Restore Peak Performance and Drive with Confidence Again
Is your Corvette, Camaro, or GM truck feeling off? A faulty Powertrain Control Module (PCM) can be the hidden culprit behind a host of frustrating issues, from a persistent check engine light to poor fuel economy and unpredictable stalling. It’s the brain of your vehicle, and when it struggles, the entire system suffers. This isn’t just an inconvenience; it’s a loss of the reliability and performance you depend on. We’re here to provide the definitive solution—a high-quality, vehicle-specific PCM that restores your car’s heart and your peace of mind.

An Expert’s Note on “Ghost” Problems
“I once worked with a customer on his 2000 Silverado who had spent six months and a small fortune replacing sensors, plugs, and wires trying to fix a random misfire and stalling issue. No one could pinpoint the cause. When we finally tested the PCM, we found it was failing intermittently, especially when hot. Swapping in a correctly programmed module solved every single problem in one afternoon. He went from total frustration to pure relief. Sometimes, the simplest solution is the right one.”
Your Guided Path to a Successful Installation
Replacing the brain of your vehicle sounds intimidating, but it’s a straightforward process. Follow these steps for a confident, successful repair that gets you back on the road fast.
- Safety First: Begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On a 1999-2000 Corvette, you’ll find the PCM in the engine compartment on the right-hand (passenger) side. For trucks like the Silverado or Sierra, it’s typically under the hood on the driver’s side, below or near the battery tray.
- Disconnect the Harnesses: Carefully unclip and disconnect all electrical wiring harnesses from the old PCM. These connectors have locking tabs that need to be released before they can be pulled away. Avoid forcing them.
- Remove the Old Unit: Unbolt the old module from its mounting bracket and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed PCM securely onto the bracket. Reconnect all wiring harnesses, ensuring each one clicks firmly into place.
- Final Steps: Reconnect your battery’s negative terminal. In many GM vehicles, you may need to perform a simple security relearn procedure, which can often be done without special tools (instructions are widely available online or in service manuals). This syncs the new PCM with your vehicle’s anti-theft system.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you can add your VIN to the order notes or simply reply to your order confirmation email. We will not ship the part until we have your VIN to ensure a perfect match for your vehicle.
Will this 1999-2000 Corvette PCM fix my check engine light?
If your check engine light is caused by an internal module failure (indicated by codes like P0601, P0602, P0606), then this part is the correct solution. It will not fix issues related to other faulty sensors or mechanical problems on the vehicle.
Do I need to do anything after installing the module?
In most cases, you will need to perform a security relearn procedure, also known as a VATS relearn. This is a simple process that syncs the new module to your keys and typically takes about 30 minutes with no special tools required. Some truck applications may also benefit from a crankshaft position sensor variation relearn, which requires a scan tool.
Is this a brand new part from the dealer?
This is a genuine, original equipment part that has been meticulously inspected and tested to meet or exceed factory specifications. It is then loaded with the latest GM-certified software for your specific vehicle, ensuring flawless performance and longevity.
What makes your programming service special?
We use official GM equipment and software to flash the module with the most current updates available for your VIN. This corrects common factory drivability issues and ensures optimal communication between all of your vehicle’s systems, from the engine to the transmission and anti-lock brakes.
