There are two shafts in a transmission - an input shaft and an output shaft. The drive ratio is determined by the number of full turns the input shaft makes for each full turn of the output shaft. For example, if it took 1.5 turns of the input shaft for the output shaft to make a full rotation, you'd have a 1.5:1 ratio - this is known as underdrive, or gear reduction. If the input shaft made one complete rotation for each rotation of the output shaft, you would have a 1:1 ratio - this is known as direct drive. When the input shaft makes less than a full rotation for each full rotation of the output shaft, that's overdrive. For example, the fourth (overdrive) gear in a 4L60E transmission has a .70 overdrive ratio (i.e., .7:1), so it would make 7/10th of a complete rotation for each full rotation of the output shaft.
