Restore Your GM Vehicle’s Core Performance
Is your 1996 Buick LeSabre, or another classic GM vehicle, suffering from frustrating engine problems? Unexplained stalling, a persistent Check Engine Light, or a complete no-start condition can often be traced back to a failing Powertrain Control Module (PCM), the electronic brain of your vehicle.

Simply provide your vehicle’s VIN during checkout, and our technicians will load the latest, most stable GM factory software directly onto the module. It arrives at your door ready for a simple, plug-and-play installation, restoring the precise engine and transmission management your car had when it was new. This is the most efficient way to get your vehicle back to running smoothly.
Is Your Vehicle Showing These Symptoms?
- ✔ Sudden stalling or engine cutting out while driving.

- ✔ An illuminated Check Engine Light with internal processor error codes (e.g., P0601, P0605, P0606).
- ✔ Poor or erratic automatic transmission shifting.
- ✔ A noticeable drop in fuel economy.
- ✔ Communication errors with diagnostic scan tools.
From the Diagnostic Bay
I remember a 1996 Buick Park Avenue that came into my shop on a tow truck. The owner was frustrated because it would run fine for 20 minutes, then stall without warning and refuse to restart for an hour. There were no consistent trouble codes, just a general communication loss when it was acting up. After checking all the power and ground circuits to the PCM, we suspected an internal failure that was triggered by heat. We swapped in one of our pre-programmed modules, and the car ran perfectly for a two-hour test drive. It’s a classic example of how a failing 1996 LeSabre PCM can cause intermittent issues that are a nightmare to diagnose without a known-good part to test with.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the PCM: On most of these GM models, the PCM is located in the engine bay, often inside the air filter box housing for protection.
- ✔ Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old module. They have locking tabs that need to be released.
- ✔ Remove the Old Module: Unbolt or unclip the old PCM from its mounting bracket and remove it from the vehicle.
- ✔ Install the New PCM: Mount your new, pre-programmed PCM in the same location and securely re-attach the wiring harness connectors. You should hear a click as they lock in place.
- ✔ Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start. No further programming is required.
