3 speed tranny swap

hello to all. i am new to jeep forum and therefore have many questions. my main concern now is gas mileage. i have a 92 4.0 with 3sp auto. at 65 to 70 mph my tach is over 3000 rpm! I'm running 35" tires and 4.56 gears for mud. its got great pickup and pulls 4 ever! I'm wondering if anyone has suggestions for swapping the 3 spd auto for a 4 spd auto or 4 w od. does a transmission exist that would be a direct swap. or would it be best to live with it? Performance is not an issue but mpg is killin me! I have a long ride on the 4 lanes to get to hunting and 4 wheeling spots in my area, any help will be greatly appreciated!
