Restore Your Minivan’s Dependability and Performance
Is your 1999 Oldsmobile Silhouette running rough, stalling unexpectedly, or simply refusing to start? A failing Powertrain Control Module (PCM) is a common cause for these frustrating and stressful issues, leaving you without the reliable transportation you depend on. This genuine GM engine computer, part number 09361735, is the definitive solution to get your vehicle back on the road. We professionally program this module to your vehicle’s specific VIN, ensuring it arrives ready for a straightforward installation, restoring your minivan’s factory performance and your peace of mind.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, a failing computer is the likely culprit:
- Check Engine Light (CEL) Illumination: Often with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0605, or P0606.
- No-Start or Intermittent Stalling: The engine may crank but won’t start, or it may stall while driving.
- Poor Engine Performance: Noticeable loss of power, rough idling, hesitation, or decreased fuel economy.
- Erratic Transmission Shifting: Harsh or delayed shifts as the PCM struggles to communicate with the transmission controller.
- No Communication with Scan Tools: The diagnostic port may be unresponsive, making it impossible to pull codes.
This pre-programmed 1999 Oldsmobile Silhouette PCM is the direct solution to these issues, restoring the critical link between your vehicle’s engine, transmission, and other electronic systems.

An Expert’s Insight on VIN Programming
From over 20 years of hands-on diagnostics, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply swapping a used PCM from another car rarely works due to different calibrations and anti-theft systems. That’s why we insist on programming every single unit to your specific Vehicle Identification Number (VIN). This ensures all systems—from the engine and transmission to the anti-theft security—communicate correctly, just as the factory intended. It’s the critical step that separates a quick fix from a lasting, reliable repair for your 1999 Oldsmobile Silhouette PCM.
Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship the part without it, as the programming is essential for the computer to function in your car.
Is this part difficult to install?
The physical installation is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one. However, some vehicles may require a security relearn procedure after installation, which can typically be done without special tools. Instructions can be readily found online for your specific model.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the PCM (e.g., codes P0601-P0606), then this part is the correct fix. However, a check engine light can be caused by many other components. We always recommend a proper diagnosis to confirm the PCM is the point of failure before ordering.
Is this a new part?
No, this is a high-quality, used OEM (Original Equipment Manufacturer) part that has been sourced from a salvaged vehicle. Each unit is carefully inspected and tested to ensure it is fully functional before being programmed and shipped.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. ECU (Electronic Control Unit) is a generic term. ECM (Engine Control Module) specifically controls engine functions. PCM (Powertrain Control Module) is the most common term for modern vehicles, as it controls both the engine and the transmission functions in one integrated unit.
