In an automatic the Od allows the transmission to use all forward gears (1st, 2nd, 3rd, 4th) using the 3 position allows the transmission to use gears 1 through 3 and no overdrive(generally recommended for towing). the second gear position allows the transmission to use gears 1 and 2 good for slowing on a hill with a heavy load or trailer. The !st position allows the transmission to use only first gear, ideally for stopping or slowing a heavy load. Shifting into a lower gear will not downshift the trans instintaniously. the transmission will shift down when conditions are ment. But, the trans cannot upshift past that point.
