If first gear isn't low enough mileage in town will suffer with rear axle ratios like 2.35 / 2.37. That's why the OD trans -- you can have a low enough axle for good take-off/towing capacity and still get good highway mileage. To high a gear will hurt mileage more than help. A lock-up torque converter is a must. The best bet is a manual overdrive, of course!
