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.
The 6R transmissions do not use valve bodies, they do not have any mechanical valves to control fluid flow. The 4R70/4R75 and 5R55 trans had regular old automatic valve bodies with a couple solenoids used to activate valves, the Ford 6R, ZF 6-speed, and the CVT all use mechatronic assemblies that have the TCM, modules, turbine shaft sensor, temp sensors etc. integrated into the mechatronic assembly with NO mechanical valves.
The new 6R trans are also very different from the older trans in that they don't have any one way clutches. All upshifts and downshifts are contolled electronically.
So yes they are drastically different, and no the '90s transmissions weren't "fully" electronically controlled. You also can't group the Ford 5R and 6R together, as the 6R is a completely clean sheet design not based on previous designs.
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...
could be searching for a gear if the rear end is to low of a grearing

Gearing is very close to the stock 3.73s it came with.. I switched to a taller 315/70 by17 tire and compensated by switching to 4.30 gears..I actually wish I would have went for the 4.56s instead. Yes you get more total rpms but it pulls through each gear easier to get you up to speed..
If the current trannys use a 2.84 1st gear and the new 6 sp. uses a 4.17 1st gear, we now have a granny gear. Look at the 6 sp spread between 1st and 2nd...from 4.17 to 2.34? The truck will fall flat on its face from 1st to 2nd. Too much rpm drop between shifts. 2nd should be around 3.00, and 3rd should be around 1.70...

You are forgetting about the torque converter. Plus, of the torque band on the engine is wide enough, it shouldn't be to much of a problem

Needs a lot of work, including some rot on the body, but shes getting there.
The TQ has nothing to do with the spread between gears...and the spread between 1st and 2nd (6sp) is far greater than the spread between 1st and 2nd on the current trans. There won't be that much of an improvement in torque to accomodate that much spread between gears.
The only way mileage will change significantly is with a taller final drive ratio (or make it much lighter)...like 3.00-1. The low first gear will let the truck act like and accelerate like it has 3.73's...until it shifts to 2nd...!!!
Give me a manual anyday. They spend all this work, money, etc, to give you something comparable to a manual and its going to probably be more likely to fail with the lifetime fluid... I'm with the earlier poster, better get your SD now while you can at least still get a 6 speed manual.

yea the spread is greater in the new trans but look at the overall numbers the new 3rd is comparable to the old 2nd and the new 4th is lower then the old 3rd, plus the 5.4 make 292tq at 1k rpms its gonna pull fine, heres the tundras 6spd
1st 3.333
2nd 1.960
3rd 1.353
4th 1.000
5th 0.728
6th 0.558
i like fords spread much better, but either way its gonna be much better especially with 373, those seem perfect with the new trans
1st 4.17:1 Look at the spread between 1-2...1.83 !!!
2nd 2.34:1
3rd 1.52:1 .82 spread between 2-3...much better
4th 1.14:1
5th 0.87:1
6th 0.69:1 The rest of it looks good.
Reverse 3.40:1
Toyota ratios
1st 3.333 A spread of 1.37 between 1-2
2nd 1.960
3rd 1.353 .61 spread between 2-3
4th 1.000
5th 0.728
6th 0.558
That close ratio trans is part of the reason why the Toyota whips our ass in a drag race. They keeep the engine in the middle of the power band. Combine that with more hp and less weight...
Ford needs to put the 150 on a diet. Lose 1000 lbs and see where the performance and mileage goes.
I'd be willing to bet that when you come to a stop this transmission will go to 2nd gear for regular starting. The only way to use 1st gear will be to shift to it manually or if you are in tow mode.
That's my guess.
If that is the case, the difference between 1st and 2nd won't be a factor.
If I'm going drag racing, I ain't taking a f 150 to the race!

Well, maybe...but the current low gear ratio is 2.84. If the 6sp takes off in 2nd, that ratio is 2.34...that's a tall gear to get started in...
And I agree with you about the don't take our 150's to a drag race...!!! I love my 04 FX4 Scab, but it ain't real fast...!!!
I enjoy chatting it up when there ain't no fighting...a fun topic!!!

Anyone out there have a NICE 2002-2003 F150 Supercab 4wd for sale with a 4.6 and a 5 speed manual??? Nuff said..Might have to force induct it to get the power but its will be a fun truck when your done..

LOL....now thats just dumb....theres plenty of them used as everyone who actually goes and drives a new truck knows they've got more power, ride better, tow and haul better and are worlds comfier....You should have no problem finding an old 02-03

With a 5 speed? They are pretty darn rare. At least around here. And you cant even get new ones with em (w/ a v8), thats whats turned me off to newer '150s. Might just have to get a 250 while they are still offering a manual there!
