Restore Peak Performance to Your GM Truck or SUV
Is your 2000 GMC Yukon or other GM vehicle suffering from frustrating issues like intermittent stalling, a persistent Check Engine Light, or a complete no-start condition? You’re not alone. As a technician with over two decades of experience, I’ve seen firsthand how a failing Powertrain Control Module (PCM) can wreak havoc on your vehicle’s reliability. The PCM is the electronic brain of your engine and transmission, and when it starts to fail, the symptoms can be unpredictable and difficult to diagnose. This replacement 2000 Yukon Powertrain Module is the definitive solution to restore your vehicle’s factory performance and dependability.
We take the guesswork and extra cost out of the repair. Unlike sourcing a part from a junkyard or a dealership, this module comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load the latest GM-certified software updates before it ships, ensuring optimal fuel economy, emissions compliance, and transmission shift points. This means no expensive trips to the dealer for programming—it’s ready for installation right out of the box.
Is Your GM Vehicle Showing These PCM Failure Signs?
- ✔ Check Engine Light is on with communication error codes like P0601, P0602, or P0606.
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling, especially when the engine is warm.
- ✔ A noticeable drop in fuel mileage.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass a state emissions inspection.
- ✔ Your scan tool cannot communicate with the PCM.
From the Diagnostic Bay
I remember a 2000 Chevy Tahoe that came into my shop with a maddeningly intermittent no-start condition. The owner had already replaced the battery, alternator, and crank sensor. It would run fine for days, then refuse to start. After hours of testing, I noticed the fuel pump wasn’t priming during the no-start events. A tap on the PCM under the hood sometimes brought it back to life. It turned out to be internal solder joint failure, a classic issue on these units, especially after years of heat cycles. We installed a pre-programmed module just like this one, and the truck has been running reliably ever since. This isn’t just a part; it’s a permanent fix for a common and frustrating problem.
Straightforward Installation Guide
Installing your new 2000 Yukon Powertrain Module is a job most DIYers can handle in under an hour with basic hand tools. Following these steps ensures a smooth process.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most trucks and SUVs like the Yukon, Tahoe, and Silverado, the PCM is located under the hood on the driver’s side, typically below or next to the battery in a black plastic bracket. On F-body cars like the Camaro and Firebird, it’s behind the passenger side strut tower.
- Disconnect the Connectors: Carefully unclip and remove the electrical wiring harness connectors from the old PCM. These connectors have locking tabs that need to be released. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Seat the new, pre-programmed module into the mounting bracket and secure it. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn (If Necessary): In many cases, you will need to perform a simple key-cycle security relearn procedure, which takes about 30 minutes. This allows the new PCM to recognize your vehicle’s anti-theft system. Instructions are readily available online for your specific model.

Do I need to do anything after I purchase?
Do I need to do anything after I purchase?
Yes. After you place your order, you must send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. This ensures the software is perfectly matched to your vehicle’s factory specifications.
Is this a plug-and-play part?
Mostly, yes. Because we program it to your VIN, it does not require a trip to the dealer. However, on most GM vehicles of this era, you will need to perform a security relearn procedure which involves a series of key cycles. This simple procedure syncs the new PCM with your existing keys and can be done in your driveway.
Will this fix my transmission shifting problems?
If the shifting problems are caused by a faulty PCM, then yes. The PCM controls transmission line pressure and shift points. A failing module is a very common cause of erratic shifting, and replacing it with this correctly programmed unit will restore proper function.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) typically just controls the engine. ECU (Electronic Control Unit) is a generic term. PCM (Powertrain Control Module) is the most accurate term for this part, as it controls both the engine and the automatic transmission functions together in one unit.
Do I need to send my old part back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
