Did you put your fuel cap back on at the gas station?

If you selected the optional tow package...then you have 3:73 gearing if not then you have 3:21's.

Ive got 4:10 gears and a 6sp tranny. I get about 17 miles a gallon driving in the city and about 22 on the highway. Any idea how my mileage will be affected when I go to 35's later this month?

Now that I think about it I believe you are correct the Auto came stock with 3:73. I know the 6spd had the standard 3:21, tow package 3:73 but some 07 models with tow came with 4:10's

Auto's always come with 3.73

You can also get 6sp sports with 3.73's optional, even without the tow package. THats how my jeep is optioned. No tow package but 3.73's in a 6sp sport.
