Papifun, according to what I understand, you are correct. If you are going over 62, A-LSD will not engage and you will only have VSC operating, although if you have an 08, you can even turn off VSC in A-LSD mode, but VSC will still kick in in severe conditions.
Both the PDF's and the owners manual make it clear that they do not want us driving around on the highway in A-LSD mode. They don't say why, but they make it fairly clear when A-LSD should be used.
If I were driving on the highway in snow or other low traction situation I would leave the truck(2wd) in normal mode(no button pushed) This gives you VSC and TRAC operating. Both can and will cut your throttle and apply the brakes, (front and rear) to keep you going in a straight line.
I have found that when driving on dirt roads at home in 2wd and TRAC kicks in, it works as good as A-LSD as long as I don't fish tail, then it cuts my engine power.99% of the time, when I am on dirt roads(especially mine), I will be in 4WD, spinning tires causes wash boards which cost money, especially when I have 35 miles of road to keep up.

Its not that im guessing the computer kicks in, it does. I drive my Tundra, so i know its limitations. If you go into a drift hard in either direction, then use the momentum to drift hard the opposite way, I mean HARD, the yaw sensor lets the computer know, and sets off VSC. Itll do it in parking lots, or doing 120 down the highway. They really went overboard on these pickups. I love my Tundra and previos Tundra's, but i jes wish that i could get a real rear diff and no computer. Its bull ???? that i cant do a nut on pavement, but a Chev can.

You can't even with the traction control turned off?

no, with everything off, you dont have lsd, or fake lsd as it be.

By "nut", I'm assuming that you mean donut. With all the traction control off, you can do donuts on pavement all you want. Why would you need LSD for that?

i agree TOX..

on my truck only one tire goes like crazy, there is too much traction with dry ashphalt to break both tires loose and keep both spinning in a donut

how about a video clip for us.. would be nice to see and observe...

I agree. Tox, can we see your truck blow nuts? I know what mine will do, and its not camera friendly.

Heres a clip of my 86 Cressida drifter doin nuts.
