    Is what it is. 09 was a slug from day one and I got it brand new. When it finally ate a lifter at around 60000 miles it was the best day of my life lol... especially since I had gotten rid of it a couple months before that. Some are junk.. Some aren't.. it's the nature of assembly line products. I don't buy gas engine 3/4 tons and expect them to be race trucks... lol. Weighed the beast today too for fun.... full tank of fuel without me in it the truck is 6800 lbs... not bad.

    6 speed is your biggest change... the useless first gear in a 4L80e is basically like starting off in second gear with the 6L90e. First in an 4l80e is 2.48:1 and the 6 speeds first is 4.02:1 with a 2.36:1 second. Mechanical advantage is a world of difference along with a less power robbing trans. And the L96 makes more power.. stock anyhow. I think a lot of people would be happy with like L86 6.2s curve... makes more torque everywhere... but premium gas and longevity concern would be a no go with fleet buyers that account for a majority of gas engine hd truck sales. Simple, reliable and cheap...

    Yup...i get better mileage so far than the complaining I read about on here. Power is good.. my 09 was the same configuration and 3.73 and it was a gutless sack.. this truck is not. Driven plenty of 4.10 geared ones and felt they were as gutless as my 09... its more if you get a good one than anything else. I didn't buy it to haul heavy or to tow... I bought it because in my work environment these trucks last with minimal maintenance

    Yup... and it's a zero dollar option... aka it didn t actually cost a cent. I couldn't really care less that it has 3.73s... in this truck so far I honestly prefer it.

    3.73 is still available on the 2500HD trucks in 2017 with the 6 liters... I own one lol. It's just not the standard gear anymore and not usually a lot truck.. Like how 4.10 used to be. It won't make the drastic difference the guy complains about anyhow... Probably just got a dud or it has a binch of blow by and was made a dud from the start lol.
