How do I know what transfer case I have in my Silverado?
If you own a Chevrolet Silverado, knowing the type of transfer case in your vehicle is important for maintenance, repairs, and upgrades. The transfer case is a critical component that distributes power from the transmission to the front and rear axles, enabling four-wheel drive functionality. This article will guide you through the steps to determine the transfer case in your Silverado.
Identifying the Transfer Case
The easiest way to identify the transfer case in your Silverado is to look for the identification tag or label on the transfer case itself. This tag will typically display the make, model, and other key details about the transfer case. The location of the tag may vary depending on the specific model year and trim level of your Silverado.
- Locate the transfer case, which is usually found underneath the vehicle, between the transmission and the rear differential.
- Carefully inspect the transfer case for any identification tags or labels.
- The tag may be located on the side, top, or front of the transfer case.
- The information on the tag will likely include the manufacturer, model number, and other relevant details.
If you cannot find an identification tag on the transfer case, you can also try to identify it by the physical characteristics of the unit, such as its size, shape, and the number of gear shifters or levers.
Common Transfer Case Models in Silverado Trucks

Knowing the specific transfer case model in your Silverado can help you determine the appropriate maintenance, repair, or upgrade procedures for your vehicle.
Consulting Your Owner's Manual

The manual should provide detailed information about the transfer case, including the make, model, and any other relevant specifications. This information can be invaluable when it comes to maintaining, servicing, or upgrading your Silverado's four-wheel drive system.
