Expert Insight: The Brains of Your Operation
On these late-90s GM vehicles, the PCM is more than just an engine controller; it’s the central command for the entire powertrain. It manages everything from the fuel injectors and ignition timing on your Vortec engine to the critical shift points in your 4L60E or 4L80E automatic transmission. When you receive a correctly flashed Programmed 09355699 PCM, you’re not just fixing a single problem—you’re restoring the precise, factory-intended communication between all these vital components. This is the key to a smooth idle, crisp throttle response, and reliable transmission performance that you can count on every day.
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. Our technicians will then use this VIN to flash the computer with the exact GM calibration file for your specific make, model, and options before we ship it to you.
Will I need to do anything after installing it?
In most cases, you will need to perform a simple security relearn procedure, also known as the Passlock or VTD relearn. This procedure does not require any special tools and typically involves turning the key on for 10-12 minutes, three times in a row. This syncs the new PCM with your vehicle’s anti-theft system.
What if my original part number is different from 09355699?
This module is a direct replacement for several part numbers, including 16266645, 16250279, and 09366810, among others listed. As long as your vehicle is on the compatibility list and you provide a valid VIN, we will ensure it is programmed correctly to function perfectly in your vehicle.
Is this a used part?
Yes, this is a thoroughly tested and inspected computer that was sourced from a salvaged vehicle. This allows us to provide a reliable and affordable OEM solution for your repair needs.
What causes a PCM to fail?
PCM failure can be caused by a number of factors, including electrical shorts in other components, voltage spikes from a faulty alternator or jump-start, excessive heat, vibration over many years, or water intrusion into the module housing.
