Restore Peak Performance to Your GM Vehicle
Is your 2000 GMC Yukon, Silverado, or Tahoe running rough, shifting erratically, or failing to start? These are classic signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your vehicle’s engine and transmission. A faulty PCM can lead to a cascade of frustrating issues, from a persistent Check Engine Light to a complete no-start condition. This direct-fit replacement Powertrain Control Module, part number 19109040, is the definitive solution to get your truck or car running like new again.
Unlike generic modules that require expensive trips to the dealership for programming, this unit comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest GM-certified software updates before it ships, ensuring optimal performance, fuel efficiency, and emissions control. This plug-and-play approach saves you time, money, and the headache of coordinating with a repair shop for programming services. Simply provide your VIN during checkout, and we handle the rest.
From the Diagnostic Bay
We had a 2000 Silverado 1500 in the shop that was giving the owner fits. The truck would randomly stall at stoplights and had a harsh 1-2 gear shift. The owner had already replaced the throttle position sensor and the mass airflow sensor, but the problems persisted. After hooking up our diagnostic scanner, we noticed intermittent communication drops with the engine computer. We swapped in one of our pre-programmed modules, and the truck immediately ran smoothly. The issue wasn’t a faulty sensor, but the central computer failing to properly process the data. This highlights how a failing PCM can mimic other component failures, making a quality replacement the true fix.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or misfiring.
- ✔ Rough or inconsistent idling.
- ✔ Poor acceleration and overall lack of power.
- ✔ Decreased fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Intermittent or complete no-start condition.
- ✔ Failure to communicate with diagnostic scan tools.
Why Choose Our Pre-Programmed 2000 Yukon Powertrain Module?
This isn’t just a replacement part; it’s a comprehensive solution. The internal electronics of the original PCMs from this era are prone to failure from heat, vibration, and age. Our modules are meticulously inspected to ensure they meet or exceed original equipment specifications for reliability and longevity. By programming the module with your VIN, we ensure all factory-installed options on your vehicle—like engine size, transmission type, and emissions equipment—are correctly recognized. This eliminates compatibility guesswork and ensures a seamless installation process. This module is a direct replacement for part numbers 19109040, 09354896, and 9354896.
Frequently Asked Questions
What exactly does the Powertrain Control Module (PCM) do?
The PCM is the main computer for your vehicle. It takes information from sensors all over the engine and transmission to control critical functions like fuel injection, ignition timing, and transmission shift points to ensure the vehicle runs efficiently and cleanly.
Do I need to have this module programmed by a dealer?
No. This is the biggest benefit of our service. We program the module with your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you hundreds of dollars in dealership programming fees.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this module will resolve the issue. However, it’s crucial to ensure the underlying cause is the module itself and not a separate sensor or wiring problem. We always recommend a proper diagnosis before ordering.
Is any special procedure needed after I install it?
In many cases, it’s a simple plug-and-play installation. However, on some GM vehicles, you may need to perform a security relearn procedure (also known as a Passlock or VATS relearn). This procedure syncs the new PCM with your vehicle’s anti-theft system and can typically be done in your driveway with just the ignition key. Instructions are widely available online for your specific model.
Where do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard visible through the windshield. It is also located on the sticker in the driver’s side door jamb.
Does this fit vehicles other than the 2000 GMC Yukon?
Yes, this module has a wide range of applications across the GM family from 1999-2002. It fits many Chevrolet Silverado, GMC Sierra, Tahoe, Suburban, Camaro, and Firebird models. Please verify the part number or consult the fitment list on our page to ensure compatibility.
