If you think about it, the 6 spd never had trouble in 6th gear so odds are that 10th is just the overdrive gear when not towing. Not having driven one, my assumption is that the truck will pick 9th gear the bulk of the time while towing anything significant due to maintaining engine RPMs

So my 2015 4x4 lists 17/23 on the window and the gov site lists the same:

So wouldn't 17/22 be worse? Taking it easy around town I can get the city rating and even combined, but not sure I'll ever see over 21 on a pure highway tank. I wonder if the 10 speed will make it easier to get the EPA numbers.

According to that site the 2016 3.5 4WD was rated 15city/22hwy/17combined. So the new engine and 10-speed is a 2mpg bump across the board at 17/22/19.


By that same logic they list the 2WD at 16city/22hwy/18combined. If it's a 2pmg bump then the 2WD may end up at 18/24 and 21/22combined which isn't crazy but is an improvement.

That is the "GVWR>7599 LBS PAYLOAD PACKAGE". The regular 3.5L EB engine is rated at 16/22/18 (see the comparison here).

HOWEVER... I just learned that we are comparing apples to oranges here. It seems that the EPA has revised their rules for 2017, making MPG drop. Assuming 1 MPG, that would give you the 2 MPG bump compared to the 2016 ratings, or over 10%. I'd consider that pretty impressive.

I'm guessing the new mileage ratings will reflect real-world MPG more accurately. But only once the trucks get into consumers hands will we know for sure.

I was wondering about that. We had that up here from 14 to 15. A 14 was rated 29mpg and the 15 went to about 24mpg which is more reasonable but still an improvement real world. (FYI our gallons are bigger up here which is why the numbers are whack.)

There does seem to be some redundancy with the gear Ratios. But there will still be considerable difference between 9 and 10.
With 3.31 gears 9 will be about 1480rpm and 10 about 1366rpm at 60mph.
The only really odd thing I'm seeing is a big jump from 6 to 7 when the rest of the transmission is very small rpm drops between shifts.

Fairly confident that all engines will have the 10-speed, but they might only start with the 3.5 for 2017 to see how it goes.
