An Expert’s Insight on TCCM Failure
As a technician with over two decades of experience, I’ve seen countless GMT900-platform trucks and SUVs come in with these exact 4WD issues. The original Transfer Case Control Modules are often susceptible to failure from moisture intrusion, vibration, or simple electronic fatigue over time. The biggest mistake owners make is buying a used or blank module, only to find out it still needs to be programmed by the dealer, adding unexpected costs and delays. This Programmed Transfer Case Control Module 24242480 is the smartest path to repair. It bypasses the dealership headache entirely and ensures you’re installing a unit with the most current software, which often corrects the very glitches that caused the original to fail.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we receive your VIN, as the programming is essential for it to function correctly in your vehicle.
Is this installation truly plug-and-play?
Yes. Because we program the module to your specific VIN before shipping, it is ready to be installed without any further calibration or dealer intervention. Simply disconnect the old module and connect this new one. In most vehicles, it’s located behind the lower dash panel on the driver’s side.
Will this module fit my vehicle?
This TCCM is compatible with a wide range of GM trucks and SUVs from approximately 2007 to 2014, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Avalanche. It replaces numerous part numbers, including 24242480, 24261367, 12588096, and more. Please review the detailed fitment list on this page to confirm compatibility.
Will this fix my ‘Service 4WD’ light?
In the vast majority of cases, a faulty TCCM is the root cause of the ‘Service 4WD’ warning. While this part is the most common solution, we always recommend a proper diagnosis to rule out other potential issues, such as a faulty transfer case encoder motor or selector switch.
What if I install it and it doesn’t solve the problem?
Our module is guaranteed to be programmed correctly and function as a new unit. If your 4WD issue persists after installation, it indicates the problem may lie with another component in the system. This unit is backed by our one-year replacement warranty, covering the part itself.
