My 06 DCLB sport has none of these. Just a good old fashioned lsd, which is surprisingly tight for a factory unit with 55K plus miles (my truck was imported from the U.S.).
My wife's 09 AC TRD has vsc, dont think it has atrac, i dont drive it often.
What i did notice with her truck is that when we were on a logging road in the Okanagan, i couldnt get the tires to spin for very long.
I'm a little old school and maybe a little immature for my age but i really like chuckin my truck sideways and laying patches with it. seems you cant have any of this fun with all the atrac/vsc crap.
but like i said, i'm old school, i only accepted fuel injection when i had my diesel 60 series LC and discovered no burping on extreme slopes.
