Shift Kit

if the plate doesn't sit flat between the VB top and bottom, in other words somethings caught and putting a gap somewhere it could cause a loss of fluid pressure in one of the channels not giving it enough to move the valve, I checked the VB for being straight and true and it is, not twisted or anything and the plate looks good too but I blanked out on filing the holes in the plate, wonder if any of those are causing an issue

Looks like I didn't adjust the line pressure vale plate 1 7/8 either. Well I've got a ton to go by now with that book, start running down the list.
