It does matter.. If you have the MT6, you will naturally be getting crappier mileage than the AT5 since it's full time AWD.
My 2005 4Runner has the same V6 as the FJ and also a 5 speed automatic. Last month coming back through Vegas I was on cruise control at 70 mph the whole way. On 87 octane I calculated (total mile/total gallons) 20 MPG.
My rig is lifted and has sliders and heavier armor underneath. Stock roof rack and Bridgstone Revo tires too.
If you run agressive tires, a big cargo basket on the roof and heavily load the FJ your mileage will go down quite easily.
