Yes. It will lower it due to the following two reasons.
1. Larger tires = more weight for the car to push. For every 200lbs of extra weight that your car has to move the mpg is reduced by 1.
2. Larger tires (unless the vehicle is lowered) will raise the height of the vehicle thereby decreasing aerodynamics. The vehicle will sit up higher and have less aerodynamics and increased drag. Making your engine work harder and reducing mpg.

A bigger trans wouldn't change anything in fact it would weigh more and probably cause you to lose mpg. If the present trans doesn't have an overdrive, replacing it with one that does would increase mpg.

My research has shown that if you don't add bigger wheels and tires the gas mileage will stay about the same. Maybe at worst you might lose 1/2 of a mpg.

Does using taller tires have a negative affect on gas mpg?
usually, yes, considering that taller tires and/or bigger wheels weigh more and require more power to spin. the fact that one full spin of the wheel covers a fractionally larger distance due to higher circumference of the tire partially compensates for it. but only partially.
