Technically the 3rd gear position inside the gearbox is overdrive; and the shifter selector is reversed for 3rd and 4th. You still shift the standard H-pattern, butthe trans is shifting 1-2-4-3. This is necessary because 4th gear in a conventional 4speed is direct drive; what you get is 1st, 2nd, direct drive, overdrive.
Also; the factory shifter on a New Process 833OD was made by Hurst. If you can make it fit in your car, its a great shifter.
