This pre-programmed solution changes everything for the DIY mechanic or independent shop. It puts the power back in your hands, saving you hundreds of dollars and significant downtime. It’s the smartest way to fix your 4×4 system, period.”

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the module to function in your vehicle.
Is this part difficult to install?
No, this is a very straightforward installation for most DIYers. The TCCM is typically located under the driver’s side of the dashboard, to the left of the steering column. It’s held in by a few bolts or clips and has several electrical connectors. No special tools are required, and the process usually takes less than 30 minutes.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases where the TCCM is the root cause, yes. This module is the central computer for the 4×4 system. Replacing a faulty one with our correctly programmed unit will resolve the communication errors that trigger the warning light.
What happens if I install it without programming?
An unprogrammed TCCM will not work. The vehicle’s other computers, like the BCM and ECM, will not be able to communicate with it, and your 4WD system will remain inoperative. Our pre-programming service is critical to making this a successful repair.
Does this fit models other than the Silverado 1500?
Absolutely. This module is compatible with a wide range of GM trucks and SUVs, including the Sierra 1500/2500/3500, Suburban, Tahoe, Yukon, Yukon XL, and Avalanche within the specified model years. Please refer to the detailed fitment list on this page to confirm compatibility with your exact vehicle.
