So getting a better highway cruising gear would require it to be custom made, and I think the costs for that would be frighteningly high. Even if you get some company to make a few hundred sets, they can't get the cost as low as a differential which is already in mass production.
On ecomodder.com someone swapped their last gear and apparently it wasn't too bad to install, but it might be different on this transmission. That person's gear was I think made by taking 2nd gear from another transmission and flipping the cogs around to get a really low ratio, and since they had to TIG weld something on the gears I think the parts were weakened and so they failed after about 15k miles.

Ouch. Certainly not going that route. Best that can be hoped for is that this same transmission housing is used in several different iterations and a different iteration has a taller sixth. I'm certainly not going to plug in a welded part into something as key as a transmission. Thanks for the info.
