Any one know what the gear ratios will be for the updated allison in 2006? I am holding off on replacing my current truck thinking it will have a deeper overdrive , in turn getting better fuel economy running without a load! I understand the current model cant use full power in 5th gear with power adders and the chances are good that the new 6 speed will hold even less power in double OD but 90% of my travel is me and 800 lbs or cargo! the other 10% is hauling trailers in the mountains. :D
