C4 shift points

The c4 in my 73 F100 shifts very sluggishly. I installed a new modulator valve and adjusted it in and it still shifts very fast. Shifts to third at about 10-15mph.
What do I need to do to make it hold shifts longer since the modulator didn't make a difference? The fluid looks ok but I guess it won't hurt to change it and the filter.
Would adjustment of the bands make any difference? Im so tired of the way it shifts right now, its very anoying. Thanks for any help.
