re: lots of gears in an automatic... the shop manager of a long time automatic transmission service company once told me, the more gears in an automatic, the smaller and weaker they are, and the more expensive to repair. I know people really love this new Ford 10-speed, but its not been out long enough to have any sort of reliability data. I for one tend to keep vehicles til they are past 250k miles so long term reliability and ease of repair are a big issue.

At least it can't cost you anything for the first 60,000 miles, by then you can know whether to trade it or keep it. If that ain't enough buy the extended drivetrain warranty. It is by far the single most popular truck ever built, and with unsurpassed reliability... resale should be ok.
My guess is that once you've bought one and your nerves have settled down you'll keep it.

If the question was worded, such as, "towing with a Gear Venders auxiliary overdrive", the answer might be different.

But the main point was more about running the engine that slow while doing work and the fuel economy that resulted.

Mikes comment didn't make sense to me since modern manuals are overdrive transmissions.
I think his point may have been, there is no torque converter unlocking and generating heat.

Just bought a new F-150. It has a tow/haul, normal, sport mode selector and a transmission temp indicator.

So now on a long trip I can play with it and see what works best.

I can tell you what works best for me. I use tow/haul mode always when towing. When not towing, normal mode is for regular driving, particularly highway driving or when I'm trying to maximize mpg. When I'm not towing, but I'm driving on uneven terrain/twisty roads, sport mode it is. Works well.

I agree about the backing uphill into a tricky campsite, but in traffic is where I prefer a stick. My new TV is an automatic and it took a while to get used to it in traffic. You have to brake instead of lifting, its annoying!

otoh, in heavy stop-n-crawl traffic, a stick is annoying, especially if you start getting muscle cramps in your clutch leg.

+10 the tow/haul mode is fantastic on the F150. I use it continuously when towing. The only time I don't is when I forget to switch into it after getting gas.

+10 on secondary roads around here. Zero shoulder whatsoever. You tend to PO other drivers MORE as passing here in the mtns is difficult. +10 Speeds vary from zero to 75MPH.

On the freeway, as long as you aren't in the passing lane, you are OK. That plus convenient gas, rest areas and more make the interstates my first choice. Choose your passing carefully, as you can become a nuisance to others, and its certainly time to speed up and complete the pass at a reasonable pace.

Bill, I'm picking up my 2018 the first week in March. The 2015 with the 2.7 has been just excellent, but it should be fun to try out tow/haul mode paired with a 10 speed.

You need the right gear box and the right clutch and you have to know how to use it. Manuals are stronger, more durable and they don't overheat.

Not so with Ram trucks.

Ram derated the Cummins diesel to 660 ft lbs and installed a weak clutch that will slip, if needed, so the stick can survive in their trucks. With the automatic, the engine puts out up to 900 ft lbs and the trans is rated for about 30% more than that. That automatic has a good lockup strategy and will not get hot in any situation.

The automatic is rated for much higher torque, and with it, the truck will do more work. The sticks are derated by over 200 ft lbs. to save the trans.

I don't know if any other manufacturers do the same, but it might be worth looking at when deciding to buy a stick or auto.

Hi: John in Santa Cruz... To OD or not to OD. That is the question. Sometimes I get cramps in my instep from holding my foot on the gas pedal but I don't like towing with cruise control on. Gotta draw the line some where on the second busiest freeway in North America!!!

I was just reading about this transmission. It was developed jointly by Ford and General Motors. We may have a Fordochev in the future.
