Is there any detriment to running in Tow/Haul mode or with the exhaust brake on at all times? I like the shift points better on tow/haul and I like the braking effect of the two combined even when not towing. And I'm sure it saves the brakes. Anything wrong with running like that all the time?

 

This should have been included in your owners manual.

When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting occurs, press the TOW/HAUL switch to select TOW/HAUL mode. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, transmission upshifts are delayed, and the transmission will automatically downshift (for engine braking) during steady braking maneuvers.







TOW/HAUL Switch


The “TOW/HAUL Indicator Light” will illuminate in the instrument cluster to indicate that TOW/HAUL mode has been activated. Pressing the switch a second time restores normal operation. If the TOW/HAUL mode is desired, the switch must be pressed each time the engine is started.

Warning!
Do not use the “TOW/HAUL” feature when driving in icy or slippery conditions. The increased engine braking could cause the rear wheels to slide, and the vehicle to swing around with the possible loss of vehicle control, which could cause an accident possibly resulting in personal injury or death.



Torque Converter Clutch
A feature designed to improve fuel economy has been included in the automatic transmission on your vehicle. A clutch within the torque converter engages automatically at calibrated speeds. This may result in a slightly different feeling or response during normal operation in the upper gears. When the vehicle speed drops or during some accelerations, the clutch automatically disengages.

Note:

The torque converter clutch will not engage, and the transmission will not shift to sixth gear, until the transmission fluid and engine coolant are warm [usually after 1 to 3 miles (1.6 to 4.8 km) of driving]. Because sixth gear is disabled, and engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting properly when cold. This is normal. Using the Electronic Range Select (ERS) feature, when the transmission is sufficiently warm, will demonstrate that the transmission is able to shift into and out of Overdrive.
If the vehicle has not been driven for several days, the first few seconds of operation after shifting the transmission into gear may seem sluggish. This is due to the fluid partially draining from the torque converter into the transmission. This condition is normal and will not cause damage to the transmission. The torque converter will refill within five seconds after starting the engine

 

That's a lot of information, and I certainly appreciate it, but it doesn't really answer my question. What I'd really like to know is is it detrimental in any way to run in tow/haul with the exhaust brake on all the time? I like the shift points better as well as the engine braking and I'd prefer to run that way. Just not if it's bad for the truck in some way.

 

Won't hurt a thing I run my 2012 that way all the time. Drive it and enjoy.

I too prefer to run mine this way. They play really well together and the benefits are great. I don't see it hurting anything but it sure can prolong the life.

 

Of the brakes, you mean?

 

I don't recommend driving in tow haul mode unless you are towing. It will reduce your fuel mileage and cause unnecessary loads on trans components. Can also be dangerous driving with unloaded vehicles, tires can loose traction and skid under normal breaking. But that's just me you do what you like you're the one making the payments.

 

Yes

 

I've got just over 220,000 on my 2006 and **** near all of it with the tow/haul and e-brake engaged. My 2012 gets run the same way.

 

I use mine all the time. From the moment I turn the truck on and it gets warm.

Use it 24/7/365

It wont hurt anything, and will keep the slider nozzle working right.

The only reason I dont, is cause it doesnt do me much good anymore.
