Restore Peak Performance to Your GM Vehicle
If you’re dealing with a frustrating Check Engine Light, erratic engine behavior, or transmission shifting problems in your 1998 Chevrolet Venture or other compatible GM model, a failing Powertrain Control Module (PCM) is often the culprit. As the central computer for your vehicle, the PCM controls everything from fuel mixture and ignition timing to transmission shift points. When it fails, the symptoms can be widespread and confusing. This replacement PCM, part number 09356741, is the reliable, straightforward solution to get your vehicle back on the road and running smoothly.
We take the guesswork and high cost out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit comes professionally programmed with the latest GM-approved software updates specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we’ll flash the module before it ships. This ensures it’s a true plug-and-play solution, eliminating the need for expensive dealership programming or specialized scan tools.
From the Diagnostic Bay: The Case of the Confused Minivan
A customer brought in a 1998 Chevy Venture with a complaint that stumped a couple of other shops. It had an intermittent no-start condition, and when it did run, the transmission would slam into gear. They had already replaced the crank sensor and a transmission solenoid pack with no luck. The Check Engine Light was on, but the codes were inconsistent. In my experience, when you see a mix of seemingly unrelated engine and transmission codes, the PCM itself is a prime suspect. We connected our diagnostic equipment and saw erratic data streams from the PCM. We installed one of our pre-programmed modules, performed the simple security relearn, and the van started perfectly and shifted like new. It’s a classic example of how a faulty 1998 Venture Powertrain Control Module can mimic multiple other failures.
Is Your GM Vehicle Showing These PCM Failure Signs?
A failing PCM can cause a variety of issues. If you’re experiencing any of the following, this module is likely the solution you need:
- âś” Persistent Check Engine Light (CEL)
- âś” Diagnostic Trouble Codes (DTCs) such as P0601 (Internal Control Module Memory Check Sum Error) or P0605 (Internal Control Module ROM Error)
- âś” Harsh or erratic automatic transmission shifting
- âś” Engine cranks but will not start
- âś” Poor fuel economy
- âś” Stalling or rough idling
- âś” Failure to pass an emissions test
A Straightforward Guide to Installation
Installing your new 1998 Venture Powertrain Control Module is a manageable job for a DIY enthusiast. While the exact location varies slightly by model, the general process is the same.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the PCM: On most of these vehicles, including the Venture, Silhouette, and Trans Sport, the PCM is located in the engine compartment, often inside the air filter housing for protection. On some sedans, it may be under the dash.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. They have locking tabs that need to be released. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed PCM into place and securely reconnect the wiring harnesses. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Security Relearn: Most GM vehicles of this era require a simple key-cycle security relearn procedure to recognize the new PCM. Turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds. Repeat this two more times. On the fourth try, the vehicle should start.

Do I need to program this module?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation and a simple security relearn procedure.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Where is the PCM located on my 1998 Venture?
On the 1998 Chevy Venture and its sister minivans (Silhouette, Trans Sport), the PCM is typically located inside the air cleaner assembly box in the engine compartment for protection.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the transmission’s electronic solenoids. If the module is failing, it can cause harsh shifting, delayed engagement, or failure to shift. This part often resolves those issues.
Is the security relearn procedure difficult?
Not at all. It requires no special tools, just your ignition key and about 30 minutes of time. The simple ‘key on, key off’ cycle allows the vehicle’s anti-theft system to synchronize with the new PCM.
