4 speed od or 5 speed
To make this more clear, A Chrysler A833 OD gearbox is a 4 speed that has been re-engineered so that the old 3rd gear is an overdriven ratio instead of underdriven. Then the 3-4 shift lever is flipped, so that when you put the shifter into "4" the gearbox is in the "old" 3rd gear position, now acting as "high" or OD gear
But the old school 3 speed overdrives were actually a 3 speed standard transmission.......with an electrically operated, separate module in the tail, providing the OD gear.......much like the OD Torqueflites are now
Here's an example of an old 3 speed + OD
