Here is a link for ten speed transmissions that supposedly will be used in the new 2020 Super Duty's. Hopefully I can post the link, moderator? https://www.tfltruck.com/2017/08/202...140-f250-f350/

Thank guys. I was wrong and I always like being wrong. I learn something when I’m wrong. Chevy is putting the 10 speed in their great 750 horse Camaro. The 6R140 is a great transmission. It will handle 1200 pound feet of torque. The 10 speed should be as good but I don’t see the point in it. My new F150 has the 10 speed and it doesn’t shift like I thought it would. I would have thought it would go through all the gears, 1,2,3,4,5,6,7 but no try 1,3,5,7. As yet I haven’t seen it use either second or fourth gears. It is smooth very nice transmission. I would think Chevy will also use it in their HD trucks. What I would still like to see is a large V8 Ecoboost engine. Say 6.7 with about 800 hp and 1000 torque. After driving a 2.7 EB for 3 years I’d be the first in line to get one. The 2.7 is an awesome little engine. I could have got the 2.7 EB the 3.5 EB or the 5 L and never thought about anything but the 2.7. I drove the 3.5 EB but liked the 2.7 better.
Have you saw Caddy’ new 550 horse 4.2? The standard version will be about 500 hp. When it goes in the mid engine Vette it will be 5.5 L with 850 hp. These are the good old days for performance cars.

The end of the 2020 year is when my 2016 F350 gets traded so I'll try it out.

I see no point in 10 speed transmissions in heavy duty trucks.Guess they are going to gear the rear end down to 5. something. I hear that those 10 speeds constantly hunt for the right gear when you put your foot in it to pass another car. Personally I would like to see it in a 2 speed rear end like big trucks.

Bone actually the two speed rear ends were common in older 1 1/2- 2 1/2 ton trucks like I used to drive while harvesting when I wasn't on a combine. Most big trucks used to use a main transmission and a Browning transmission which had three or four gears. I don't know for sure what is being used now but I do know that the big rigs use both automatics and manuals but I think the manuals are just a main 13/15 speed road ranger transmission. Somebody on here can correct me if I am wrong. Gear vender and another company used to make a two speed splitter for our somewhat older pickup trucks.

I hope somebody that has the tenspeed transmission could give us some insite. What I have heard is they skip gears when empty and utilize them when under heavy load like taking off from a stop or going up hills. I love my old 7.3 but would love at least two more gears so that the rpm does not drop so much between gears.

More info on the ford/GM 10-speed trannys.
https://www.forconstructionpros.com/...peeds-too-many

The goal is fuel efficiency and smoothness (shorter spread between gear ratios). I suspect the benefits pulling a heavy load are less apparent with diesels like the Duramax/Powerstroke/Cummins, since the torque curve tends to be relatively flat between 1000 and 3000 RPM.

I have a 10 speed in my 2018 F150 and had a 6 speed in my 2015 F150. The two trucks are nearby identical both are extended cab trucks both have the 2.7 Ecoboost engine. The 2015 was a XLT the new one a Lariat. The new one a little heavier by a couple hundred pounds. The 2015 had 325 HP 375 torque the 2018 325 HP and 400 torque. The 2015 was direct injection the 2018 direct and port injection.
The 2015 averaged 20.3 MPG over 36000 miles. The 2018 18.6 MPG so far but only over 200 miles. So there isnít much to learn there. It probably will catch up as the truck gets broke in. As far as the transmissions, I see very little different. The 6 speed used all the gears, the 10 speed skips gears. Iíve never seen it use second or forth gear.
Iím a member of a F150 form. Most of the people there are seeing about what Iím seeing, I think. Some prefer the 6 speed and some the 10 speed. Thatís like every thing, people like what they have. How many times have we seen that here? What hitch should I get? One like mine!
Overall I like the 10 speed but in a year Iíll know which I like better. I suspect it will be the 10 speed. We will see.
