4 speed od or 5 speed

I never has used that terminology. If a transmission has 5 forward gears, it's a 5 speed, regardless of whether 5th is an OD.........which it is.

Much like the 833 4 speed OD. It has 4 forward gears, so it's a 4 speed. It's not a 3 speed OD, because it still carries an 833 designation which designates it as a 4 speed.

I don't know if Chrysler ever made a 3 speed OD or not, but both GM and Ford did. 3 forward gears, but 3rd was OD. It stands to reason Chrysler did too, but I have never seen one. I have my hands on a few Saginaw (GM) 3 speed OD transmissions and seen one Ford.
