First off I'm referring to a Duramax Allison combo. Is there any advantage to running say lower ratio in the rear end and higher in the trans say 4:56 in the rear and 4th gear apposed to 3:42 in the rear and 3rd gear in the trans. The final drive is close between the too with the first option being a little faster. Does one or the other offer better mechanical advantages.
