Restore Peak Performance to Your GM Vehicle
Is your GMC Yukon, Sierra, or Chevrolet Silverado suffering from frustrating issues like a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer of your vehicle. Don’t let a faulty module keep you off the road. This direct-fit replacement PCM, part number 19109040, is the definitive solution to restore your vehicle’s reliability and drivability.
Unlike generic modules that require expensive trips to the dealership for programming, this PCM arrives at your door completely flashed with the latest official GM software updates. We use your vehicle’s unique Vehicle Identification Number (VIN) to ensure a perfect match, creating a seamless installation process. This critical step ensures all engine and transmission parameters are set to factory specifications for your specific vehicle, eliminating guesswork and compatibility problems.
I once had a 2000 Silverado 2500 in the bay that was driving the owner crazy. He had replaced the throttle position sensor, the mass airflow sensor, and even a couple of transmission solenoids trying to chase down an intermittent hard shift and a stalling problem. The codes were all over the place. After checking the wiring harnesses for the third time, we finally scoped the PCM’s outputs and found they were dropping out randomly. We installed a VIN-programmed module, performed the CASE relearn, and the truck ran like it just rolled off the assembly line. It’s a powerful reminder that when multiple, seemingly unrelated electronic systems act up, the brain of the operation—the PCM—is often the culprit.
Is Your Vehicle Exhibiting These Symptoms?
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, a faulty module is a likely cause:
- ✔ Persistent Check Engine Light (CEL) with codes related to internal module failure (e.g., P0601, P0606).
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Unexplained drop in fuel mileage.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent failure of multiple electronic components.

Frequently Asked Questions
Do I need to program this module?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and it will arrive ready for installation and a final security relearn.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What is a CASE relearn and is it difficult?
A CASE (Crankshaft Angle Sensor Error) relearn is a procedure that syncs the new PCM with your engine’s crankshaft position sensor. For most of these GM vehicles, it’s a simple process that we provide full instructions for. It helps ensure accurate ignition timing and prevents certain trouble codes.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of your existing PCM (common codes include P0601-P0606), then this replacement module will resolve the issue. It’s always best to have your codes read by a scanner to confirm the diagnosis before ordering.
What part numbers does this module replace?
This module is a direct replacement for OEM part numbers 19109040, 09354896, and 9354896. If your original module has one of these numbers, this is the correct part for you.
