904 Governor Replacement

is the one I took the tail off three times to get the governor right. lol.

Op
The KD can only do so much, even if you crank up the line pressure.
If you're gonna keep the auto upshift feature, then the governor is gonna need fine tuning. and if you swapped out your rear gears, for say 15>20% more, then, there's no way around it. Which is why most guys just throw in the towel, and go to a full-manual. (no slur on on you, 4mulas, nor anyone else) , that's just how it is.

But I gotta tell ya, a well tuned governor in a semi-auto, with a working PT downshift, and a higher than factory stall convertor, all together, is a dream come true. So, so, much fun.
Wait @AJ/FormS when you say “full manual” are you talking 4 speed 833 type or a manual shift on the 904 trans like a drag set up?
