Restore Your Truck’s 4×4 Capability Instantly
Do I really need to provide my VIN?
Yes, absolutely. Providing your Vehicle Identification Number (VIN) is essential. We use it to load the precise GM factory software for your truck’s specific options and configuration. This ensures 100% compatibility and true plug-and-play functionality, eliminating any need for dealer programming.
Is this part difficult to install for a DIYer?
Not at all. For most DIYers with basic hand tools, this is a very manageable job that can be completed in under an hour. The module is typically located behind the lower driver-side dash panel, making it accessible without complex disassembly.
What happens if I don’t program the module?
An unprogrammed TCCM will not work. It won’t be able to communicate with the transfer case, BCM, or other vehicle systems. Our service handles this critical step for you, so you receive a part that is ready for installation right out of the box.
Is this a new or a used part?
This is a high-quality, inspected, and tested used OEM part that has been programmed with the latest software. We ensure every module passes our rigorous functional checks before being shipped to you, offering a reliable and cost-effective solution compared to a new dealer part.
Will this fix my specific 4WD problem?
This module resolves issues directly caused by a failed TCCM, such as communication errors (U-codes) and internal circuit faults. While it’s the most common point of failure for the symptoms listed, always ensure your vehicle’s wiring and the transfer case encoder motor are in good condition for a complete diagnosis.
