[BFix] Thinking outload gas mileage and EB....

What kind of auto tranny cost that much?  Cuz honestly I really want to put
an AOD in the Bronco with a Stak 3 speed bronco box behind it.  Seems like
the ultimate dual purpose setup.  But I gotta think it will be at least 5K
to do the tranny and T/C.  Plus I would have to think an AOD would get
better mileage than an NP435, not that that's why I'm wanting to do it, it's
more of a driveability issue.
