An Expert’s Insight on These GM Computers
As a technician, I’ve seen countless of these late-90s GM trucks and vans come into the shop with bizarre, intermittent electrical gremlins. The culprit is often the original PCM. After years of heat cycles under the hood and constant vibration, the internal connections can become weak, causing issues that come and go. Drivers chase symptoms for weeks, replacing sensors and wiring, only to find the problem remains. A quality, tested, and properly programmed 16250279 PCM is the most efficient way to solve these frustrating issues for good and restore the rock-solid reliability these vehicles are known for.
Frequently Asked Questions
Is this a truly plug-and-play installation?
Yes, for the most part. Because this PCM is programmed to your VIN, it will have the correct software for your engine, transmission, and options. However, on GM vehicles of this era, you will need to perform a simple security relearn procedure after installation, which takes about 30 minutes and requires only the vehicle’s key. This procedure pairs the new computer to your vehicle’s anti-theft system. Instructions are readily available online or we can point you to them.
How do I provide you with my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot program and ship the computer without your VIN.
What happens if I don’t do the security relearn?
If the security relearn procedure is not performed, the vehicle’s anti-theft system will activate, and the engine will not start. This is a normal security feature.
Is this computer a new part?
No, this is a thoroughly tested, genuine OEM computer that has been sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution.
Will this fix my transmission shifting problems?
The PCM is responsible for controlling the transmission’s shift points and behavior. If your shifting issues are caused by a faulty computer, this part will resolve them. However, it will not fix mechanical problems within the transmission itself, such as worn clutches or a bad valve body.
How can I be sure this fits my vehicle?
Please review the detailed fitment list provided on this page. The most reliable way to ensure a match is to verify that your original computer’s part number is listed. If you are uncertain, please contact us with your VIN before ordering, and we will be happy to confirm compatibility for you.
