Question six speed transmission

Have any of you with the Axis/Vegas and 6 speed tranny noticed this?
On a down hill tranny is very quick to down shift if you touch the brakes.
It is slow to up shift after climbing a hill and reaching cruising speed, for us 62 to 65. Worse if in cruise. Doesn't seem to matter if you are towing or not.

Yes, I have noticed that it is slow to upshift after a hard load such as a hill climb, much longer than i think appropriate. 2016 Vegas 25.3

Yes...we experience same...
below is a clip from an article in Motorhome Magazine...

TORqSHIfT® AUTOMATIC OvERDRIvE TRANSMISSION AND TOw/HAUl MODE This tough, durable transmission features an efficient 0.71 overdrive ratio, a high-mileage internal transmission filter and 36 months/60,000 miles service intervals. The selectable Tow/Haul Mode helps reduce gear hunting, improves power delivery and uses engine braking to help control vehicle speed when descending

The downshifting is a feature: Tap the brakes and it downshifts. All Ford's do this these days (I noticed my wife's Escape do it when we were going downhill).

The 6 spd in my Axis is better down shifting and up shifting than the old 5 Spd in my Vegas. It's not a car - closer to a truck.

Is this when you have the "tow/haul" button engaged?

What would you want the transmission to do differently? Is it limited to upshift sooner without time delay?


Not having driven a 6-speed yet, I'm curious what you would change if you could. Your description sounds fairly typical of shift logic -- downshift quickly to provide immediate engine braking when needed (time delay would not be a good thing because it could lead to brakes overheating or accident), and a time delay (pause) when upshifting to prevent additional shifts in case the road turns uphill again. My guess is that engineers try to program transmission so that if you're climbing in a lower gear, and the road levels off for just a little distance, and then turns up again, that you don't end up upshifting on the flat, and then immediately downshift again. I think drivers would find unnecessary multiple shifts even more annoying.


For what it's worth, in the future (I would guess maybe 5 years ????) many vehicles will use GPS to identify road conditions (including grade and elevation) ahead of time so that the next gear needed will be anticipated before the vehicle gets there. That should allow for more efficient transmission programming while eliminating unnecessary shifts.

In the past, when fuel economy wasn't as important, engines ran at partial load more so, so having too many shifts up or down wasn't as big a problem. Gasoline engines today usually operate closer to full throttle for higher efficiency, so when a steep grade is encountered, it requires a downshift more often than in past.

Yes, "tow/haul" must be engaged for it to downshift when you touch the brake.

The coach should also downshift going downhill with the cruise control set. This happens without touching the brake and if you do tap the brake cruise control disengages.

I would recommend getting a five star tune, it helps tremendously with shifting and over all performance.

Ours does this whether in tow/haul or not. I have never had any truck that would down shift on its own when going down hill or if the brakes are touched. Also have never had one take so long to up shift once you get back to level terrain. Talked with a 4 Winds owner, 2016 model and it does the same. I think the shift points are wrong on the tranny.

Get a 5-star tune they will give you custom shift points if you'd like.

I had one in my F-350. It worked great pulling our old 5er around.
