Get Your Savana 3500 Back on the Job, Fast.
When your 1998 GMC Savana 3500 isn’t running right, your entire workday grinds to a halt. An unpredictable engine, poor performance, or a persistent Check Engine Light aren’t just annoyancesโthey’re threats to your livelihood. This Powertrain Control Module (PCM) is the definitive, reliable solution to get your workhorse back in service. We take the guesswork out of the repair by programming this module specifically to your van’s VIN with the latest GM software updates. It arrives at your door ready for a straightforward installation, saving you from costly diagnostic fees and programming charges at a dealership.
Common Symptoms & Your Solution
A failing engine computer can cause a host of frustrating and difficult-to-diagnose issues. If your Savana is experiencing any of the following, a faulty PCM is the likely culprit:
- No Start or Hard Starting: The engine cranks but refuses to fire up, or takes an excessive amount of time to start.
- Rough Idle & Stalling: Your van runs erratically, shakes at stoplights, or stalls unexpectedly.
- Poor Fuel Economy: You’re making more trips to the gas station than usual due to incorrect fuel and air mixture control.
- Check Engine Light: You may see diagnostic trouble codes (DTCs) such as P0601, P0605, or P0606, indicating an internal module failure.
- Harsh or Failed Shifting: The PCM also controls transmission functions, and a bad unit can lead to erratic shifting or getting stuck in gear.
This pre-programmed 1998 GMC Savana 3500 PCM 09355699 is the direct answer to these problems, restoring the factory performance and dependability you need to get the job done.
Expert Insight: The Down-for-the-Count Contractor
We recently worked with a plumber whose ’98 Savana was his mobile office. It started stalling at intersections, forcing him to cancel a high-paying emergency job. The shop quoted him a massive bill and a week-long wait for a new computer and programming. He ordered this module from us instead. After providing his VIN, the part arrived two days later. He installed it in under an hour and, after a quick security relearn, the van fired up perfectly. He was back on the road the same afternoon, saving the client relationship and avoiding hundreds in lost income. That’s the difference a ready-to-install part makes.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before shipment. You just need to provide us with your vehicle’s VIN after purchase. The only thing you may need to perform after installation is a security relearn procedure (also known as a CASE learn), which can typically be done without special tools and instructions can be easily found online.
How do I send you my VIN?
After you complete your purchase, simply send us a message with 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 this compatible with other GM vehicles?
Yes, this module fits a wide variety of GM trucks, vans, and SUVs from the late 1990s. Please review the detailed fitment list on this page to confirm it is the correct part for your specific make, model, and engine.
What does the Powertrain Control Module (PCM) do?
The PCM is the central computer of your vehicle. It controls all aspects of engine and transmission function, including fuel injection, ignition timing, emissions systems, and shift points, to ensure optimal performance, fuel efficiency, and reliability.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (like codes P0601 or P0605), then this replacement 1998 GMC Savana 3500 PCM 09355699 is the correct solution. However, you should always ensure other potential issues like faulty sensors have been ruled out first.
