Well I had the 3/4 ton for 10 years and this truck since 2011 and no problems at all. If in tow haul mode the transmission stays in gear longer to get up to speed. I do use it for braking along with the engine braking mode . That's my experience.

I've been told the same. It does use more fuel,but I was told the last thing you want is the transmission lugging at low rpm in overdrive. It increases temperature of fluid. Why else would manufacture s put a tow/haul mode on a truck if it wasn't meant to be used.

I was told the same thing with every truck we've had.

We've been towing between 90 - 100 KMph (55 - 62 mph). Run into sway issues, so still working on getting everything dialed in better.

We have friends that used live in the Canadian Rockies. When we'd go out to visit them, they had told me while traveling through the mountains even without a load, the truck should be in tow/haul as to not burn up the tranny.

Agree.... It's there for a reason, I use it. I'm not worried about saving a few pennies of gas when towing. It's only money and you can't take it with you as my father always said!

I actually had someone tell me that the tow/haul mode will tear up your tranny faster. I'll try and get a reason and post back.
Does the engine brake only work in tow mode?

It works in both modes, but has a bigger effect in the tow mode.

You should have a T/H button on the console. My '11 is below the radio on the right. Just push the button in and when you touch the brakes it will activate the engine (jake) brake.
I don't see how the T/H mode will hurt your Allison. Besides the Allison being a beast I don't believe any manufacturer would put an option on a vehicle that would damage it.

I have a '14 GMC 2500hd with the Duramax and 3.73 gears. It's a crew cab and will mostly be occupied with about 450 lbs of humans and another 200+\- cargo. My trailer is a 3150bhd weighing at about 10k max.
Is there anyone out there with a similar set-up? Going to be mainly highway on the east coast, and PA can get pretty hilly, so I'll try and make up for that on the straights.
Depends on what you want. These diesels seem to have a sweet spot. For me and my 05 2500 HD D/A it likes about 1800 RPM HWY, about 60-62 MPH as I like to drive for fuel economy. You just have to figure out what you want and explore at what RPM does it for you. I live in SW PA in the Alleghenies and travel the Shenandoah Valley often.

You will find out your sweet spot. The truck and trailer will tell you. My old 29ft was at 72mph at 2100rpms. My current 35ft is 65mph at 1900rpms.

My truck easily pulls both at 80mph. But life is to short to have the stress level that high.

safety first and always.
