Found some more info on the gearbox. It looks to be a Getrag 7MT1550, which is rated to 442 ft/lbs. Gear ratio's haven't been announced, but this trans supposedly covers a gear ratio spread of 11, so assuming an overdrive of .65, the crawler gear ratio gear could be up to 7.15 to 1.
Assuming this is going to have the same t-case as the current ranger, which I believe has a 2.717 low range ratio, and a 3:73 axle ratio... the crawl ratio on this would be 72-ish to 1. With 4:11 rear gears, the crawl ratio goes up to 80-ish to 1. For comparison, a new jeep rubicon is 82:1 I believe, so this may be in the same ballpark.
