But what Soccer Mom driving AWD truck may do? She gets in stuck, press gas pedal and digs in mud ore snow, then she understands that it is time to engage AWD, floor gas againe, dig front axe in, then locks all the axe diffs, shift T-case to low and asks someone to push her out. Truck runs, accelerates and she forgets to disengage AWD, LOW and DIFF Locks.... She tries to drive truck in curve, trucks skids, she turns steering wheel panicly, press brake pedal (but nothing like ABS, EBD, ESP) can help her to controll truck and..... some wrecked exotics.... 
So Ford think it is not good and makes simple ore sufisticated AWD systems.... Early with Dana all time AWD electronically locking, later cars have torsen ELSD (Volvo likes torsen....). Less reliability, more expenses, less off road ability, but more safety... to compensate Soccer Mom's irresposibleness.....

Fortunately, most of the Soccer Moms never get off the pavement. The ones that do are either rural people who are used to driving in bad conditions or they shouild have known better and they pay the price.
Unfortunately, Ford or the rest of Detroit has never seen fit to use controllable locking differentials. I gues it interferes with thier cell phone conversations.

Actually the method Ford uses to soften the shifts is by pulsating the engagement solenoids instead of engaging them outright. The pulsation is done electronically but if you use a shift kit, the increased pressure ensures that it fully engages anyway. The pulsation is the reason the bushing kits help, they fix the wear, and resist future wear causing by the buzzing solenoids.
I was under the impression that the harshness of the shift in all the electronic controlled Ford trannys was controlled by the computer or control module. I have a '93 E-350 van with an IDI 7.3 diesel. It has no electronic control on the engine but it does have an ECM on the tranny. It does sense the RPM of the engine and the throttle position. If it looses either input, it goes into a safe mode with a shift like a jack hammer. The tranny on my '03 F-350 6.0 diesl is extremely controlled down to the oint where it actually learns your driving and towing habits and operates the tranny accordingly. I wouls assume that since the 5R55E is electronically controlled they would have used pulses to the valve solenoids to control the shift.

they consider controllable locking diffs to be a proffesional thing. they prefere to use traction controll. When one wheel slips brake control unit apply brakes on this wheel and transfers torque to other one throught diff. If it is not enought brake pressure to prevent skidding Brake unit asks engine controll unit to decrease torque. But this system works if engine has electronically controlled throutle and "electronic" gas pedal. but these suffisticated system ford offer in the USA with Volvo logo.
In USSR/Russia controllable locking differentials are professional things too. For example on military trucks/trunsporters they use self locking diffs (they think dumb soldier wont do all well especially in action).

On another note I don't think ford puts LS in the front of vehicles as far as I know. Maybe in the 80's Not in trucks for many years..

Tons of info on Ford trannies here:
Main Tech Help Page - Baumann Electronic Controls, LLC
From that site: "The A4LD was the first Ford transmission to use an EEC-controlled torque converter lock-up clutch and later became the first to use electronic shift control (via a 3-4 shift solenoid). The French-built A4LD was created by adding overdrive to the front of the C-3 three-speed unit. "

Sorry, but you wrong there. Come on over and I'll show you three of them and I've got the window stickers from two of them to prove it. My '89 F-350 and my '94 F-350 had it and so does my '03 F-350. I'll have to look and see if I can find the window stickers and scan them for you. In all cases they were optional. It was even on my first Bronco I ordered in '73. If you ever drive one with it and try 4WD on dry pavement you will know it. They don't like to turn.

I don't think so....jack up the front lock in the hubs and see if both tires spin the same way.. Not from the factory And never an 03 it wasn't an option. On the super duty forum I remember a couple of the ford guru's saying definetly not to LS's in front ever being and option...Thats my story and I'm sticking to it ...LOL
On edit I stand corrected The dana 44 80's into 90's had the option.Didn't know that... That was the only one and was rare...super duty no never...

The older A4LDs use the governor, vacuum modulator, and other hydraulic systems to control firmness. Increasing line pressure has the same effect however.

Ones I did something wrong and 3rd engaged with jerk and to make it shift smoothly I had to release gas pedal when tranny shifted and when 3rd was engaged i pressed gas pedal to go on accelerating

Oh BTW, If you know how to order and your salesman isn't brain dead you would be surprised what you can get from Ford. Everything I have ordered has had stuff that was not a listed option. It is also possible to have standard stuff deleted by this same ordering process. Ford won't list front LS because they don't recomend it. That DOESN'T mean they won't do it if you know how to order it. All our 4WD veicles we have ordered from Ford for the last 40 years have been special orders. It usually just takes twice as long to get them.
