Restore Your GM Vehicle’s Core Performance and Reliability
If you’re dealing with frustrating issues like a persistent check engine light, erratic engine behavior, or a no-start condition in your 1998 Chevrolet Venture or other compatible GM vehicle, a failing Powertrain Control Module (PCM) is often the culprit. As the central computer for your engine and transmission, its health is critical. This replacement PCM, part number 9356741, is the definitive solution to get your vehicle running smoothly again. I’ve seen countless vehicles in my shop with mysterious electrical gremlins that all traced back to a faulty PCM. Replacing it correctly restores the vehicle to factory-spec operation.
What sets this module apart is our professional programming service. Before we ship it, we flash the unit with the latest official GM software updates using the VIN you provide. This critical step ensures 100% compatibility with your vehicle’s specific systems and options, eliminating the need for an expensive trip to the dealership for programming. You receive a part that is truly ready for installation right out of the box, saving you time, money, and headaches. A properly functioning 1998 Venture Powertrain Control Module is essential for optimal fuel economy, emissions compliance, and engine longevity.
A Technician’s Notebook: The Intermittent Stall Case
I once had a 1998 Chevy Venture in the bay that was a real head-scratcher. The owner complained of random stalling at stoplights and occasional hard shifting. There were no consistent trouble codes, just a generic P0601 (Internal Control Module Memory Check Sum Error) that would pop up now and then. We checked grounds, wiring, and sensors—all seemed fine. On a hunch, we swapped in a known-good, correctly programmed PCM. The stalling and shifting problems vanished instantly. The original module’s internal processor was failing intermittently under heat load, a common issue for these units after 20+ years. This experience solidified for me how a failing PCM can mimic a dozen other problems, making a reliable replacement the most effective fix.
Is Your Vehicle Exhibiting These Symptoms?
- âś” Check Engine Light is on with codes like P0601, P0602, P0606, or other communication errors.
- âś” Your vehicle fails to start or starts and immediately stalls.
- âś” Noticeable decrease in fuel economy.
- âś” Harsh or erratic automatic transmission shifting.
- âś” The engine runs rough, misfires, or hesitates during acceleration.
- âś” Failure to pass state emissions testing.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- âś” Locate the PCM: On the 1998 Venture, the PCM is typically located in the engine compartment, often inside the air filter housing assembly for protection. Consult a repair manual for your specific model if you’re unsure.
- âś” Disconnect Connectors: Carefully unclip and remove the electrical wiring harnesses from the old module. These connectors have locking tabs that must be released to prevent damage.
- âś” Remove the Old Module: Unbolt the old PCM from its mounting bracket. Keep the hardware as you may need it for the new installation.
- âś” Install the New Module: Mount your new, pre-programmed 1998 Venture Powertrain Control Module in place and securely fasten it.
- âś” Reconnect Everything: Plug the wiring harnesses firmly back into the new PCM until they click into place. Reconnect the negative battery terminal.
- âś” Perform Security Relearn: Most GM vehicles of this era require a simple security relearn procedure to sync the new PCM with your key’s anti-theft chip. This usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the PCM with the correct software for your vehicle’s specific engine, transmission, and options. This ensures seamless integration and proper function without requiring a trip to the dealer.
Is this a simple plug-and-play installation?
Yes, for the most part. Because we pre-program the module, you won’t need any special scan tools. However, you will need to perform a simple security relearn procedure after installation, which typically takes about 30 minutes using only your ignition key.
Will this fix my transmission shifting problems?
If the shifting problems are caused by a faulty PCM, then yes. The PCM controls transmission shift points and line pressure. A failing module is a very common cause of erratic shifting, and replacing it with this correctly programmed unit will resolve those electronic issues.
Do I need to send my old part back?
This listing does not require a core return. You can keep or dispose of your old module, saving you the hassle and cost of return shipping.
Is this compatible with other part numbers?
Yes, this part is a direct replacement for several service numbers, including 09356741, 16236757, 9357034, 9357440, and 9366314. If your original module has one of these numbers, this part will work for your vehicle.
