They just use a different combo of the existing clutch packs in the 5 speed allison. Takes a different valve body and trans computer.

For the $1650 they want for it I don't know if 1.5 MPG is worth the money. For me it's not but if you drive alot it might be.

You also have to consider how much hwy driving you are gonna do. You will only be saving fuel while in 6th gear, all the rest of the gears are still just like the 5 speed.
