Is Your Truck’s 4WD System Unreliable?
When you depend on your GM truck or SUV for tough jobs or navigating harsh conditions, a flashing “Service 4WD” light is more than an annoyanceโit’s a critical failure that compromises your vehicle’s capability. If you’re experiencing an inability to shift between 2WD and 4WD, grinding noises, or a completely unresponsive four-wheel-drive system, a faulty Transfer Case Control Module (TCCM) is the most likely culprit. Don’t let a bad module leave you stranded. This is the direct, reliable solution to get your truck’s core functionality back online.

Expert Mechanic’s Insight
From over 20 years in the garage, I’ve seen countless TCCM failures. They’re often caused by internal electronic component breakdown or voltage irregularities. Many people are tempted to grab a used module from a salvage yard, but this is a huge gamble. That used part not only has an unknown history but, more importantly, it isn’t programmed for your specific vehicle’s options and VIN. This leads to communication errors and a 4WD system that still won’t work. That’s why installing a Programmed GM Transfer Case Control Module 24242480 with the latest software is the most reliable path. It not only fixes the immediate problem but also ensures your system benefits from any performance and reliability improvements GM has released since your truck was built.
Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it to you. This makes the installation process straightforward, saving you time and the high cost of dealership programming services.
How do I provide my VIN number?
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 your VIN, as the programming is a critical part of the process.
How can I be sure this fits my truck?
Please review the detailed fitment list in this description. This module fits a wide range of GM trucks and SUVs from approximately 2007 to 2014. Matching your vehicle’s make, model, and year to the list is the best way to confirm compatibility.
My original part number is different. Will this still work?
Yes, most likely. This module is a compatible replacement for a long list of original GM part numbers, including 24261367, 12588096, 24239190, 24240487, and many others listed above. As long as your vehicle is on the fitment list, this module will function correctly.
