Buffydores,

If you are really wanting some gas mileage out of either of the transmissions you are thinking about, you can always add a "GearVendors overdrive unit". This would give you the mileage you want at the lower RPM's and the high speeds going down the road.

Just a thought, but all idea's come at a price.
