Restore Your Minivan’s Performance and Reliability
Is your 1998 Oldsmobile Silhouette suffering from frustrating issues like stalling, erratic shifting, or a persistent check engine light? A failing Powertrain Control Module (PCM) is often the culprit, acting as the vehicle’s brain and controlling everything from fuel mixture to transmission behavior. This isn’t just an inconvenience; it’s a matter of reliability for your family’s transportation. We offer a direct, dependable solution: a replacement PCM, professionally programmed to your vehicle’s specific VIN, ready for installation right out of the box.

An Expert’s Note: Don’t Chase Ghosts in the Machine
As a technician, I’ve seen countless hours and dollars wasted on replacing perfectly good sensors and solenoids because of a faulty PCM. A failing module can send out false error codes, leading you on a wild goose chase. For example, a customer with a 1998 Venture (which uses the same PCM) was about to pay for a transmission rebuild due to harsh shifting. The real issue was the computer. Installing a properly programmed 1998 Oldsmobile Silhouette PCM 09356741 solved the problem instantly, saving them over a thousand dollars. Always consider the PCM when you have multiple, unrelated electronic issues.
Getting your minivan back to its reliable self is our priority. This isn’t just a part; it’s the key to restoring your vehicle’s performance and your peace of mind on the road. With our pre-programmed 1998 Oldsmobile Silhouette PCM 09356741, you’re choosing a straightforward, professional-grade repair.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives at your door fully programmed to your vehicle’s VIN. In most cases, it is a simple plug-and-play installation. However, some GM vehicles of this era may require a security relearn procedure (often called a CASE relearn or Passlock relearn), which can typically be done without special tools. Instructions for this are widely available online.
How do I provide my VIN?
After you complete your purchase, simply send us a message with 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.
Is this compatible with my 1998 Pontiac Grand Prix?
Yes, it is. This module fits a wide variety of 1998-1999 GM vehicles, including the Grand Prix, LeSabre, Lumina, Monte Carlo, Regal, Cutlass, Grand Am, and many others as listed in the compatibility chart. The key is to match one of the compatible service numbers.
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer that controls your vehicle’s engine and transmission. It takes in data from dozens of sensors and uses that information to manage fuel injection, ignition timing, emissions systems, and transmission shift points to ensure the vehicle runs efficiently and smoothly.
Where is the PCM located on my 1998 Oldsmobile Silhouette?
On the 1998 Oldsmobile Silhouette, as well as the Pontiac Trans Sport and Chevy Venture, the PCM is typically located in the LH (driver’s side) engine compartment, often housed within the air cleaner assembly for protection.
