Restore Peak Performance to Your GM Vehicle
Is your 1999 Buick Park Avenue, Grand Prix, or another compatible GM vehicle suffering from perplexing engine issues? Unexplained stalling, a persistent check engine light, or erratic performance can often be traced back to a failing Powertrain Control Module (PCM). This component is the brain of your vehicle, orchestrating everything from fuel injection and ignition timing to transmission shifting. When it falters, the entire driving experience is compromised. This genuine OEM Powertrain Control Module, part number 09361735, is the definitive solution to restore your vehicle’s original functionality and reliability.
From the Diagnostic Bay
I once had a 1999 LeSabre come into the shop with an intermittent no-start condition that had stumped two other mechanics. The owner was frustrated, having already replaced the battery, starter, and fuel pump. We could find no codes, and the car would start fine for days, then suddenly refuse. After hours of tracing wires, we hooked up a scope to the PCM’s main communication lines. We noticed that during the no-start events, the data stream was just noise. The internal processors of the PCM were failing under certain temperature conditions. We installed a VIN-programmed replacement unit just like this one, and the car never failed to start again. It’s a reminder that sometimes the most elusive problems lead back to the vehicle’s central computer.
Why Choose Our Pre-Programmed 1999 Park Avenue PCM?
The biggest hurdle in replacing a modern vehicle’s computer is programming. A module from another vehicle won’t work without being properly configured to your car’s specific Vehicle Identification Number (VIN) and options. Our service eliminates this complex and expensive step. We handle the programming for you before we ship the part. Using the latest GM software updates, we flash this PCM with your vehicle’s exact data. The result is a true plug-and-play component that is ready for installation right out of the box, saving you a trip to the dealership and costly programming fees.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various codes, or no codes at all.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic idling and poor engine performance.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Failure to communicate with diagnostic scan tools.
Guaranteed Fitment and Simple Installation
This module is a direct replacement for part number 09361735 and is confirmed to fit a wide range of GM vehicles.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of the engine and transmission, including fuel mixture, spark timing, emissions systems, and gear shifting, to ensure optimal performance, fuel efficiency, and low emissions.
Do I need to do any programming myself?
No. This is the primary benefit of our service. We program the PCM to your vehicle’s specific VIN before we ship it to you. It will arrive ready to be installed with no additional programming required.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). You can find your VIN on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
Is this a new part?
This is a high-quality, used OEM part that has been carefully sourced from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then this replacement part will solve the issue. However, the check engine light can be triggered by many different components. It is essential to have your vehicle properly diagnosed to confirm the PCM is the root cause of the problem.
