2020 MPG?

I'm pretty set on replacing my '04 F250 CCSB 4x4 with a '20 F350 CCLB 4x4. I love my 6.0 but my trailer is about to put on several thousand pounds. I don't think I need the 100tq increase from the '19 model year, but I'm 90% sure I'm holding out to get the 10spd in the '20. How much increase in fuel economy do you think it will pick up over the 6 speed? Will it make towing grades a lot easier?

Cheers,
Jon

Im not sure if the MPG will change much for highway cruising. This is just my total speculation but Im guessing its more in-between gears and not much change from final drive ratio for the top gear. I don't think ford has put out final drive ratio's yet. Again this is just my guess. Im guessing having more gears will help with towing a grade and keeping the RPM in the sweet spot for towing.

I can’t vouch for the 2020, but I will say I’m impressed with it in our Raptor. We just offed the 2015 with 3.5 EB 6 spd 3:55 For the Raptor 3.5 HO 4:10.

We are getting the same if not a little improved MPG and I have nothing but a big grin mashing the pedal every chance I get. So, here’s hoping the 10 in the Super Duty’s does the same.

The modes is enough of a sell as well. The slippery mode is awesome, and I understand it carries over to the Super duty.

Towing will be night and day different! I've towed with a 6.7 once and it was a dream compared to my old 6.0. I still loved the 6.0 since I never towed heavy but if I did then a 6.7 would have been in my future.

I'm thinking my mileage will be better than my 2017 due to the following:

I run back and forth to my lakehouse at least three times a month. The trip is 200 miles each way. I drive 75-80. My current 2017 F250 has a 3.55 rear end gear (which most did with the 6 speed); the new one has a 3.31 rear end gear. If a person wants a 3.55 gear now-you must order the heavy duty towing package. Ford has done this due to the addition of the 10 speed; the truck doesn't have to have the 3.55 to tow the same as weights as it does with the 6 speed. Finally, the transmission gear reduction in 10th gear is slightly more than it is in 6th gear with the current transmission. All of this translates to lower cruise RPMs at my above listed cruising speeds. At 80, I'm almost right at 2K RPMs right now. I think I'll be closer to 1700-1750RPMs with the new truck-which is a range these engines seem to be more comfortable at...

isn't 3:31 available with the 6 speed?

Yes it sure is there if one wants to order that gear set from the factory.

I don't think mileage will increase at all with a 10 speed. Final gear lock out will still be around 45-50.

Like others have stated, its to keep the engine RPM in its sweet spot.

Your thinking of having it shift up around 70 mph to its final 10th gear is wrong. The additional gears are being used to keep engine rpms up so it doesn't lug down when towing or accelerating.

That being said. I have a 2019 with a 6 speed at 3.55 rear end. unloaded cruising at 65 MPH i get 21-22. My old 6 leaker, I was down in the 16-17.

These new 6.7 ford trucks are night and day difference compared to your current 04 6.0. I made the switch and its unbelievable how this new truck out performs that old 6.0.

My assertion above is that I should have better highway mileage, and don't think it is debatable for the two reasons I cite:

1. larger gear reduction for the 10th gear than the 6th on my current tranny
2. The 10 speed essentially rendering the 3.31 rear end gear as the "default", versus the 3.55 being the default with the 6 speed.

I will not be spinning the same RPMs for 3 hours each way at 80 MPH.

I pick it up tomorrow, and will be able to verify.

False. The more gears you have, doesn't mean they lock out at an early speed like that. A year ago I rented an '18 150 with the 10 speed and I never saw 10th come up at all. My Jeep is an 8 speed, if I'm cruising around town 40mph or so, it won't just go to 8 and call it a day. Often times around town it will be in 5th or so cruising. Even on the highway, if I'm doing 80, it could be in 7th gear because it's happy there. If I shift into 8th myself, then put it back in auto, more times than not kicks back down to 7th because that's where it wants to be. I would think this follows suit from the 150 side.
