Restore Peak Performance to Your GM Truck or SUV
Is your trusty Yukon, Tahoe, or Silverado suddenly acting up? Unexplained stalling, erratic shifting, a persistent check engine light, or a frustrating no-start condition can quickly turn a reliable vehicle into a source of daily stress. These are classic signs that the brain of your engine, the Powertrain Control Module (PCM), may be failing. Don’t let a faulty computer sideline your vehicle. This direct-fit PCM is the definitive solution to bring back the smooth, dependable performance you rely on, getting you back on the road with confidence.

This module arrives at your doorstep fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest, most stable software updates from GM, ensuring optimal fuel economy, emissions compliance, and engine performance right out of the box. It’s a true plug-and-play solution designed for a hassle-free installation.
A Mechanic’s Note: The Ghost in the Machine
I once had a 1999 Suburban in the shop that was driving its owner crazy. It would run perfectly for days, then suddenly die at a stoplight and refuse to restart for an hour. No consistent codes, just intermittent chaos. We checked everything—fuel pressure, spark, sensors. Finally, we tapped on the old PCM while it was acting up, and the engine sputtered. A hairline crack in the circuit board was causing a thermal-related failure. Installing a properly programmed 1998-1999 Yukon PCM didn’t just fix the problem; it gave the owner back the peace of mind to take his family on road trips again. That’s the real value of a solid repair.
Warning Signs Your PCM Needs Attention
- ✔ Check Engine Light: Persistent illumination with communication error codes (like P0601, P0605) or multiple unrelated sensor codes.
- ✔ Engine Performance Issues: Rough idling, hesitation during acceleration, misfires, or a noticeable drop in fuel efficiency.
- ✔ Transmission Problems: Harsh or delayed shifting, or getting stuck in one gear (limp mode).
- ✔ No-Start Condition: The engine cranks but won’t start, and you’ve already ruled out fuel and spark issues.
- ✔ Intermittent Stalling: The vehicle dies unexpectedly while driving or at idle, often without a clear pattern.
Guided Installation for a Confident Fix
You can do this. Replacing the PCM is one of the more straightforward electronic repairs. All you need are basic hand tools and about 20-30 minutes. Follow these steps to restore your vehicle’s brainpower.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most of these GM trucks and vans, the PCM is located in the engine bay, typically on the driver’s side near the battery or firewall, housed in a black plastic bracket.
- Disconnect the Old Unit: Carefully unplug the electrical connectors. They have locking tabs that may need to be lifted or slid to release. Once disconnected, unbolt the module from its mounting bracket.
- Install the New PCM: Seat your new, pre-programmed PCM into the mounting bracket and secure it. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Power Up: Reconnect the negative battery terminal. Your vehicle is now ready to go. In some cases, a simple security relearn procedure may be necessary, which can be done without special tools (instructions are readily available online or can be provided).

Frequently Asked Questions
Do I need to do anything after installing this PCM?
Because this module comes programmed to your VIN, it is nearly plug-and-play. However, you will need to perform a security relearn procedure (also known as a CASE relearn) to sync the PCM with your vehicle’s anti-theft system. This is a simple procedure that takes about 30 minutes and does not require any special tools.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is this a new or a used part?
This is a professionally inspected and certified genuine OEM part that has been meticulously tested to meet or exceed original factory specifications. It is then programmed with the latest software for your specific vehicle.
