What's the absolute maximum range of your Duster?

Piggly Wiggly? I'll be stopping at our Piggly Wiggly today. The O/D works better with lower gears, 3.55 or 3.91. That keeps the ratio around 2.76 which is a nice highway gear. O/D is highway cruising gear. Use it like a 3 speed until you hit the highway.
