An Expert’s Note on Programming
“Many people try to save a few dollars by pulling a module from a salvage yard, only to find it doesn’t work. That’s because a TCCM is not a ‘one-size-fits-all’ part. It’s coded to the specific options and powertrain of the original vehicle. Without proper programming to your truck’s VIN, it simply won’t communicate correctly with the BCM and ECU, leaving you with the same problems you started with, plus a wasted afternoon. This pre-programmed module removes that entire gamble, giving you a part that is guaranteed to work right out of the box.”
Don’t let a small electronic module sideline your powerful truck. By choosing our programmed 2007-2014 Silverado 3500 TCCM, you’re not just buying a part; you’re buying a reliable, professional-grade solution that restores the full capability and dependability you expect from your vehicle.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply 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 essential for the part to function correctly.
Is this a simple plug-and-play installation?
Yes. Because we program the module to your VIN before shipping, the installation is a direct plug-and-play process. In most cases, it involves disconnecting the battery, removing the old module (typically located on the driver’s side of the dashboard), plugging in the new one, and reconnecting the battery. No special tools or dealer visits are required.
What happens if I install it without providing a VIN?
The module will not function correctly. It must be programmed to your specific vehicle’s configuration to communicate with the other onboard computers. We require the VIN to ensure you receive a fully functional part.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases, yes. A faulty TCCM is the most common cause of the “Service 4WD” light and related 4×4 engagement issues in these GM trucks and SUVs. This part is designed to be the direct solution for that problem.
How is this different from a part from the local auto parts store?
Most modules from local parts stores are sold “blank,” meaning they still require a trip to a mechanic or dealership with expensive scan tools for programming. Our module arrives ready to install, saving you that significant extra step, time, and expense.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself. If the part fails within one year of the purchase date, we will provide a replacement.
