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.

It would be interesting to know what the difference in gas mileage over a couple of tank fulls driving at highway speed would be w/ the 2 different ratios.

I'm sorry, but either you're doing it wrong or this is BS. I pull this TT and routinely pass traffic with it, on hills in the mountains no less.   Sent from my STH100-1 using Tapatalk

Our trailer weighs 10,8k dry. She runs all day long with plenty of speed. Will even hold the cruise control up Hill.   Sent from my SM-T800 using Tapatalk

My Dually weighs 7800 pounds empty with just me and a full tank, I weigh 185. With my double slide Arctic Fox I weigh more than 13000 pounds and I push a lot of surface area as Arctic Foxes are high u

if you are not towing, just hauling heavy stuff in the bed all day long, 3.73 makes more sense.

No it doesn't.

 

Just because you are turning less rpm does not mean you are using less fuel, it requires more throttle (fuel) at lower rpm to maintain speed.

 

Fuel usage will be the same but pulling power and downsifts will be better with 4.10's, I would order 4.55 gears if it was a option, the 6.0 is gutless in 5th-6th gear, would rather it turn some rpm and make some useable power.

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

I had an '04 w/ the 4 speed trans then went to the '11 w/ 6 speed. Not sure of the gearing, but a world of difference between the 2 trucks.

 

For my use I'm happy w/ the 6.0 L's power.

 

I wonder if the people that are unhappy would be happy if it was tuned from the factory to produce more HP @ a higher (unusable RPM) along w/ a narrow powerband?

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...

That's odd seems how your '09 had the EXACT same drivetrain including the same L96 6.0 and 6L90E, only difference is you '17 weights more then your '09 did...

My L96 is tuned and power wise there is not much if any difference, truck is a heavy pig, I have torque management turned completely off and tuned for max power.

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.

Some curious reading lead me here. Wondering if the original poster ever found an issue or if he is now happy with the truck. I currently own an 04’ 2500HD CCLB with the 6.0 and 4.10 gears. I tow my rock crawler on a double axle trailer weighing about 7k and also have a slide in camper in the bed that weighs 1200lbs. The truck does amazing. Granted, it drinks the fuel at 7.5mpg, but it’s also paid for. Did I mention it has over 530k miles on it?? 
 

I just wanted to echo again that these motors are not going to pull a grade or hold speed on even a small hill in the 2500rpm range. You are not going to hurt them by revving it hard, they’re made to do it. I go on trips once a month which are 4-7 hours from home and always having to cross mountains. Couple grades I pull are 5-7 miles long and I usually climb them at 3500-4000 rpms and have held it at 5000 a few times as well. It’s not a diesel, they make all their power up above 3500. Don’t be afraid to let it eat!!

No. The engine has been replaced once and the transmission twice. The fist motor went 350k. 
 

The truck drives nice and tight, straight, and handles very good. I recently had to replace the AC system. It spends its whole life towing basically. If I could figure out how to post some pics I would, but this forum is strange to me. I spend all my time over on NC4x4.com, I wound up here cause I’m thinking of buying a 26’ Gooseneck trailer that I can just leave my camper on the front of and pull the Jeep on. But I fear it may be too much for this truck to haul across the mountains, but I may try it anyway. Then I’ll just explain to the wife “looks like I gotta buy a bigger truck”

that's great.  I bought mine thinking I would never need to buy another truck, or at least that it would last 20 years.  I think it will.  Going to get a gas sipper for a daily and just count on my 6.0 truck to be there when I need it for many years.

I would agree.  The L96 was introduced in 2010 MY.

 I have a 2018 2500 with 4-10 gears and a 8 speed transmission. I live in north east Texas with flat ground. My RV weights roughly 6500 lbs and I cant run 70 with out thinking I am going to blow it up. This truck dont even like my 5000lb welding trailer. 

 It now has 15500 miles on it and I have tried every kinda gas they make .  It's been in the shop 3 or 4 time to see if something is wrong with it and they cant find anything.    Not happy at all with this pig

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
