Expert Insight: The Brain of Your Workhorse
The late 90s GM trucks and SUVs are legendary for their durability. The heart of that reliability is the simple, robust Vortec V8 engine, but the brain is the PCM. It controls everything from fuel mixture and spark timing to transmission shift points. When it fails, the entire system is compromised. Unlike other components that wear out mechanically, a PCM failure is an electronic issue that can mimic dozens of other problems. Installing a properly programmed, high-quality replacement like this 1999 Tahoe PCM 09355699 is the single most effective way to ensure another 20 years of dependable service from your trusted vehicle.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the main computer in your vehicle. It controls all aspects of the engine’s and transmission’s operation to ensure optimal performance, fuel economy, and emissions. It’s essential for your truck to run correctly.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is specific to your vehicle.
Will I need to do anything else after installing this module?
In most cases, no. This module is sent ready to install. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions for this simple procedure can be easily found online for your specific model.

Please check the extensive fitment list on this page and match your original part number to one of the compatible numbers listed (09355699, 16250279, 09366810). Providing your VIN for programming is the final step that guarantees compatibility.
