6.2l Blazer mileage

I have 12.5x33 tires. No lift on it. I plan on lifting it, but have not done so yet. Anyway, I wouldn't think that 33" tires would be big enough to hurt the mileage that bad. As another question, is there any difference between the transmissions for the diesel vs gas, or is a 700r4 a 700r4?

Well, I have determined that my speedo is off by almost 10 mph so I have been driving on the highway at almost 80 when I thought I was running 70. After slowing down a little and adjusting for the mileage diff my mpg is now a more liveable 14-15. Still a little lower than I wanted, but much better. Maybe I will slow down a little more and see what happens!
