An Expert’s Note on Programming
Over my 20 years under the hood, I’ve seen countless DIYers install a junkyard computer only to find the car won’t start or runs worse than before. That’s because the PCM is the brain, and it needs to be matched to your car’s specific DNAโthe VIN. Our programming service isn’t just a convenience; it’s the critical step that ensures your vehicle’s anti-theft system, transmission, and engine parameters all work together in perfect harmony, just as the factory intended. This is the difference between a quick fix and the right fix.
Don’t let a faulty computer keep you off the road. By ordering this Programmed 09356741 PCM, you are choosing a reliable, professionally prepared component that will restore your confidence in your vehicle. Simply provide your VIN at checkout, and we’ll handle the rest.
Frequently Asked Questions
What exactly does a PCM do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission function, including fuel injection, spark timing, emissions systems, and shift points, to ensure optimal performance, efficiency, and low emissions.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your car.
Will I need to do any extra programming after I install it?
No, this unit is shipped fully programmed and ready for installation. In some GM vehicles, a simple, non-scan tool procedure called a Security Relearn or Case Relearn may be required after installation. This can typically be done in your driveway and instructions are widely available.
How can I be sure this part fits my vehicle?
This module replaces service numbers 09356741, 16236757, 9357034, 9357440, and 9366314. The best way to ensure perfect compatibility is to match one of these numbers from your original part and provide us with your VIN during checkout. We use the VIN to confirm the exact fitment and apply the correct software.
Where is the PCM located on my car?
On most of these late-90s GM models, the PCM is located in the engine compartment, often inside the air filter box assembly for protection and cooling. On some models, it may be located under the dashboard on the passenger side.
What happens if I have a problem after installation?
Your purchase is protected. This unit is backed by our one-year replacement warranty. If you encounter any issues with the module itself, please contact us, and we will be happy to assist you with the replacement process.
