An Expert’s Note on These GM Computers
As a technician, I’ve seen countless issues with these late-90s GM vehicles. The PCM, often called the ‘black box,’ is the heart of the entire powertrain. It doesn’t just manage the engine; it’s responsible for the precise control of the 4L60E or 4L80E automatic transmission. When it fails, you get more than just an engine code—you get a vehicle that’s unreliable and unsafe to drive. A properly VIN-matched Programmed 9355699 PCM is the only way to ensure all systems, especially the transmission, function exactly as the factory intended.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians then use this VIN to load the latest GM-certified software and calibrations directly onto the PCM. This ensures it matches your vehicle’s specific engine, transmission, and options perfectly.
Is this a new part?
No, this is a high-quality, tested computer that was sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution for keeping these classic trucks and vans on the road.
Will I need to do anything after I install it?
In most cases, this is a plug-and-play installation. However, depending on your specific vehicle, a simple security relearn procedure (often called Passlock or VATS) may be required. This can typically be done without special tools and instructions are widely available online.
How can I be sure my PCM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have a qualified mechanic diagnose the issue. Common diagnostic trouble codes (DTCs) pointing to a bad PCM include P0601, P0602, P0604, and P0606. Also, ensure your battery, grounds, and wiring are in good condition before replacing the computer.
Which vehicles does this part fit?
This PCM fits a very wide range of 1998 and 1999 General Motors trucks, vans, and SUVs equipped with gasoline engines, including the Chevrolet Express, GMC Savana, Chevrolet/GMC Pickups (1500, 2500, 3500), Suburban, Tahoe, Yukon, Cadillac Escalade, and more. Always confirm your original part number is 9355699 or one of its interchanges.
What is the warranty on this computer?
This unit is backed by our one-year replacement warranty. This provides coverage and confidence in your purchase.
