Restore Your Truck’s 4WD Capability Instantly
Is that frustrating “Service 4WD” light glaring at you from the dash? Are you unable to switch between 2WD, 4-High, or 4-Low? A failing Transfer Case Control Module (TCCM) is often the culprit, leaving your capable truck or SUV stuck when you need its four-wheel-drive system the most. This isn’t just an inconvenience; it’s a loss of the core capability you depend on. This direct-fit TCCM is the definitive solution, arriving at your door pre-programmed to your vehicle’s specific VIN. Forget the expensive dealership visit and the hassle of programming—this is a true plug-and-play fix to get you back on the road and trail with confidence.

Expert Insight: The ‘Why’ Behind Programming
From over 20 years of hands-on diagnostics, I’ve seen countless truck owners get stuck in a repair loop. They might buy a used TCCM from a salvage yard, only to find it won’t work because it’s still programmed to the donor vehicle’s options (axle ratio, tire size, etc.). The vehicle’s main computer rejects it, and the 4WD remains inoperative. That’s why our VIN-programming service is so critical. We ensure the module you receive is a perfect digital handshake for your specific truck. It’s not just a part; it’s a complete, tailored solution that respects your time and money.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
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 specific to your truck.
Will this fix my “Service 4WD” light?
In the vast majority of cases where the TCCM is the root cause, yes. This module is the brain of the 4WD system, and its failure is the most common reason for that warning light. However, we always recommend a proper diagnosis to rule out issues with the transfer case encoder motor or the dash switch.
Is any other programming or calibration needed after installation?
No. Because we program the unit to your VIN before shipping, it is ready for immediate installation. Simply disconnect the battery, swap the old module with the new one, reconnect the battery, and your 4WD system should be fully operational. No relearn procedure is required.
My original part number isn’t 24240487, but it is on your compatible list. Will this work?
Absolutely. GM uses many different part numbers for the same component over the years due to minor updates or supplier changes. As long as your original part number is included in our compatibility list in the description, this module will function as a direct replacement for your specific 2008-2013 Silverado 1500 Transfer Case Control Module or other listed vehicle.
Where is this module located on the vehicle?
On most compatible GM trucks and SUVs, the Transfer Case Control Module is located behind the dashboard on the driver’s side, to the left of the steering column. It is typically a black box with two or three electrical connectors.
