Off-road Mode.

BTW I read that the locking diff automatically disengages in ORM at around 25 MPH.

You read that incorrect...

Locking differential unlocks at speeds above 25 mph when off road mode is not engaged. It will remain locked up to the speed limiter (100 mph) when off road mode is engaged..

That is incorrect. It disengages when OFF. Stays locked when ON.

With regards to T/H mode I think it's actually a pretty intelligent system. When I've got a real load on (enclosed trailer) it will absolutely down shift after a brake tap going down hill. With T/H and no load it does not do this. How it knows I'm not sure but I use the feature all the time when hauling my trailer to save the brakes and not having to fool around with the +/- buttons.

The computer knows when you are towing a load when you have the trailer plugged in. It is only then the downshifting will occur when tapping the brakes.

Learned something else........Thanks BIRDMAN!!!

Good info for the Texas Raptor Run coming up.

It does this in T/H mode too I think. At least that was my experience when towing the other day.

in T/H you mean? In ORM tapping your brakes in a downhill coast will downshift. I've tried it numerous times.

It will downshift in TH without a trailer by tapping the brakes too. I use it all the time in Colorado.

Yes, in T/H mode. I've tried without towing, and I didn't think it worked. I'll test it tonight. Maybe it has to do with the grade of the hill?

Its like the hill assist... You have to be on a 3 degree grade for it to activate..

And i just tried tow/haul ass mode.. And it will downshift when you tap the brakes on a 3 degree hill or greater..

I just tried it too. On the flat it would not down shift. Could only get it to down shift when on a 4 degree hill.

Good stuff to learn.
