Programmed 1999-2000 Silverado 1500 PCM 09354896

### 1999-2000 Silverado 1500 PCM 09354896 \| Pre-Flashed to Your VIN   ## Restore Your Truck’s Brain and Get Back on the Road with Confidence Is your Silverado, Sierra, or Tahoe suddenly acting possessed? Stalling at red lights, shifting erratically, or displaying a stubborn Check Engine Light can be incredibly frustrating. These aren’t just annoyances; they’re signs that your vehicle’s central command center—the Powertrain Control Module (PCM)—may be failing. This isn’t just another part; it’s the core of your truck’s performance and reliability. We offer a dependable, straightforward solution: a replacement PCM, part number **09354896**, programmed specifically for your vehicle’s VIN with the latest GM software updates. ### Warning Signs Your PCM is Calling for Help A failing computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty module could be the culprit: - ✔ **Check Engine Light:** Persistent illumination with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606. - ✔ **Engine Performance Issues:** Unexplained stalling, rough idling, hesitation during acceleration, or a noticeable drop in fuel economy. - ✔ **No-Start Condition:** The engine cranks but refuses to start, even with a good battery and fuel supply. - ✔ **Transmission Problems:** Harsh or delayed shifting, or getting stuck in a single gear (limp mode). - ✔ **Intermittent Electrical Gremlins:** Gauges behaving erratically or other strange electronic behavior that comes and goes. ### Guided Installation to Restore Your Truck’s Performance Replacing the brain of your truck might sound intimidating, but it’s a manageable job for a DIYer with basic tools. Our goal is to make this process as smooth as possible. Here’s a simple guide to get you through it. 1. **Safety First:** Begin by disconnecting the negative terminal from your vehicle’s battery. This is a critical step to prevent electrical shorts and protect both you and the vehicle’s electronics. 2. **Locate the Module:** On most of these GM trucks and SUVs, the PCM is located in the engine bay, on the driver’s side, underneath or next to the battery tray. You may need to remove the battery to gain access. 3. **Disconnect the Harnesses:** The PCM has several large multi-pin electrical connectors. Carefully release the locking tabs or levers on each connector and gently pull them straight out from the module. Never force them. 4. **Swap the Modules:** Unbolt the old PCM from its mounting bracket. Set the new, pre-programmed module in its place and secure it with the original hardware. 5. **Reconnect and Finalize:** Firmly plug the electrical harnesses back into the new PCM, ensuring they click securely into place. Reinstall the battery and connect the negative terminal. Your installation is complete! In some cases, a security relearn procedure may be necessary, which can often be done without special tools. > #### Expert Technician’s Tip > > Before installing your new **1999-2000 Silverado 1500 PCM**, take a moment to inspect your vehicle’s main battery cables and engine ground straps. A corroded or loose ground is a common cause of PCM failure and can damage a new unit. Cleaning the contact points with a wire brush and ensuring a tight connection is a five-minute job that can save you from a repeat failure and ensure a long-lasting repair. ### Tailored Fit For Your GM Truck or SUV This module is a direct-fit replacement for a wide range of popular GM vehicles, ensuring seamless integration.

It manages critical functions like fuel injection, ignition timing, and transmission shift points to ensure optimal performance, fuel economy, and emissions. **Is this module truly “plug and play”?** Yes! Because we program it using your vehicle’s specific VIN, it comes ready to install without needing a trip to the dealership for programming. In some cases, a simple security relearn procedure (often called a ‘CASE relearn’ or ‘Passlock relearn’) may be required, which can typically be performed by the owner following a series of key cycles. **How do I provide you with my VIN?** After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it’s essential for correct programming. **What if my original part number isn’t an exact match?** This module replaces several part numbers, including **19109040** and 9354896. As long as your vehicle’s make, model, and year are on our compatibility list, we can program this module to function perfectly in your truck. The VIN programming is what ensures compatibility. **Will this fix my harsh shifting transmission?** In many cases, yes. The PCM directly controls transmission line pressure and shift solenoids. If the module is failing, it can cause a wide range of shifting problems. This programmed replacement restores those factory settings, often smoothing out shift quality significantly. Please enter it in the payment notes and save to ensure we receive it. Orders without a VIN within our 2-business-day handling period may be canceled, as programming cannot proceed without it. ### Shipping - **Processing Time:** Reliably shipped within 2-3 business days. ### Warranty Enjoy peace of mind with a **one-year replacement warranty** on this part, effective from the date you receive it. Labor costs are not covered. If the part fails within the warranty period, we’ll replace it with a comparable unit or refund your purchase price, ensuring a hassle-free experience. **Return Address:** **Highway71autoparts** **9131 Highway 71 NE** **Spicer, MN, 56288**
