Alright guys! I finally said to myself get out there and figure this out. Having listened to all of you and considered the manual and wondering what was going on. The e-locker works awesome. It kicks off after you get over about 20mph and re-engages when you drop under that or stop. Almost should just leave it on! The shifts from hi-lo, as Shotgunz pointed out, were flawless when barely rolling (practically no activity on the speedo needle) and shifting to neutral and then making the shift. Sorry I've taken up so much of this thread...but I've always wanted to know exactly what I've got before I go boasting to those poor Gov't Motors people or the rice burners. ; P

I was pulling out of my driveway tonight pulling a trailer. The driveway is uphill, and has 1to2 in of snow and ice. Trailer only weighs about 800 lbs. I had to come to a stop at the street because of traffic and when I tried to start again, my rear started to spin my 20" Pirellis. All of this to be expected under the conditions. I stopped and was about to put it in 4x4 but instead decided to see what the traction control would do. Although it wasn't the smoothest, it did get me up my driveway and out into the street. At that point since all of the roads are ice and snow covered right now, I put it in 4x4, but I was satisfied with the traction control for that test. It did exactly as it was supposed to.
I don't know if I said this before but I love this truck.

I can confirm binding on my FX-4 when if 4x4 mode. On a couple of occasion, felt and heard the binding when make sharp turns while driving. Overall road surface was wet with slight snow since it was recently plowed and salted. However, if you are making a sharp turn, it will bind, which to me, confirms at least the front wheels are locked.
Also, as for a as the overall 4 wheel traction in 4x4. My drive-way is on 15-20 degree incline and was un-plowed with about 4-5 inches of snow. The FX-4 was in 4x4, without the e-locker engaged, drove right up it without a single slip. My wife’s Honda Odyssey, front wheel drive, struggled and spun tires trying to pull it up the driveway. Really have yet to use the e-locker except a couple of times pulling boat out of lake.

Normally a locker will only be put into vehicles with a solid front axle, and more often than not, on vehicles used for mud running in fairly straight lines or snow plows.
