Ford's managed to make that pretty confusing
The Black Diamond is kinda like a bottom line Rubicon, With Lockers, but without the 241OR transfercase.
But to get the "Advanced" transfercase with on demand engagement in the Black Diamond, you have to get the Automatic Transmisson, So I personally kinda ignored that.
The Bronco I want (though I currently have no plans to actually get one) Would be the Badlands, pretty much bone stock with the Manual transmission and 33" tires. That's the only way to get the good transfer case with the manual transmission, and the only way to achieve that actual 94.something to 1 Crawl Ratio Ford is advertising...
