Considdering the car wasnt ordered with different gears and they havent been swapped it 'should' have a 2.73 rear gear and the 700r4 has a .7 OD

Re: MPG?
Mine's on an average 15mpg city, 18-19mpg freeway. With the way my tank is though, im going to need a new gas tank and new fuel lines. But still thats good enough for me. Thats as much as my 03' Jeep gets.
