Good guestion, I am not sure how they work. I had a buddy machine two different governers. I just went by the Looks of the A/A transmission pictures. The one I tried shifted at 5200 RPM.

Now I just manually shift at 6200 or so. Ill be honest I dont know how they work or What to take off, of where. , But I do have Two different machined governers here that shift Higher than stock.

Sombody clue us in. What needs to come off where and what about the inner spring deal. mike
