issue.
What is the security relearn procedure?
The security relearn procedure syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this cycle three times. This allows the components to communicate and authorize the new module. Detailed instructions are included with your order.
Does this PCM come with keys?
No, this listing is for the Powertrain Control Module only. Our programming service allows it to work with your existing keys after the security relearn procedure is completed.
How does the warranty work?
This unit is backed by our one-year replacement warranty. If the module fails within one year of the purchase date, we will provide a replacement unit. Please contact us for details on the warranty process.
