I leave my truck in "Hi" gear,since my 2-speed switch cable binds half the time. I can start out in 2nd,on a hill,with no problem.(NO LOAD). Some will disagree,but (on a hill),if I start out in "Granny Hi",by the time I shift to 2nd,the truck is almost at a complete stop,anyway. One trucking company I worked for,set the trucks in "HI",then removed the button and cable! Too many guys that didn't know how to shift,would "blow" the rears! I LOVE the 2-speed for loads,though!
