2016 Ford Six Speed Transmission
Yahoo Message Number: 159379
Just read the following on another RV Forum. The RV was on a F53 chassis.

"Well, it turns out some people are experiencing an issue with the new 6 speed, me being on of them. Almost all trannys with a TOW/HAUL mode, will downshift on a downhill with just a tap on the brake. That will help maintain speed on a steep downhill. Turns out, some of the newer ones don't do that. Makes for a scary descent and some HOT brakes! Hopefully Ford recognizes the issue and makes the necessary repairs."

Just a note for your review and files.

Just a quick follow-up note. I thought 2016 six speed transmission on the F53 chassis ( 6R140 6-speed transmission) would be the same as on the 2016 E450. My little bit of research seem to suggest they were the same, but I may be wrong.

The 2016 manual says the transmission when in tow/haul "may downshift the transmission, slow your vehicle and control vehicle speed when descending a hill, without pressing the accelerator pedal."

No mention is made of tapping the brake or using the tow/haul button to downshift.

Gear choices are "P R N D 4 2 1".

As long as you can use the shift lever to control downshifting, over heated brakes should never happen... if you are paying attention.
Many dislike Tow-haul, due to the somewhat violent, unexpected down shifting and do not use it.
Most of us learned to control downhill speed using lower gears. It still works today, with or without automatic controls.

In the towhaul mode , when descending the hill, do you think the unexpected downshifting(which I experience as a rapid increase in rpms from 2500 to 4200 immediately)hurts the transmission or the engine? david 2005 IB 31 feet

My friends say that the engine and transmission are built to take the rapid downshifting in the tow haul mode and thus it does not hurt anything, but I agree it sure sounds terrible. david

I use tow haul mode almost all of the time. Even when not towing, we are near max weight for the chassis.
Why not let the gears help you with the load? I noticed that a newer U haul truck that I rented had tow haul as the default.

When we start down a hill, I physically downshift even though I am in the two haul mode. This keeps the heavy rpm downshift from being quite as significant.

I read that ford did not set tow/haul as default in order to present the best possible numbers to the EPA. I use it on as a matter of course as we are always above 13 K ( must be the dogs and their food).

David Miller, you asked..

Im sure with an automatic trans one would never go speeding down the hill and switch to a lower gears. That is what increases the rpms. If you see your going to approach or a sign that states a down hill grade, I'd slow down accordingly to the gear your going to down shift in. Then again, I don't have a tow-haul and don't know if one can turn it off if it's touchy..
