Recently i have been running my 700-r4 in 3rd gear instead of overdrive when im under 55-60 and i have been getting much better gas mileage. From about 6 to around 9-12. Seems to be lugging a lot less than it did when it was when it was in overdrive. Although i'm sure most people already know about this, i just figured i would throw it out there for the people that might not know. Just for reference my truck has a 4 inch lift and 33's.
