How do I identify my Chevrolet transfer case?

How to Identify Your Chevrolet Transfer Case
To identify your Chevrolet transfer case, you can follow these steps:
1. Check the assembly tag: Every transfer case has a metal identification tag attached to it. There are two major types of assembly tags on transfer cases: Style A and Style B. Style A tags have a series of numbers (and sometimes letters) in the line for “Ass’y No.” This is the unit’s assembly number. Style B tags are “tab style” assembly tags that contain similar information as Style A tags, but without clear line markings. The assembly number on the tag can help identify your transfer case.
2. Note visual identifiers: You will need to note several visual identifiers for your transfer case, including:
– Number of output splines
– Type of yoke (slip-on or bolt-on)
– Right or left-hand drive
– Presence of a speedometer drive
– Type of shift (manual or electric)
– Type and location of switches
– Number and location of speed sensors
– Whether it has a live shaft or extension housing
– Shift pattern.
3. Provide the VIN: If you don’t have access to the assembly tag or if it is missing, you can provide the full VIN of your vehicle. By providing the VIN, you can search for the assembly number of the transfer case.
Remember, there are 14 transfer case models for Chevy vehicles, each with multiple variations. So, it’s important to utilize the tag information and visual identifiers to determine the correct model and variation for your Chevy vehicle.
