is there a easy way to bump up the pressure in a 400 tranny or will i need to get a kit to do it. i seem to have a nice shifting tranny now but it seems very smooth in a light car you can hardly tell its shifting . i have adjustable modulator now and i have them spaced pretty good but the tranny shifts so nice that you can hardly feel it. i dont have the electriid kickdown hooked up as i dont need it with the car.
