I'm pretty impressed with the ratios available on that transmission. I would say 2, 3 or 4, 5, and 7 are equivalent to most older 4-speed OD autos. 1 is an extra short creeper/launcher gear. Nice for 4x4's. 8 and 9 are extra tall. You guys always talk about how you wish you had that extra gear to get the rpm down on the highway. Well there it is.
