On the Chev & GMC sites, it lists the axle ratio as 3:42. Seem odd that they would go numerically lower, especially when I believe Ram offers 4:10.
Does anyone have a comparison chart of final drive ratios with the 3:73 axle and Allison 6spd comapared to the 3:42 and trhe Allison 10 spd?
The engine is already turning such low RPMs at reasonable interstate speeds, where will it run with this new combination? Does the computer lock out some of the gears in the trans when in tow-haul mode?
I got to see a GMC 2500 up close at my local dealership over the weekend. Looks like a beast of a truck!
