Restore Your Vehicle’s Brainpower and Performance
Is your Corvette, Camaro, or GM truck suffering from baffling electrical issues, poor engine performance, or a persistent Check Engine Light? The Powertrain Control Module (PCM), often called the Engine Control Module (ECM), is the central computer responsible for managing your engine, transmission, and dozens of other critical systems. When it fails, it can cause a cascade of problems that are difficult to diagnose and can leave your vehicle unreliable or completely inoperable. This direct-fit replacement PCM, part number 19109040, is the definitive solution to restore your vehicle’s factory performance and reliability.
This isn’t just a generic, off-the-shelf part. We take the guesswork and hassle out of the replacement process. Before we ship your module, our technicians will program it with the latest official GM software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at checkout. This ensures that when the part arrives, it’s a true plug-and-play solution, calibrated precisely for your engine, transmission, and emissions equipment. This critical programming step prevents compatibility issues and ensures all systems communicate correctly, just as the manufacturer intended.
From the Diagnostic Bay
We had a 2000 Silverado 2500 come into the shop with a complaint that stumped two other mechanics. The owner described a bizarre, intermittent issue where the transmission would randomly refuse to shift out of second gear, but only after driving for 20-30 minutes. There were no consistent trouble codes, just a generic communication error that would pop up and disappear. We checked the wiring, tested the solenoids, and even swapped the valve body. Nothing worked. On a hunch, we monitored the PCM’s data stream and noticed the output signals to the transmission solenoids would become erratic as the module heated up. We installed one of our VIN-programmed PCMs, performed the security relearn, and the truck has been shifting perfectly ever since. It’s a classic example of how a failing PCM can mimic a mechanical failure, and why a quality, correctly programmed replacement is non-negotiable.
Is Your Vehicle Exhibiting These Symptoms?
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer could be the culprit:
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Seemingly unrelated electrical components acting erratically.
The Importance of a VIN-Programmed Corvette Powertrain Control Module
In modern vehicles, the PCM is the heart of the onboard diagnostic and control network. It’s not a one-size-fits-all component. Your vehicle’s VIN is linked to specific calibrations for fuel delivery, ignition timing, transmission shift points, and emissions controls. Installing a non-programmed or incorrectly programmed module can lead to immediate running issues, warning lights, and even damage to other components. Our process eliminates these risks. By providing your VIN, you are guaranteed to receive a Corvette Powertrain Control Module that is perfectly matched to your vehicle’s original specifications, complete with any performance and reliability improvements released by GM since your vehicle was built.
Broad Compatibility Beyond the Corvette

Frequently Asked Questions
Do I need to do any programming after I receive the module?
No. We handle all the primary programming based on the VIN you provide. This loads the correct software and calibrations for your specific vehicle. However, on most GM vehicles of this era, you will need to perform a simple security relearn procedure (often called a Passlock or VATS relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure typically takes 10-30 minutes and can be done without any special tools. We can provide instructions for this process.
Where do I provide my VIN?
Please enter your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout. You can also reply to your order confirmation email with the VIN. We cannot program and ship your part without it.
Is this a plug-and-play installation?
Yes, after the security relearn procedure is completed. The physical installation is straightforward: disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Once the security relearn is done, the vehicle will start and run correctly.
What if my original part number is 09354896?
This module, 19109040, is the correct and updated service replacement for original part numbers 09354896 and 9354896. It is fully compatible and contains the most current software available from the manufacturer.
Will this fix my vehicle’s problem for sure?
While this PCM is the solution for a faulty engine computer, it’s essential to ensure the PCM is actually the root cause of your issue. Proper vehicle diagnostics are key. A PCM failure can mimic sensor or wiring problems. If you’re unsure, we recommend consulting with a qualified automotive technician to confirm the diagnosis before ordering.
