2013 Ram 5.7

I tried asking this on the"other" forum and I got the usual crap. Story is that I have a X23b, I towed it with a ram with the 4.7 that struggled badly on hills so I upgraded.
How do you other Ram owners use this transmission? Manual is clear as mud. Do I just use tow/haul or do I manually lock out 6th? For the time being most of my towing will be in NY gently, rolling terrain with short but steep hills.
It will be a couple of weeks before I tow in order to get the 1k miles for differential wear in.

I hear your pain!! I had a hard time finding out. Although we don't have the same transmission, mine is 5 speed on the 2010 Ram Hemi, I was told to just push tow/haul and "forgetaboutit"

I would suggest that you engage the "tow/haul" mode whenever you are towing something. All it does is change the shift points up a bit to allow you to maintain torque while accelerating. You might also have an overdrive lockout button, as least we do on our GMC which will lock out the overdrive gear.

I do both depending on the driving conditions. Always use tow/haul, lock out overdrive gears as needed.

Trial and error is all you can do. In my 2003 Ram, I don't have tow/haul but I do get an O/D off button so I run in 3rd 1:1 gear. This kills my mileage a little but the truck pulls. Now with yours being the 6 speed and having a manual option, you will have to make sure the tranny isn't hunting for gears all the time. If it is shifting, it is slipping creating heat. If you find a comfortable gear to run it in where it isn't shifting, use it even if the engine revs are up. My Hemi runs all day long at 2700 - 3000 rpms towing and the tranny stays nice an cool. These Hemi's like RPM's!

Just took a trip to the mountains last weekend and pulled over some steep passes with out issue. Kept it in tow/haul mode all the time.

Use tow/haul for sure. I find with our diesel that towing in 5th gets us better fuel mileage and lower transmission temperatures.

I have a 2012 Ram 1500 with the 6 speed 5.7 Hemi I tow a 26Bh and have found that my truck prefers 4 th gear all the time i put it in tow haul and drop it to fourth, it gets better fuel economy in fourth then it does in fifth whiel towing.

Local Dodge tech who also pulls with 1500/5.7 suggested I engage TOW if transmission was shifting a lot or pulling in obvious TOW/on situations. Did about a 350 mile trip one way to Nashville area from Central Ill. and probably used TOW 25% of trip. Watched RPM's and don't think I was ever over 2200 RPM except a couple of times in TOW just west of Nashville. I did play some with the gear override selection with TOW off and RPM's were about 200 higher in 5th than 6th. Truck auto shifted to 5th climbing overpasses and just kept on trucking along. I may be crazy but it seems to me like everything seems to be easier and smoother after about 20-30 of travel time. I have only made 4 trips with it and am still playing to try to find when/if Tow or manual gear selection is needed. I will just try to do what is needed to prevent truck from lugging and get to a point where I can make a selection proactively. Camper max is 6500 lb. and probably running at around 5500 with 200 in back of truck and 2 passengers. Have been Happy so far. I am going to try 4th on next trip as suggested to check MPG.

I pulled 8000 lbs with a Tundra 5.7L, basically the same specs and was not a fan of T/H. For no reason I could understand, the truck would take on a life of it's own starting up a hill and I would find myself running 4000 RPM. I just gave up on it and locked out 6th gear and had no issues at all. The truck would run all day long 60MPH @2000 RPM in 5th gear. I now have a new F250 with the 6.2L and T/H seems to work like it's supposed to. The more I use it and the more I read about it, the better I like it. The advantage of T/H is that it also helps braking when the truck senses you are going downhill. I think that saves wear on your braking system. Now that I've seen all of this, I would use T/H, let the truck think for itself and see how it does. if it seem sluggish or does a lot of shifting on the grades you can always lock out 6th gear. I think running in 6th helps with fuel economy a little, but that's personal opinion and I have no numbers to substantiate that.
