FYI, for trucks requiring marker lights up top (anything over 80" wide), the amber color is law. With my F450, it's possible to get a maintenance ticket if any of my 3 front amber or 3 rear red marker lights or 2 front amber or 2 rear red corner lights are out.

I haven't been too aggressive on the throttle yet, waiting on some more break-in miles first. Under light-moderate it does skip gears on its way to 10th.

Note that Ford's 10R140 reverse ratio (4.695) is also lower than GM's new HD 10 speed 10L1000 reverse ratio (4.54).

And, the difference in reverse ratios within the transmission does not tell the whole story.

GM only offers a relatively tall 3.42 rear axle ratio with their 6.6L diesel, and to the best of my belief, only a 3.73 rear axle ratio with their new 6.6L gas.

Ford, however, while offering tall 3.31 and 3.55 and 3.73 axle ratios (vehicle configuration depending), also offers deeper 4.10 and 4.30 axle ratios, which futher multiplies the grunt effectiveness of Ford's 4.695 reverse ratio, bringing not only more power, but more subtle throttle control when backing a very heavy trailer.

The "2L" mod is certainly not going to be as popular (or necessary) with 10R140 trucks as it was with the 6R140

Bumping this thread back to page one in the hopes more will see it and let us know their first impressions of the new tranny.
It is enjoyable and reassuring to hear the positives so far. Hope they keep on coming!

10 Speed and MPG

F-350 Lariat, crew cab, 4x4, 6.7, SRW, long bed. 206 miles with 3.31 ratio. 10 speed is completely unremarkable. I just don’t notice anything from it and it is smooth. Remaining range from the onboard computer is 835 miles to empty with the truck unloaded. Better than 17mpg. Fair amount on highway. All in all, a MUCH nicer truck than a near identical 2013 F-350 DRW.

.......this isn't what I said.....
No doubt about that, particularly in fleets. Literally money going up in smoke. Anything you can save.... In my last assignment, I managed a middle sized municipal fleet (300+/-). Switching from the older CVPI to the new Police Interceptor (Taurus) saved thousands of $, even with the increase in the cost of the vehicles and upfits. Of course idling kills MPG, doesn't matter what is under the hood. 3-4 MPG increases saves big money in the long haul.

On a personal note, I replaced a 1996 F250 with a 7.5L/4EOD last December with a 6.2/Torque-Shift G. Old truck averaged 8 mpg regardless of whether I was pulling anything or not. I just topped 10K miles and averaged 12.2 mpg.

10K miles @ 8 MPG= approximately 1250 gallons of fuel. @ $2.25 a gallon, that equals about $2812.
10K miles @ 12.2 MPG = approximately 819 gallons of fuel for a cost of around $1844. That's a savings of about $968.

Of course, I'm still out $40K for the truck so its not like I "saved" anything.....
I also haven't broken down along I95 either.

Kinda wish I would have waited for the 2020 but happy as hell with the new one.

Got some miles on it now so wanted to update with some fuel economy numbers. With about 70% highway driving averaging 17.9 according to the truck.

Sounds good, how does that compare to your prior 6.7?

This truck and my previous 17 both have 3.55 gears so the only difference is the transmission and motor changes. The 2017 empty averaged around 17.5. One thing I will say is now that the ten speed has the learn strategy worked out it is an awesome transmission. Really smooth and shifts nice.

I test drove a 2020 earlier this week. Unfortunately, it was the exact opposite of what I'm looking for but it was the only 2020 on the lot. It was a 250 XLT CC 6.7 diesel, way bigger than my 350 XLT RC needs but I wanted to feel the trans. It was extremely smooth, I actually found myself checking the indicator to confirm the shifts, both up and down. Once, between 3rd and 4th, I felt a little....clunk..but I couldn't get it to duplicate. The turbo was kinda cool though...love the whine. I'm sticking with a gasser, gonna go with the 7.3 but after driving the 250, I do feel better about the new 10 speed.

Yes, my dealer put me in a '20 F 450 (as I have one on order) and all I can say is WOW. Lots of good today about the 450 but a highlight was the 10 speed, sifts like a knife going thru butter, in fact I had to look at the dash to tell when and what gear I was in,

Incredible response and with 10 spds it lives in the torque curve very tight which does several things: Unbelievable response to input, higher mpg and as smooth as a baby butt ride. Staying inside the upper part of the torque curve puts lot of power at your fingertips and I will it with an overall mpg of about 10%, yes, not much but a 1 mpg increase give you about 50 extra miles per tank on the 48 gal tanks (I have driven in and put 50.1 gal in the tank!)

You will love the 10 spd you get a better ride as a result.

I picked up my 2020 on 12-19-19 and so far have put 500 miles on it. 80/20 highway/in town. Transmission so far is very smooth and comparable to my old 2017 F-150 10 speed. You can hardly feel it shift under light acceleration, but you can feel it under moderate acceleration, although pretty smooth still.

I'm probably most impressed with the fuel economy, especially coming from an F-150 3.5TT. I did a 250 mile roundtrip drive on Saturday and averaged 20.0 MPG. F-250 CC short box, diesel, 3.31's, #1 diesel, cruise on 75, outside temp was 30-35 degrees, very little wind. The same trip in my EcoBoost would have been closer to 17.

So far, I love everything about it!

3.31 axle ratio is key to that fuel economy. And the super deep first (4.615) and reverse (4.695) ratios in the 10R140 enable the 3.31 axle ratio to still handle the GVW ratings, while remaining optimal for the most predictable usage, which is not that much over curb weight. That much seems clear, although not that much different than the F-150 10 speed, that has even deeper first and reverse ratios.

What remains to be seen in the fuel economy comparison between the 17 F-150 3.5L EB w/10 speed vs the 20 F-250/350 6.7L PSD w/10 speed are the average effect of regens over time. At only 500 miles, perhaps a regen hasn't even initiated yet?

What also remains to be seen is what folks seem to always find in the field on a first year introduction of a new piece of sophisticated electro mechanical equipment. If Ford manages to avoid teething pains in the first year, then the best finally CAN rest for a bit.

Agreed, only 500 miles is a snapshot of the 94,000 miles I had on my 150. Long term is key, but so far I'm impressed. To the best of my knowledge, it has not gone through a regen yet. My last diesel was the 6.0, so I've yet to experience one. I also noticed just filling up (580 miles now), that the DEF gauge is just now showing a bit of gap off of full.

Yes, buying a first year product does concern me a bit, but I did it with the gen 2 Ecoboost w/ 10 speed and had zero issues. I also felt better about the Powerstroke as it's the 3rd iteration now.
