Thanks for the feedback. You're right, the 6l80 with a 3.42 has OA ratios of 13.78, 8.07, 5.23, 3.93, 2.91, 2.29 wich means that 4th in a 4l60/3.73 falls between 5th and 6th in a 6l80/3.42. But you have a much lower 1st which from my experience I don't need. It seems that the extra gears of a 6l80 are wasted on lower first gears. I'm leaning toward the 3.08 and hoping for better MPG, but it may be too sluggish. Gona place my order tomorrow, not sure which way to go. Thanks again!
