I'm on the horns of a delima...which ratio? My Wrangler is a 2000 with a non overdrive automatic with lockup converter. Tire size is 32.7 inches in height. I do some beltway driving but mostly inner city with occassional trail riding. I've looked at grimmjeepers gear calculator but my concern is sustained high rpm on the beltway. Does the 4.0 have any issues with sustained 3000-3500 rpm? I've never thought of them as hi revvers...
2000 Wrangler TJ, 4.0 6 cyl, A/T, 3.07 gears...ugh.
