I have a 99 dually 7.3 towing for the first time my trans. has 1,2,D & O.Drive going up hill on D 50 mph 2400 rpm and on the flat 55 mph is 2700 rpm with O.Drive on and on the flat 55mph 1700 rpm it has no power and it whants to down shift but if I go about 70 mph it feels good power but speed limit towing is 55 mph


any ideas
