Is your 1998 Chevrolet Venture or other compatible GM vehicle suffering from perplexing issues like stalling, poor fuel economy, erratic shifting, or a persistent check engine light? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine and transmission. Don’t let a faulty module keep you off the road. This direct-fit replacement PCM is the reliable, straightforward solution to restore your vehicle’s performance and dependability.
This isn’t just a part in a box; it’s a complete service. We take the guesswork and expensive dealership trips out of the equation. Upon purchase, simply provide us with your vehicle’s VIN. Our technicians will then program the module with the latest, most stable GM-certified software specific to your vehicle’s configuration. This ensures that when the part arrives, it’s ready for a simple, plug-and-play installation, getting you back on the road faster.
From the Diagnostic Bay
We had a 1998 Oldsmobile Silhouette come in that was driving the owner crazy. It had a rough idle and would occasionally stall at red lights. The previous shop had replaced the Idle Air Control (IAC) valve and the throttle position sensor, but the problem persisted. After hooking up our scanner, we noticed erratic data coming from the PCM. Instead of continuing to throw parts at it, we identified the core issue: the module itself was failing. We installed a VIN-programmed PCM just like this one, and the van ran like new. It’s a powerful reminder that sometimes the ‘brain’ is the source of the problem, not just the sensors it’s reading.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Poor engine performance, including misfires, hesitation, or stalling
- ✔ Decreased fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass emissions testing
- ✔ Vehicle entering ‘limp mode’ with reduced power
- ✔ Complete no-start condition where the engine cranks but won’t fire

Our programming service uses your VIN to load the exact factory specifications and all subsequent updates from GM, ensuring optimal engine performance, transmission control, and fuel economy. This process eliminates compatibility issues and the need for expensive dealer-only programming tools.
This part is a direct replacement for the following service numbers: 09356741, 16236757, 9357034, 9357440, 9366314.
Installation is straightforward for any competent DIY mechanic or professional technician. Once you receive the programmed module, simply disconnect the battery, locate and swap the old module with the new one, and reconnect the battery. In some cases, a simple security relearn procedure may be necessary, which can typically be done without any special tools.
Frequently Asked Questions
Do I need to have this module programmed?
No. The main benefit of our service is that we program the module for you before shipping. Just provide your vehicle’s VIN at checkout, and it will arrive ready to install.
What is a VIN and where can I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my check engine light?
If the check engine light is on due to an internal fault within the PCM, then yes, this part will resolve the issue. However, if the light is on because of a faulty sensor or other component, that part will still need to be addressed.
Is any other setup required after I install it?
In many cases, it’s a simple plug-and-play installation. Some GM vehicles may require a security relearn procedure (also known as a CASE learn or Passlock relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available online.
Is this compatible with vehicles other than the 1998 Venture?
Yes, this module is compatible with a wide range of 1998-1999 GM vehicles that use the listed service numbers, including models like the Grand Am, Century, Malibu, and Lumina. Please check the full fitment list on this page to confirm compatibility with your specific vehicle.
