Restore Your Vehicle’s Performance and Reliability
Is your late-90s GM vehicle suffering from frustrating engine issues like stalling, poor fuel economy, erratic shifting, or a persistent Check Engine Light? A failing Powertrain Control Module (PCM) is often the culprit, acting like a faulty brain for your engine. This replacement PCM is the definitive, hassle-free solution to get your car running like it should. We take the guesswork out of the repair by pre-programming this unit to your car’s specific Vehicle Identification Number (VIN) before it ever leaves our facility. This ensures a seamless installation and restores the communication between all your vehicle’s critical systems.

Expert Insight: The Critical Role of VIN Programming
Many people don’t realize that a PCM isn’t just a part you can swap from another car. For these late-90s GM vehicles, the module must be programmed with the vehicle’s unique Vehicle Identification Number (VIN) to communicate with the anti-theft system (PassLock/VATS) and other onboard modules. Skipping this critical step is a recipe for a no-start condition. We handle this programming for you with our Programmed 9357034 PCM, saving you time, money, and the headache of a car that won’t run after the repair.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the part to function in your car.
Is this a ‘plug-and-play’ part?
Yes. Because we program the module to your VIN before shipping, it is ready for installation upon arrival. In most cases, no further programming is required. However, some vehicles may require a simple security relearn procedure, which can be done without special tools and instructions can be easily found online.
What if my original part number is different from 9357034?
This module is a direct replacement for several service numbers, including 09356741, 16236757, 9357440, and 9366314. Please check the fitment list on this page to confirm compatibility with your specific make, model, and year.
Will this fix my specific Check Engine Light code?
This PCM is the direct solution for codes related to module failure, such as internal processor errors or communication faults (typically in the P06xx range). While it can also resolve issues that cause other codes (like misfires or fuel trim problems), it’s crucial to ensure other components like sensors or wiring have been checked to properly diagnose the root cause.
Do I need to send my old PCM (core) back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
