Get Your Dependable GM Truck or Van Running Right Again
Is your trusty Chevrolet Astro, Express van, or GMC truck suddenly unreliable? If you’re dealing with frustrating issues like stalling, a rough idle, poor fuel economy, or a dreaded no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s downtime that costs you time and money. This fully programmed 1998 Chevy Astro PCM is the straightforward, reliable solution to get your workhorse back on the road, performing exactly as it should.
Common Symptoms & Your Solution
A faulty PCM can cause a cascade of confusing problems that can be difficult to diagnose. If your vehicle is experiencing any of the following, this module is your definitive fix:
- Engine stalling or cutting out unexpectedly
- Rough or erratic idling
- Failure to start, even with a good battery and starter
- Poor acceleration and loss of power
- Harsh or incorrect transmission shifting
- Check Engine Light with communication error codes or false sensor codes (e.g., P0300, P0171, P0174)

An Expert’s Note on “Plug & Play”
As a technician, one of the biggest headaches with older vehicles like these late-90s GM trucks is module replacement. In the past, you’d install a new computer only to find the vehicle still won’t start because it needs to be programmed by a dealer with expensive equipment. It’s a frustrating, time-consuming, and costly extra step. Our service eliminates that entire process. By sending you a programmed 1998 Chevy Astro PCM that’s already matched to your truck, we turn a complex electronic repair into a simple mechanical swap. You’re not just buying a part; you’re buying a complete, hassle-free solution.
Frequently Asked Questions
Is any additional programming required after I install this?
No. This PCM is delivered fully programmed to your vehicle’s VIN and is ready for installation right out of the box. In some cases, a security relearn procedure may be necessary, which is a simple process that can be done without any special tools. We include instructions for this.
What happens after I place my order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship the computer without it. Once we have your VIN, we will program the module and typically ship it within one business day.
Where do I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, your insurance card, or on the vehicle itself. Look for a small metal plate on the driver’s side of the dashboard (visible through the windshield) or on the sticker inside the driver’s side door jamb.
What part numbers does this PCM replace?
This computer is a direct replacement for a wide range of part numbers, including 09355699, 16266645, 16250279, 16258815, and 9366810. If your original module has one of these numbers, this unit will work for you.
Is this a new part?
No, this is a high-quality, used OEM computer that has been sourced from a salvaged vehicle. Each unit is tested to ensure it is fully functional before being programmed and shipped to you.
