When I traded up from my 2003 GMC 6.0L w/4 speed and 3:73 RE, 210k miles, I was looking for the 6.0L again and the 3:73 ... in 2015, no luck, only 4:10. Altho, I surely believe now after hauling my TC the 6 speed and 4:10 is a much better rig.
If I had that choice over, I'd pick the 4:10 as it hauls much better, AND I still get as good gas mileage as did the 3:73. Of course, the engineering is different, but that newer set up is nice. Got 53k on this one, no issues, and hope to get that many miles out of it again.
Was at one point thinking 2020 new, but changed my mind after last trip, and will stick with this one awhile longer. Plus, just put new shoes on it :)
