The recommendation for city driving was to start out in second gear from a stop then let off the gas to change to 2nd & over. This was a form of semi automatic shifting that required the clutch only at stops. Hilly country like the Ozarks and other old mountain ranges don't lend themselves as well to that theory. If it requires lock out, then it would be a lot like having a transmission with no OD at all. The overdrive can then be used on longer trips if a person ever has an itch to do that. The planetary will last longer if it's locked out most of the time.
