Lsd
The 2IS does have a LSD option if you have a 250 automatic. None of the rest do. They have "pre-torque" which is a fancy way of saying they put a conical washer behind the pinion gear to preload it. The rest of the LSD function is up to the VSC and/or VDIM.

That said, I would like to see the performance comparison between the "electronic" LSD we got and a genuine LSD spool. I know I've used the parking brake technique a few times when I had wheel slip problems, and it does work well. It may just be a matter of speed of reaction, I'm not sure. It would be interesting to know for sure.

The best part is of this, is that the traction/stability control is so intrusive, that it's hard to imagine the LSD ever being utilized. It's like having a set of extremely strong legs, but being paralyzed from the weight down.

Correct. Although it's not so much the fact that the other IS' didn't get one. It's the fact that the IS 250 slushotippymagictronic did.
It's not automatically in the car, it's optional. And looking at the drawings in the New Car Features, it seems pretty unlikely it was laying around collecting dust. Possible, just really unlikely. Maybe it's a Tacoma part like the manual gearbox?
BTW, there is no way you could swap any of the 250 differential pieces into the 350. The entire rear subframe is different, the mounting points are different, and the internal dimensions on the 350's shell are different. Damn the bad luck, but it's typical Toyota.

The traction control system (VSC or VDIM electronic system) transfers torque by applying the brake to the spinning wheel and reducing engine power. The mechanical one simply transfers torque to the one that isn't spinning.

Why is mechanical LSD better? Simple: the electronic "LSD" kills performance.

I highly doubt they took a tacoma trans and put in the new is, this is not ford we're talking about here, the driving characteristics are total opposite for both vehicles and so are the enigine, very unlikely it's just a swap.
