Is Your Dependable GM Truck or SUV Suddenly Unreliable?
It’s frustrating when a vehicle you count on every day starts acting up. Stalling at intersections, refusing to start, or a persistent Check Engine Light can sideline your workhorse and disrupt your life. For many 1998-1999 GM vehicles, these problems point directly to a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the brain of your engine. Our pre-programmed replacement is the definitive solution to restore the performance and reliability you depend on.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a faulty PCM is the likely culprit. This module is the direct fix for:
- Engine stalling or random shutdowns
- Failure to start, even with a good battery and starter
- Poor fuel economy and rough idling
- Harsh or erratic automatic transmission shifting
- Check Engine Light (CEL) with communication error codes (DTCs like P0600-P0606)
- Apparent sensor failures even after replacing the sensors
Instead of wrestling with a trip to the dealer for expensive diagnostics and programming, we provide a simple, effective solution. This Programmed 09355699 PCM arrives at your door flashed with the latest official GM software updates, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). It’s designed to get you back on the road quickly and confidently.

- โ Plug-and-Play Potential: Designed for a straightforward installation, this module gets you closer to a running vehicle right out of the box. (Note: A security relearn procedure may be required on some models, which can be done without special tools.)
- โ Restored Drivability: By correcting engine and transmission control, this module restores smooth shifting, stable idling, and proper engine performance.
- โ Cost-Effective Repair: Avoid the high costs and scheduling hassles of a dealership service department with a solution you can install yourself or have your trusted mechanic handle.
- โ Peace of Mind Included: This unit is backed by our one-year replacement warranty.
An Expert’s Take: The GM trucks and vans from this era are legendary for their durability. The Vortec engines are workhorses that just keep going. However, after 20+ years of heat cycles and vibrations, the electronic components in the original PCM can begin to break down. Solder joints crack, capacitors fail, and processors can short out. A replacement isn’t just about fixing a problem; it’s about giving that legendary powertrain a reliable brain so it can serve you for many more years. This Programmed 09355699 PCM is the key to that longevity.
We’ve taken the complexity out of the process. Once you place your order, simply provide us with your VIN, and our technicians will handle the programming. We ensure that the Programmed 09355699 PCM you receive is the correct, updated unit for your specific truck, van, or SUV.
Frequently Asked Questions
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery, unplugging the electrical connectors from the old module, and unbolting it from the vehicle. The new module bolts in the same way. Some vehicles may require a simple security relearn procedure (often called a Passlock or VATS relearn) which can usually be done with just the ignition key and a few minutes of time.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an email with instructions, or you can simply reply to your order confirmation email with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Will this fix my specific problem or Check Engine Light code?
This PCM is a common solution for a wide range of engine performance issues and communication-related diagnostic trouble codes (DTCs). While it is the definitive fix for an internally failed module, we always recommend proper diagnostics to confirm the PCM is the root cause of your issue before ordering.
My original part number is different. Will this still work?
Yes. This module is a direct replacement for several part numbers, including 16250279, 09366810, and 09355699. As long as your vehicle is listed in the compatibility chart, we will program this module to function perfectly for your application.
What does the one-year replacement warranty cover?
This unit is backed by our one-year replacement warranty. This covers the module against failure or defects for one year from the date of purchase. If the unit fails within this period, we will provide a replacement part.
