4 forward gears=a 4 speed. The Chrysler 833 transmissions were all called 4 speeds from Chrysler. They all carried the 833 designation, whether over drive or not. 833=4 speed. You don't call an A500 or A518 a "3 speed over drive". They are 4 speed transmissions. 4th gear (high) happens to also be an over drive.
