Given a stock 4L60E calibration... what pressure or pressures would you adjust? For overall durability. Not for economy or for gentle shifts which GM called sales shifts, you know the big 1,2,3 sssslllluuuusssshhhh feel of a Caddilac. I like to feel a trans shift. But I do not like to feel it bang. I'm not asking for shift feel, I'm asking for overall safe improvements!
