An Expert’s Insight on PCM Programming
As a technician with over two decades of experience, I’ve seen countless drivers chase phantom issues, replacing sensors and spark plugs only to find the root problem was the PCM itself. For these late-90s GM vehicles, the software is just as critical as the hardware. A generic, unprogrammed module from a parts store simply won’t work. Our process ensures the module you receive is not just a compatible part, but the correct part for your exact car, loaded with software that accounts for its specific systems. This is the difference between a temporary fix and a lasting repair that gives you confidence every time you turn the key. The 1998 Buick Skylark PCM 9357440 you order from us is the right way to do the job.

By providing us with your VIN upon purchase, you ensure that the 1998 Buick Skylark PCM 9357440 we ship is perfectly matched and ready to restore your vehicle’s performance and dependability.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of the engine and transmission, such as fuel injection, spark timing, and shift points, to ensure optimal performance, fuel economy, and emissions.
How does the VIN programming process work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. We use this number to access the latest official GM software calibration for your specific make, model, and options. We then flash this software onto the module before shipping it to you.
Is any additional programming needed after I install it?
In most cases, no. Our goal is to provide a plug-and-play solution. Once installed, the module is ready to work. Some vehicles may require a simple security relearn procedure (often called a CASE relearn), which can typically be done without special tools. Instructions can be easily found online or in a repair manual.
How do I know if this part is compatible with my vehicle?
This module is compatible with a wide range of 1998-1999 GM vehicles. Please check the detailed fitment list on this page. The most important step is providing your VIN so we can ensure the programming is a perfect match for your car’s systems.
Is this a new or used part?
This is a high-quality, inspected, and tested replacement component that has been verified to meet or exceed original equipment performance standards. It is then programmed with fresh, updated software specific to your vehicle.
