I will be pulling a 10k gooseneck horse trailer with a F350 4x4 DRW CC 6.7 with 3.55 LSD. I like the idea of the tried and true 6 speed which seems to be a very good transmission but don't want to miss out on the next generation tranny if it's going to be all that much better. I'm concerned about the first year kinks too.
Any thoughts??

 

I wasn't aware the new transmission was going to the 6.7. I thought it was going to the new gas engine? Maybe I'm way off on this.

 

Ford is working on a 10 speed transmission for the heavy duties. Probably 2020. If they do come out in 2020 I would wait a year or two after that to make sure all the kinks are worked out.

 

If you need a truck now or next few years got the 6 speed. It is proven durable and reliable especially for a 10k trailer.

If you can wait 5+ years then wait until the new 9/10 speed has been "field" tested by others. I wouldn't get the 2020 model year, maybe 2021...

Personally the 6 speed is what I would want. Less complicated. Already available now. I would also expect minimal (if any) MPG gains vs the 9 (these trucks are bricks, doesn't matter how many gears you have). When towing the difference will be even less.

 

thanks all the the replies, I feel the same way, 2019 it is for me.

 

Buy now, enjoy now.

 

If it's anything like the F150s, wait a year or two after the 10 speed comes out.

No major issues, but definitely some first model year issues with erratic shifting, etc. The 10 speed is nice, but the 6 speed works just fine for what I need it to do in my F150.

 

 

You obviously don't work in product development of any kind.

 

 

The new transmissions for MY2020 Super Duties will be 10 speeds, not 9.
They will be the 10R-140, 10R-100 to replace the existing 6R models.

 

I will probably be ready to trade my '17 6.7 6 speed for a new truck by 2021.

The 10 speed will certainly be an improvement but the 6 speed can hardly be faulted. The 6.7 makes so much torque its hard to fault the 6 speed's operation.

 

 

Sorry to hear about your troubles. My '17 F150 10 speed has been flawless. We pass people towing our RV up the side of a mountain due to always having the right gear, and engine braking on the way down has saved my brakes. On a recent highway trip, we got 30.5 mpg over 500 miles with the 3.5 EB.

 

I drove an F150 loaner truck with the 10 speed, I can honestly say I did not much care for it, seemed like it was always shifting, I much prefer my 6
