No tow/haul mode on 2014 JGC Overland 5.7Hemi ?

So, I have just taken delivery of my 2014 Overland after trading in the 2011 Overland LEMON I have been dealing with for 2 years. . . .

What I noticed is that there is no tow/haul button in this version. In the past I know they have been left out of the 6 Cyl. But seeing as this has the 5.7L Hemi I was under the distinct impression it should either have the button to at least an option to switch into tow mode somewhere in settings.

There is NO mention of a tow/haul mode button or setting anywhere in the new vehicle documentation. . . . . am I missing something?

My 2014 Overland Hemi doesn't have tow/haul mode either. I figured with an 8 speed trans it has enough gears to choose from and it should adapt to the load as needed.

Paddle shifters probably on reason tow haul removed.

I thought of that. . . . but the 2011 had tiptronic tranny too. . . just no paddle shifters. I have a call into Exec. Relations to get an answer.

The 2011 6 speed had an entirely different transmission (V8 with a tow/haul mode, V6 without) than the 2014 8 speed. I dunno but I suspect the new 8 speed transmission does not have a specific tow/haul mode.

Being it's a beast to begin with, it's probably in full-time tow mode

AFAIK, the only thing the tow/haul mode button does is tell the transmission to use shift points appropriate to heavy loads. I think the newer transmissions are smart enough to figure out you've got a heavy load based on speed/torque/etc, so they can adjust automatically. So the mode button isn't needed any more.

The ZF tranny is a self learning/adapting transmission and will adapt to driving style and loads. So when you have a trailer hooked up it automatically realizes that and holds gears longer, etc. - even in Eco mode, no need to even disable that.

It's kind of cool, after you unhook the trailer it will hold gears longer for a few miles before it realizes the load is gone and goes back to shifting normally. Put the trailer back on, realizes its right away and holds gears. Really a great transmission for towing.

So I got my response from Chrysler Exec. Relations, who said that the only JGC's equipped with a "Tow/Haul Mode" button are those with Towing packages that have the Adaptive Cruise Control (ACC) & Front Collision Avoidance (FCA) features in the Advanced Technology Package.

When explaining what it did they advised that the only function is to disable the FCA and ACC features when towing and that it does nothing to effect tranny function as the new 8-Speed Tranny adapts automatically.

I have read elsewhere, I forget the source, that Jeep recommends tranny sport mode for towing, as it changes the shift points.

Interesting. Their statement must imply exclusion of the SRT. My 2014 has the ZF 8 speed, and it has the tow package plus ACC. It does have a "Tow" mode, which does additional things. (I haven't explicitly tried the ACC while in "Tow" though.)

When I put it into Tow, it changes the front/rear split to 50/50, it fully closes the damper valves in the shocks so they're at their firmest, it noticeably shifts differently, and it seemingly reduces accelerator sensitivity.

Anyone else here this? Any idea where it was sourced from?

Now that has me a bit worried, as it seems to contradict what I was told by Jeep HQ regarding the 8SPD and tow mode functionality. . . . . . Do you have an excerpt or page reference from the user guide by chance?
