Get Your Trusty Truck Running Like New
Is your Chevrolet or GMC truck suffering from frustrating issues like a persistent check engine light, erratic shifting, stalling, or even a no-start condition?

We offer the definitive solution: a reliable, VIN-programmed engine computer that gets you back on the road with confidence. This is the correct, hassle-free fix for your 1998-1999 Suburban 2500 PCM and a wide range of other GM vehicles.

If you’re experiencing any of the following, a faulty PCM is the likely cause:

- Engine misfires, runs rough, or stalls unexpectedly
- Harsh or delayed automatic transmission shifting
- Complete failure to start, even with a good battery and starter

An Expert’s Note: We had a customer, a contractor with a ’99 Express 2500 work van, who was about to lose a job because his van wouldn’t stay running. The shop quoted him over a thousand dollars for a new computer and programming. He was hesitant, but ordered our VIN-programmed module. It arrived two days later, he swapped it in the parking lot in 15 minutes, and the van fired right up and ran perfectly. He was back on the job site the same afternoon. For these workhorse vehicles, a reliable and fast solution for a failing 1998-1999 Suburban 2500 PCM isn’t a luxuryโit’s essential.
Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is any additional programming required after installation?
No, the core engine and transmission programming is complete. However, on many GM vehicles of this era, you may need to perform a simple security relearn procedure (often called a VATS relearn) to sync the computer with your key. This procedure takes about 30 minutes and can be done without any special tools.
Is this a new part?
No. This is a high-quality, tested computer that was sourced from a salvaged vehicle. Using proven OEM hardware is a reliable and cost-effective way to get your vehicle repaired correctly.
Will this fix my vehicle’s problem for sure?
While this module is the solution for the symptoms listed, it’s crucial to ensure your vehicle has been properly diagnosed. A faulty 1998-1999 Suburban 2500 PCM can mimic other issues, so please confirm the diagnosis before ordering.
What does the warranty cover?
This part is backed by our one-year replacement warranty. If the unit fails within one year of the purchase date, we will provide a replacement part.
