How do I know what Chevy transfer case I have?

Determining the Chevy Transfer Case Model
To determine the specific transfer case model in your Chevy vehicle, you can follow these steps:
1. Check the assembly tag: Look for an assembly tag on the transfer case. There are two major types of assembly tags: Style A and Style B. Style A tags have a series of numbers and sometimes letters in the “Ass’y No.” line, which indicates the unit’s assembly number. Style B tags are tab-style tags that contain similar information as Style A tags but without clear line markings.
2. Use the VIN: If you don’t have access to the assembly tag or if it’s missing, you can provide the full VIN of your vehicle. By providing either the assembly number or the vehicle’s VIN, you can ensure that you are getting the right transfer case for your Chevy vehicle.
3. Visual identification: You can also visually identify the transfer case by comparing it to diagrams or images of different Chevy transfer case models. This can help you determine the correct model and variation for your vehicle.
It’s important to note that there are 14 transfer case models for Chevy vehicles, each with multiple variations. The two general-production manufacturers for U.S. transfer cases are Borg Warner Torque Transfer Systems and New Venture Gear Company, also known as New Process Gear Division of Chrysler. For Chevy models, you will be focusing on New Venture transfer cases.
Please keep in mind that these steps are general guidelines, and it’s always recommended to consult a professional or refer to the specific documentation for your vehicle to ensure accurate identification of the transfer case model.
I hope this helps you determine the transfer case model in your Chevy vehicle! Let me know if you have any other questions.
