I have one of the 4 speed OD units and it is just fine if all you are going to do is cruise cause you sure can't speed shift it. It is what I call stiff.
I have never driven an 833od car or truck that could be shifted fast, a lot of spread 1 to 2, third is actually 4th, and 4th is a down shift.
They are ok if you are just going to idle around looking cool, but it sounds like you are shifting a truck with the ratio spread.
