Put a two speed computer control 2 speed rear end in it

Seems simpler to keep all the gears in the transmission. Heavy (aka real) trucks don't use 2 speed rear ends much if at all anymore except for off road applications like dump trucks. A few years ago I drove a truck with an 18 speed box and 2 speed rear ends. That's a lot of gears, but I digress. :)
