Get Your Workhorse Back on the Job
Is your reliable GMC Savana 3500 suddenly stalling, shifting erratically, or refusing to start?

This replacement engine computer is the straightforward, reliable solution to get your van out of the garage and back on the road, earning its keep.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of frustrating issues that are often misdiagnosed. If your van is experiencing any of the following, a failing computer is the likely culprit:

- Harsh or unpredictable automatic transmission shifting
- Engine stalling unexpectedly while driving or at idle
- Check Engine Light with communication error codes (like P0601, P0605)
- Poor fuel economy and reduced engine power
- Problems with the Vehicle Anti-Theft System (VATS)

Frequently Asked Questions
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your GMC Savana. This is essential for us to program the computer correctly for your specific vehicle configuration.
Is this a new part?
No, this is a genuine, used OEM computer that has been carefully removed from a salvaged vehicle. Each unit is tested to ensure it is fully functional and ready for programming and installation.
Will I need to do anything after installing it?
Because we program the PCM to your VIN, it is designed for a plug-and-play installation. In some cases, a Crankshaft Position System Variation (CASE) relearn procedure may be needed with a capable scan tool for optimal performance, but the vehicle will start and run without it.
How do I find my part number?
Your original PCM’s part number is printed on a sticker on the unit itself. It is typically located in the engine bay. This part replaces several numbers, including the common service ID 09355699, so as long as your vehicle is on the fitment list, this unit will work.
Does this part fit other vehicles?
Yes, this PCM is compatible with a wide range of 1998-1999 GM trucks, vans, and SUVs, including the Chevrolet Express, Tahoe, Suburban, and GMC Yukon, among others. Please check the detailed fitment list on this page to confirm compatibility.
