A Veteran Technician’s Insight: The PCMs from this GM era are known for specific internal failures, often related to heat cycles causing solder joints to crack or internal capacitors to fail over 20+ years of service. This isn’t just a random failure; it’s a common wear item. When these components degrade, they send incorrect signals, leading to the erratic behavior you’re likely seeing. Installing a properly prepared 1998 Oldsmobile Silhouette PCM isn’t just a patch; it’s a foundational repair that ensures your engine and transmission are getting the correct commands for reliable, long-term operation.
