Is Your GM Truck or SUV Showing Its Age?
If you’re dealing with a persistent check engine light, erratic shifting, stalling, or poor fuel economy in your late-90s GM vehicle, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an annoyance; it’s the brain of your engine and transmission, and when it falters, it affects everything from performance to safety. Don’t let a faulty computer keep your reliable truck off the road. This is the straightforward, dependable solution you’ve been looking for.

An Old Pro’s Tip: Why VIN-Specific Programming is Non-Negotiable
“I’ve seen it a hundred times. Someone buys a used computer from a junkyard for their old Chevy, plugs it in, and suddenly they have more problems than they started with. That’s because on these late-90s GM trucks, the PCM is tied to everythingโthe engine size, the transmission type, the gear ratios, even the security system. Using a generic or incorrectly programmed module is like giving your truck a brain transplant with the wrong memories. Our VIN-specific programming ensures the computer knows your truck inside and out, just like the day it left the factory. It’s the only way to do the job right and ensure long-term reliability.”
Getting your truck, van, or SUV back to peak condition is simple. This professionally programmed 1999 Suburban 1500 PCM 16250279 is the most reliable and cost-effective way to solve complex electronic issues and restore the performance you depend on every day.
Frequently Asked Questions
How does the programming process work?
It’s simple! After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians use this number to flash the module with the correct, updated software from GM for your specific vehicle configuration before we ship it to you.
Is this a true plug-and-play unit?
Yes, because we program it to your VIN, it is designed to be plug-and-play. However, on many GM vehicles of this era, you may need to perform a simple security relearn procedure after installation, which syncs the new PCM with your vehicle’s anti-theft system. This procedure can typically be done yourself in about 30 minutes without special tools.
How do I confirm this is the right part for my vehicle?
The best way is to check the part number on your existing module. This PCM is a direct replacement for service numbers 16250279, 09366810, and 09355699. You can also use the detailed fitment list on this page to confirm compatibility with your make, model, and year.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the transmission’s shift points and line pressure. If the issue is electronic, a new, correctly programmed PCM like this 1999 Suburban 1500 PCM 16250279 can resolve harsh or erratic shifting. However, it will not fix internal mechanical failures within the transmission itself.
What information do you need from me?
The only piece of information we absolutely need is your vehicle’s VIN. This allows us to ensure the programming is a perfect match for your truck or SUV’s factory specifications.
