It will use less gas. This will also allow ford to use bigger geared rearends, like 3.73:1 or 4.10:1 to let cars still have good mileage, but plenty of acceleration and such.
Anyone else also think its kinda crappy that once again ford is not letting you change the fluid in the transmission easily? I don't see how they expect ATF to last 200-250k.
I think it's wonderful, less maintanence works for me. My concern however is if this is like all the other "lubed for life" parts then it'll break.

Thats what I meant by crappy. By the time the transmission hits around 180k, the tranny fluid will probably be on its last legs, and if the vehicle is pushed hard, you an expect a premature transmission failure

Needs a lot of work, including some rot on the body, but shes getting there.
The permanently lubed ball joints is exactly what I was referring to. I just replaced lower ball joints and tie rod ends on my '99 Taurus with 95k on it. I suppose thats not too bad, however, the joints would have been fine had the boots not split open allowing the lube to escape.
That brings me to my point. Is the new "lubed for life" 6 spd going to a $3000 replacement item rebuildable ONLY by the manufacturer?
I think FMC needs to rethink and significantly improve it's warranty program and be prepared to stand behind what they build.

Okay, .88 vs 1.00. I don't call that a big deal. But what I do find remarkable is that low 1st gear. I could have really used that on my previous truck to get a load started on a grade. Now that I look at those numbers again, with that low gear in mind, that does sound really good.
The 1.00:1 gear is usually 3rd gear in a 4-speed auto. The 4.17:1 first and 2.34:1 2nd gear (almost the same as an AOD-E 1st gear) should make a massive difference in getting loads started. The .69:1 6th to .87:1 5th should also make drastic downshifts unneccessary when hauling loads up a grade.

Do you know which vehicle will use those ratios? Is that just for the F150 class? Or do you expect that strategy to be used in the Superduty series?

That applies to the new 6R80 and 6R60 trans. The Superduty's gearing will be a bit different.
I 've got news for you, my computer controlled 6 speed transmission on my 07 Ford Expedition sucks ass. Half the time the computer doesnt know what gear to pick and jolts you around. Mr. Ram Krisnaswami, a Ford powertrain engineering manager ought to come down to Texas and drive this crappy 6 speed transmission before he makes the kind of statements he is making. Sure if everything performed correctly it would work, I am just hoping the new F150 doesnt get the expeditions 6 speed transmission or the next vehicle i purchase may just have to be something other than ford.
The 6R80 trans is an extremely fine transmission, I've sampled it in several vehicles and it is just awesome. I suggest you try to find a new technician.
Hah! These new mechatronic 6-speed transmissions cost way more than $3000, double that at least.
It ain't just Ford, the whole auto industry is moving to this type of setup. More PCM control...
...? The whole industry moved to fully electronically controlled transmission back in the late 90s. The only thing new about 5 and 6 speed autos is that they put over drive on top of 1st, 2nd and 3rd gear to achieve more ratios

Please explain to me how the industry moved to "fully electronically controlled transmissions" back in the '90s when those transmissions still employed valve bodies.
And the differences you listed didn't even scratch the surface of the actual differences.

Think I'll go order a new Super Duty with a six speed manual before its too late and I have to put up with some computer shifting for me.I have a 5speed auto in my 06 5.4 SD and even though its been bullet proof I hate towing with it.Revs too high and never feels in the right gear..Manual for SURE with me next round...Even my 05 150 with a 5.4/auto tows better than it.But I'd rather have a stick in that one too if I had a choice...

All transmission still use valve bodies, but what do you think makes the valves move? All the functions of the transmission are controlled by electronically controlled solenoids. That is how they are fully electronic. Disconnect the harness from an electronically controlled transmission, and then put your vehicle in drive. Nothing is going to happen at all.
Also, there really isn't that much difference between ford's 4, 5 and 6 speed autos, at least the C3/C4 based designs. They basically added an over drive, later added an electronically controlled valve body, then later on they tweaked the valve body some more, added some more shift solenoids, and set it up to put over drive ontop of other gears to get more ratios.

yeah, you need to rev the 5.4. 3500 rpm and up is where it wants to be going up a hill. they were designed for those rpm's.

I dont mind the gas engine.Its quiet,dependable and does ok.And your right it does need rpm to pull..Its just that the auto tranny does not match it for towing like I think it should...Now the automatic in an 03 6.0 worked great for towing. I think its close to being the same tranny..But obviously the torque of the diesel matches it Way better.At least from what I have seen in my own. The 5 speed auto in the 6.0 was really the only automatic that I actually enjoyed driving because it felt like it was in the right gear in all situations..Drove that one in tow most of the time because it just seemed to work even more to my taste in that mode..
