Default Automatic Transmission Programming

Is there a way to program the 6-speed auto to skip gears during upshifts? So you could go straight from 1st to 3rd without hitting second?

My dad says that he heard something about that being possible.

it would cause alot of stress on the trans and would cause the motor to lug horribly.....

My truck got around fine with 3 gears and half as much horsepower...

Six strikes me as too much for unloaded driving. It does shift responsive enough to be palatable, but it still spends a lot of time shifting.

It'd probably save a bunch of wear on the bands. I don't see what you'd be severely stressing if you were unloaded.

ofcourse i know you are talking about a unloaded truck but when im towing my converter shudders when my pull truck is on my trailer. i have to keep it paddle shifted down to keep it from doing it. the h&s overdrive tune keeps it shifted down and adds line pressure. with 3.73 gears the tuner wont shift into 6th until it gets to 55 mph. i dont have the h&s though. if you could get them to build you a custom tune they could but they wont.
