Computer can be re-programmed for the gear change to adjust shift points, and speedometer change.
I'd really want more engine myself, but 3.73 is a good axle ratio for towing while maintaining some "highwayability". Although I'd be wagering a guess that guys towing on 3.73 gears have a bit more grunt under the hood. Otherwise 3.90 or 4.10 may be in your future.
