Default Tow/haul Button whats it do?

So I know I should use this for towing and hauling (duh) but I was curious what does it technically do on a Dodge Ram. Has it changed over the years?

I'm also kinda wondering if is similar to ESP or something and if I engage it does it mean its easier for you to spin out the tires?

Basically is this a "fun button" of sorts?

Tow/Haul mode simply raises the RPM at which the transmission shifts for a given accelerator position, thereby giving better acceleration.

Nope, it's not a fun button per se...but it will keep the truck in a higher RPM when engaged and helps keep the RPM and torque up to give you more power when towing, especially over hills.

Here's some info from the 2007 Owners Manual:

When to use Tow Haul and O/D Off modes -

When driving in hilly areas, towing a trailer, carrying a heavy load,etc... and frequent transmission shifting occurs, press the Tow Haul O/D button once to engage Tow Haul. This will improve performance and reduce potential for transmission overheating or failure. When operating in Tow Haul mode, 5th gear is disabled and 2-3 and 3-4 shift patterns are modified. Shifts into OD (4th gear) are allowed during steady cruise and automatic closed throttle downshifts to 3rd gear are performed when driving conditions warrant for improved braking.

Pressing the Tow Haul O/D button a second time to select O/D OFF will disable 4th and 5th gear completely.

Your dash indicator light will indicate what mode you are in. You can release the modes with a third press of the button for full overdrive operation. An ignition cycle will reset the transmission mode to full overdrive operation.

I run in O/D off around town and only use full overdrive operation out on the highway at speed. I have used the Tow Haul mode as well, when towing, and it works as advertised. Mileage sucks but the engine is running at a higher RPM when Tow Haul mode is engaged so that's understandable.

I guess it could be a fun button around town in O/D OFF as the RPM's will always be higher vs. full OD operation. I do know I can get my truck sideways in O/D off on a wet street. The reaction by folks nearby when that MegaCab slides out is great to see.

It's a HEMI, don't need to O/D off to get sideways on dry pavement.

I like the tow/haul mode even when not towing. It stays in top gear until the speed drops to 40 mph then shifts down, shifts up when I touch the throttle. This is great on steep descents like the Siskyou on I-5.

BS...ever see how LONG a MegaCab is and how wide a 285 tire is? Takes OD off and 2nd gear...LOL

Oh you got that right. I've hauled over those a time or two.

That's because people aren't used to seeing a Living Room with wheels to begin with. Let alone sliding sideways down the road.

is it normal that on my 05 the tow haul button only does just that and doesnt feature the O/D off feature. Reason I ask is that if I push the button a second time like stated above it just shuts the tow/haul mode off and on.

I think my 04 is the same too. Thanks for that write up though MadDog, tried to rep ya but I guess I don't spread it around enough

Maybe need to hold the tow/haul button down? I'll try this.
