Can someone tell me if a programer changing the shift points can hurt the trans? I was told this only builds more pressure inside and might hurt it since more pressure is more stress. I pulled my dads camper with his 8100 and it felt like it slides in gears instead of a firm shift. He has the Hypertech in his truck but I was afraid to mess with the shift points. Is this not what the Tow Haul is for, or should I change them and to what. I was going to get one for my D/A but now I am confused on what to do or leave it alone???????
