End the Frustration of a Failing Engine Computer
Is your late-90s GM vehicle suffering from baffling electrical gremlins, a persistent check engine light, or performance issues you just can’t seem to trace? A failing Powertrain Control Module (PCM) is often the culprit, acting as the brain of your vehicle and controlling everything from fuel mixture to transmission shift points. When it falters, it can cause a cascade of problems that leave you stranded and frustrated. This is the direct, reliable solution to get your car back on the road and running the way it was designed to, restoring both performance and your confidence in your vehicle.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty PCM is the likely cause. This pre-programmed unit is designed to be the definitive fix for these exact issues:
- Persistent Check Engine Light (CEL) with communication-related codes (U-codes)
- Engine stalling or shutting off unexpectedly while driving
- Harsh or erratic automatic transmission shifting
- Complete no-start condition where the engine cranks but won’t fire
- Noticeable decrease in fuel economy
- Failure to pass an emissions test
By ordering this programmed 9357440 PCM, you’re not just buying a part; you’re getting a plug-and-play solution. We flash the module with the latest official GM software updates, tailored specifically to your car’s Vehicle Identification Number (VIN).

Expert Insight: The Importance of VIN Flashing
In vehicles from this era, the PCM is the heart of the anti-theft system (GM’s Passlock or Passkey). Simply swapping in a used module from another car will trigger the security system and prevent the engine from starting. That’s why our VIN programming service is not just a convenience—it’s essential. We link this programmed 9357440 PCM to your car’s identity before it ever leaves our facility. This ensures that when you install it, the vehicle recognizes it as a legitimate component, allowing for a smooth installation process and saving you a costly trip to the dealer for programming.
Don’t let a faulty computer keep your reliable GM vehicle off the road. This is your opportunity to fix the problem correctly the first time. After you complete your purchase, we will reach out to obtain your VIN. Once we have it, our technicians will program the module, and we will ship it directly to you, ready for installation.
Frequently Asked Questions
Do I need to do anything after installing this PCM?
Yes. While the main programming is done for you, you will need to perform a simple security relearn procedure. This can typically be done without any special tools and involves a sequence of key turns. This syncs the module to your vehicle’s anti-theft system. Instructions are readily available online for your specific model.
How do I provide my vehicle’s VIN?
After you place your order, we will contact you via email to request your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to perform the necessary programming.
Is this the correct part for my car?
This module replaces service numbers 09356741, 16236757, 9356741, 9357034, 9357440, and 9366314. Please check the part number on your original module and consult the detailed fitment list on this page to ensure compatibility with your specific make, model, and engine.
What happens if I install a PCM that isn’t programmed?
An unprogrammed PCM will not work. Your vehicle’s anti-theft system will activate, and the engine will not start. Our service eliminates this problem by pre-programming the unit to your car’s VIN.
What tools are needed for installation?
Installation typically requires only basic hand tools, such as a socket set and a screwdriver, to access and replace the module. The most important first step is to disconnect the negative terminal of your vehicle’s battery.
