700R4 no fourth

I just rebuilt a 89 700R4 standard clutches and steels but 13 vane pump and the super 2-4 servo pistons. Shifts good lockup in 3rd but no fourth neither auto or manual shift. What could be the problem? I've had it up to 60, but it still doesn't shift to fourth. I changed the governor that did nothing diff.Thanks

you have the super servo setup incorrectly i bet.


the 2-4 servo is multi stage , incorrectly setup aftermarket servo & the pin cannot apply the band in OD since a different piston does the apply pressure for OD than for 2nd gear.

I resigned my mod position and seldom visit the site here. I am sure the other tranny pro's are still around . Perhaps real busy with work?
