Change from 4-speed to 3w/OD

The OD box has the same first gear as the 3.09 box and I use the 3.09 box. I don't understand how the split bothers anyone.


BTW, those who say it's a 4 speed overdrive are correct. It has 4 forward gears and it happens that 4th is direct and 3rd is overdriven.

4 speed overdrive is what it is.
