the tranny has a "overdrive " button on end of shift which allows you to slightly down shift. I do use it going down grades but it is not enough to really slow you down enough without using bracks too much. So what I'm looking for is something like PAC BRAKE to help assist in controlling down hill speeds. Also this eats up brakes fast. Thanks for replies.
The Tow/Haul on the Torqueshift is simply a forced downshift built into the transmission--basically, the same thing you can do by manually downshifting with the lever. Not quite as good, as the variable vane turbo provides back pressure that your turbo won't-- but should help. With the 2002 year, you have a 7.3-- I have heard the exhaust brakes work very well with those engines.
