I actually did that the other day in my Ram 2500 CTD helping a friend bove some furniture and I wasn't even in 4wd. Although I had to take off the traction control because it kept retarding the engine due to the back tires breaking loose just a little. Once I did that then it made it up no problems. I can go back to his house next week and get it on video if you want.
If one actually thinks a diesel with 800 lb-ft of torque cannot go over a curb because it does not have enough power then they are dumber than a box of rocks.
yea... I drive all winter long with "traction Control" off.. ranks right up there with ABS braking for uselessness.. traction control and ABS I guess is for people don't know enough to "drive according to the conditions".
I agree 100%. Give me a truck with manual t case, no abs, no traction control, manual hubs and the rest of the amenities of a new truck, save for the emissions, of course.... And I'd be happy.
Oh wait, that's what my 07 is except for the ABS and no free spin hubs.
I've gotten stuck more times due to traction control on the ice roads up on the North Slope, than I can count.
Whack one drift, punch it and watch the truck lose power to not spin the wheels and yer stuck!
Gotta admit stability control is pretty cool though. Can throw the truck into a slide and the computer takes over and puts you right back on course without even counter steering!ShinerBock wrote:

I believe that fellow needs a lesson or two or three on how to drive a 4WD pickup. This last February while attempting to cross a ice bridge in pitch black conditions at 4:00 am, my truck broke through the ice, seems sometime earlier water up stream of the bridge flooded over the original ice bridge then froze over. The layer of frozen water was about 5" thick. With all four wheels in the broken ice and about 8" of water I was able to back my truck up and out of the broken ice and water, that's 5" of ice over top of 8" of water... trick was simple... 4WD and in LOW. Because of the depth of water and the thickness of the ice above... some $1500.00 in parts later my truck and myself... tread lightly crossing ice bridges. I wish I had the old 2005 3500... with 6" of lift and 35" tires I could have made it to the other side easily.
P.S. My truck is auto 3500 4x4 with 3:42 gears and stock height with OEM size tires.
.... oh forgot to mention... I had to change my shorts as well. :o- Once again all the Ram guy's making up some kind of excuse why the truck won't go over a curb. The guy that owns this truck said he had it in 4hi and his foot to the floor...

I agree, I have always taken off easy then push the go pedal. There is a lot of stress applied right at the start.Bedlam wrote:

With the extra torque in the 2016 maybe the Rams will be able to climb over a curb.
Nope, can't get over curbs
That has more to do with an empty back end with the driven wheels and the heavy front end against the curb. Most the diesel trucks will just spin the rear tires unless you have a little momentum in 2wd or switch to 4wd.
I think that was staged. With the rear on gravel he should have been spinning the wheels.stro1965 wrote:
3.42 doesn't seem ideal for towing to me, but what do I know?
Looking at the rear gear ratio only is looking at only part of the picture. The current 800 lb-ft Cummins mated with the 68RFE with a 3.42 rear end ratio actually sends more torque to the wheels than a 4.10 rear ratio 2011 650 lb-ft Cummins 3500 dually that used a 68RFE as well .
Ram 2014 2500/3500 6.7L CTD SRW 800 lb-ft @ 1,600 rpm with 68RFE with 3.42 rear ratio
1st gear--800lb-ft x 3.23 x 3.42 = 8,837.28 lb-ft
2nd gear--800lb-ft x 1.84 x 3.42 = 5,034.24 lb-ft
3rd gear--800lb-ft x 1.41 x 3.42 = 3,857.76 lb-ft
4th gear--800lb-ft x 1.00 x 3.42 = 2,736.00 lb-ft
5th gear--800lb-ft x 0.82 x 3.42 = 2,243.52 lb-ft
6th gear--800lb-ft x 0.62 x 3.42 = 1,696.32 lb-ft
Ram 2011 3500 6.7L CTD DRW 650 lb-ft @ 1,600 rpm with 68RFE with 4.10 rear ratio
1st gear--650lb-ft x 3.23 x 4.10 = 8,607.95 lb-ft
2nd gear--650lb-ft x 1.84 x 4.10 = 4,903.60 lb-ft
3rd gear--650lb-ft x 1.41 x 4.10 = 3,757.65 lb-ft
4th gear--650lb-ft x 1.00 x 4.10 = 2,655.00 lb-ft
5th gear--650lb-ft x 0.82 x 4.10 = 2,185.30 lb-ft
6th gear--650lb-ft x 0.62 x 4.10 = 1,652.30 lb-ft
So looking at the big picture of how much torque is being sent to the rear wheels, if the 3.42 rear ratio is not ideal for towing then you would have to say that the 4.10 rear ratio DRW trucks mated to the 650 lb-ft Cummins from just 4 years ago are even less ideal.
Although Ford's 6R140 transmission is geared with shorter gear ratios in each gear making it send more torque to the rear wheels than even your current truck.- I would think all of us would take off easy to save the equipment when towing a fifthwheel. I always think when towing up a mountain I want the truck to do another mountain and not make this one the last one. I know I am old but walking sucks along any highway.

The CTD is a longer stroke than the PSD and requires less RPM to make its power. This was the hardest part for me to get used to after running a PSD for 10 years. My CTD runs with 4.44 gears and my PSD had 3.73 ratios. Since I rarely drive over 65 mph, I don't need tall gears and am happy with my current combination.
4.44 gears are pretty low which would give you higher revs than 3.73 gears.
What RPMS are you turning at 65?
I'm usually spinning under 2000 rpm at 65 mph in 6th gear on the Aisin. There are still grades I may climb in 4th with my 22k lb GCW, but those are usually twisting as they climb, so I am not taking them at 65 mph.
