Is Your GM Vehicle Running Rough?
If you’re dealing with a persistent check engine light, erratic engine performance, harsh shifting, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, when the PCM falters, the entire vehicle suffers. I’ve seen it hundreds of times in the shop: customers replace sensor after sensor, only to find the root cause was the PCM all along.
The Direct Solution: A VIN-Programmed PCM
This isn’t just a replacement part; it’s a complete solution. We are offering a genuine GM Powertrain Control Module, part number 16236757, professionally programmed with the latest GM software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at checkout. This critical step ensures that the module communicates flawlessly with your car’s specific systems, just as it did from the factory.
A Story from the Shop Floor
“A customer’s ’98 Grand Prix came in last week with what they swore was a failing transmission. It was shifting hard and unpredictably. They were ready for a multi-thousand dollar repair bill. After hooking up the scanner, I saw no specific transmission fault codes, but the data stream from the PCM was erratic. We swapped in a VIN-programmed PCM like this one, and the car drove perfectly. The issue wasn’t the mechanical parts of the transmission; it was the computer telling it what to do. This simple fix saved them a fortune.”

Easy Installation for Your 1998 Monte Carlo PCM
Replacing the PCM is a straightforward job that most DIY mechanics can handle in their own driveway. Follow these simple steps to get your car back in top shape.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On many of these GM vehicles, the PCM is located in the engine bay, often inside the air filter box for protection. Consult a vehicle-specific guide if you’re unsure.
- Disconnect and Remove: Carefully unplug the electrical connectors. There are typically release tabs that need to be pressed. Once disconnected, unbolt the old module and remove it.
- Install the New PCM: Seat the new, programmed module in place and secure it with the original bolts. Reconnect the wiring harnesses, ensuring they click securely into place.
- Reconnect Battery: Re-attach the negative battery terminal. Your installation is complete and the vehicle is ready to start.
