Frequently Asked Questions
What is a TCCM and what does it do?
The Transfer Case Control Module (TCCM) is a small computer that acts as the brain for your vehicle’s four-wheel-drive system. It takes input from the selector switch on your dash and commands the transfer case motor to shift between 2WD, 4WD High, and 4WD Low.
Is this part truly plug-and-play?
Yes. The critical step that normally requires a dealership visit is programming the module to the vehicle. We perform this service for you before shipping. Once you receive the part, you simply need to disconnect the old module and connect this one. No further programming is required.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard, visible through the windshield.
How do I know if my TCCM is the problem?
Common signs include a “Service 4WD” light on the dash, inability to switch 4WD modes, and blinking selector lights. A professional scan for TCCM-specific trouble codes (like C0327) is the best way to confirm the diagnosis. This Programmed 24240487 Transfer Case Control Module is the most common solution for these symptoms.
What happens if I install a module that isn’t programmed?
An unprogrammed TCCM will not communicate correctly with your vehicle’s other computers. The 4WD system will not operate, and you will likely have persistent warning lights on your dash. Our pre-programming service eliminates this entire problem.
Which vehicles is this module compatible with?
This module fits a wide range of 2007-2014 GM trucks and SUVs, including the Silverado, Sierra, Suburban, Tahoe, Yukon, and Avalanche. Please check the detailed fitment list on this page to confirm it matches your specific model and year.
