What kind of transfer case in a 2 door Chevy Tahoe?

A 2-door Chevy Tahoe doesn't exist. The Tahoe has always been a 4-door SUV. Therefore, there's no transfer case specification for a nonexistent vehicle.

If you're thinking of a different Chevy SUV (like a Blazer, perhaps?), or if there's a model year or trim level you're interested in, please provide more details. Then I can give you the correct information on the transfer case.
