I have 1360 miles on my Tundra, and about 400 miles are in 4WD. I average about 17 miles a day in 4WD driving on the ranch.
Since ALSD is disabled in 4WD, I wasn't sure there was any traction aids in 4WD. I was pleasantly surprised to find that A-TRAC works very well. I found no mention of this in the owners manual and only one short mention of A-TRAC on Toyota's web site.All it said was that 4WD drives have A-TRAC, but no explanation of what it is, or how it works.
