FACT... the 700 is an expensive tranny to rebuild or, build up. Even so, they don't like to be lugged around. A BB with torque can produce low rpm grunt that ravages a 700. No towing or snow plowing. Gear low enough to treat your overdrive like 4th gear. Don't think you can lug in overdrive on the highway. A 700 is perfect for a 1/2 ton short box. Don't hang them under a heavy truck.
