2012 2500HD CC SB with 6.0L and 3.73 ratio
Hi all,
Took our first long trip with my newer tow vehicle. I went from a 2006 chevy Duramax to a 2012 6.0L gas with the 3.73 ratio. Now I fully understood there would be a difference due to it being a gas so that is not my issue here. But with a 5100lbs dry travel trailer(estimated 6500lbs max loaded) , I am no where near the limits of the truck.
Well like I started off, too our first long trip, Central NY to Maine. Towing on the highway at 65mph it would not shift to 6th gear. Is this typical for this setup? I am strongly considering swapping the gear ratio to the 4.10 depending on the cost.
In 5th gear I got like 8.5mpg which is what I expected, transmission was nice an cool typical temps in the 170-180 range, peaked at 186 climbing the Berkshires on the Mass turnpike, absolute max I seen was 196 when we slowed to a crawl in a traffic jam, but that was maybe 10 minutes.
