Is Your GM Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
It’s a frustrating experience when your trusted car, be it a Cutlass, Grand Prix, or Bonneville, starts acting unpredictably. You’re likely dealing with erratic shifting, a rough idle, or even a no-start condition that leaves you stranded. These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. Don’t let a faulty computer dictate your day. This fully programmed 1999 Cutlass PCM 09361735 is the reliable, straightforward solution to get your vehicle running like it should.

- Vehicle won’t start or stalls intermittently
- Poor fuel economy and engine performance
- Harsh or incorrect automatic transmission shifting
- Communication errors with diagnostic scan tools

From the Expert’s Bench: A common mistake DIYers make with these late-90s GM vehicles is buying a used PCM from a junkyard and expecting it to work. It won’t. These cars use a Vehicle Anti-Theft System (VATS or Passlock) that is tied to the original PCM’s programming. Plugging in a different, unprogrammed module will result in a no-start condition every time. Our service eliminates that entire headache. By programming the module to your VIN before shipping, we ensure the security systems match, saving you time, money, and the frustration of a car that won’t run.
Frequently Asked Questions
How do I provide my VIN number?
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 essential for it to function in your car.
Is this part difficult to install?
For most of the listed vehicles, the PCM is located in the engine compartment and is relatively easy to access. Installation typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. Since it comes pre-programmed, no special tools are required.
What does ‘used’ mean for this part?
This PCM was carefully removed from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped. It’s a reliable and economical way to get your car back in working order.
Will I need to do anything after installation?
In some cases, a ‘Security Relearn Procedure’ may be necessary to fully sync the new PCM with your vehicle’s anti-theft system. This is a simple procedure that typically involves turning the key to the ‘ON’ position for 10-15 minutes and can be done without any special tools. We can provide instructions if needed.
How can I be sure this fits my car?
Please check the extensive fitment list provided in the description. This 1999 Cutlass PCM 09361735 fits many models, but matching your vehicle, year, and engine is crucial. Providing your VIN for programming is the final step that guarantees compatibility.
