Restore Your Truckโs Brain and Get Back on the Road
Is your truck running rough, shifting erratically, or refusing to start? A failing Powertrain Control Module (PCM) can bring your reliable GM truck or SUV to a dead stop, leaving you frustrated and stranded. This isn’t just an inconvenience; it’s a critical failure of the vehicle’s central computer. This replacement PCM is the definitive, hassle-free solution to restore your vehicle’s performance, fuel economy, and dependability. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle using your VIN, ensuring a seamless installation process right out of the box.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a faulty PCM is the likely culprit. This module is the solution for:
- Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs).
- Poor or erratic automatic transmission shifting.
- Engine stumbling, misfiring, or stalling.
- Complete no-start condition where the engine cranks but won’t fire.
- Reduced fuel economy.
- Failure to pass an emissions test.
By installing our Programmed 1998-1999 GMC Yukon PCM 09366810, you are not just replacing a part; you are restoring the core logic that controls your engine and transmission, ensuring all components work in harmony as the factory intended.
An Expert’s Note on GM Programming
“On these late-90s GM Vortec platforms, the PCM is everything. It doesn’t just manage fuel and spark; it’s in constant communication with the transmission, ABS, and security systems. Simply swapping in a used module from a junkyard won’t workโthe VIN mismatch will prevent it from starting or cause severe drivability issues. Our VIN-programming service installs the latest GM-approved software for your specific vehicle. This corrects common factory bugs and ensures the module communicates perfectly with your truck’s 4L60E or 4L80E transmission, giving you smoother shifts and restored engine power. It’s the correct way to do this repair.”

Frequently Asked Questions
Do I need to do any programming after I install this PCM?
No. This module comes fully programmed to your vehicle’s VIN and is ready for installation. In some cases, a simple security relearn procedure (often called a ‘key-on/key-off’ cycle) may be necessary, which you can do yourself in your driveway without any special tools.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your truck.
What if my original part number doesn’t match exactly?
This module is a direct replacement for several part numbers, including 16250279 and 09355699. As long as your vehicle’s year, make, and model are on the compatibility list, this unit will function correctly once programmed to your VIN.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the transmission’s shift points and line pressure. If your transmission issues are electronic in nature (and not caused by an internal mechanical failure), this module is often the solution for harsh or erratic shifting.
Is this part difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The PCM is usually located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. It generally takes less than an hour.
