6 speed transmission questions.
So I came out of the ice age and got a Suburban with the new 6 speed transmission (PRNDM_1). Reading the manual, it seems a little daunting. So how do you use it when towing? And what about steep...

What is the trailer braking feature? I did notice as I went downhill(not in tow haul) it did seem to drop down a gear on its own. I felt it downshift. What happens in t/h mode?
When going down a grade of any sort, the transmission will downshift to use the engine as a brake to slow the vehicle down. I'm going by memory here, but I believe on the GM's, tapping the brake once will initiate a drop of 1 gear, a second tap 2, and so forth. Or just hit the brakes sufficiently to control your speed, and it will drop gears appropriately.
Or use the "manual" shift control feature to manually drop to whatever gear lets you use the brake pedal only to adjust your descent speed and not control it.

It's called hijacking a thread. You wanted to talk about how great your Ford is, the OP asked about a Suburban.
Not really, to many people the Ford manual control is useless, and the GM manual function is mis-understood. ;-)
Anything more to add Tom?
