Bill beat me to it. No Rubicons had an NV1500, that was behind the 4-cyl
engine. The standard '07 Wrangler has (will have) the 241 transfer case, but
not 4:1 ratio IIRC; in '04 only the Rubicon had a 241.

Pennzoil Syncromesh is formulated for New Venture transmissions and is
cheaper than the dealership oil.
