Do I need to take this part to a dealer for programming?
No. This is the main benefit of our service. We program the module to the VIN you provide before shipping it. This allows for a true plug-and-play installation without any need for dealership tools or software.
How and when do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive and program it with your VIN.
Is this a guaranteed fix for my ‘Service 4WD’ light?
The TCCM is the most common point of failure for the issues described.

This 2007-2014 Silverado 2500 Transfer Case Control Module is the correct component for these symptoms.
Will this fit my truck if it’s not a Silverado 2500?
Yes, this module fits a wide range of GM trucks and SUVs from 2007-2014, including the Sierra 1500/2500/3500, Suburban, Tahoe, and Yukon. Please carefully review the detailed fitment list in the description to confirm compatibility with your specific year, make, and model.
What if my original part number is not on the compatible list?
The part numbers listed are the most common compatible ones. However, GM often uses several different numbers for the same part. If your number is not listed, please contact us with your VIN, and we can verify compatibility for you before you order.
