Is a โService 4WDโ Light Ruining Your Drive?
There’s nothing more frustrating than seeing a warning light on your dash, especially one that compromises your truck’s capability. If your 2007-2013 Silverado, Sierra, or other GM truck is refusing to switch into four-wheel drive, getting stuck in a gear, or constantly flashing that dreaded โService 4WDโ message, your Transfer Case Control Module (TCCM) is the most likely culprit. Don’t let a faulty module sideline your vehicle. This is the simple, reliable fix that gets you back on the road and trail with confidence.

- Your 4WD selector switch lights are not working or are flashing.
- The vehicle is unable to shift into or out of 4-High or 4-Low.

Expert Insight: The Critical Role of VIN Programming
Many sellers offer used or generic modules, but they miss the most important step: programming. A TCCM that isn’t flashed specifically to your truck’s VIN can cause a host of new problems, from incorrect gear engagement to communication errors with other vehicle systems. It’s like putting the wrong key in a lock. Our process ensures the module communicates perfectly with your truck’s powertrain and body control modules, just as the original did from the factory. This is the key to a successful and lasting repair.

Frequently Asked Questions
Where 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 your order until we receive this information, as the programming is essential for the module to work in your vehicle.
Is this a difficult part to install?
For most DIY mechanics, this is a relatively simple installation. The TCCM is typically located under the driver’s side dashboard to the left of the steering column. It involves removing a few trim panels and connectors. Since our module is a programmed 2007-2013 Silverado 1500 transfer case control module, there are no complicated computer steps after the physical installation.
Will this fit my 2007 ‘classic’ body style truck?
No. This module is for the ‘new style’ (smooth door skin) GM trucks that began production in 2007. It will not work with the 2007 ‘classic’ models that retained the 1999-2006 body style. Please verify your body style before ordering.
Why is this better than buying a used one from a salvage yard?
A used module from a salvage yard will be programmed to the donor vehicle, not yours. It will not work correctly and will still require a trip to a dealer or specialized shop for expensive programming. Our module provides a guaranteed, pre-programmed solution that saves you that time, expense, and uncertainty.
How do I know if the TCCM is really my problem?
While the symptoms listed are strong indicators, a proper diagnosis is always recommended. Common culprits for 4WD issues include the selector switch and the transfer case encoder motor. However, if you have communication codes or the switch and motor have been tested and are working, the TCCM is the most common point of failure.
