Looking for a bit better traction in slippery conditions. Anybody have experience installing Eaton Detroit Truetracs? If the 2002 Sequoias have "A-Trac", it seems to be pretty primitive and not terribly effective.

I have owned them. For me - they are the only type of limited slip I would put in an offroad vehicle or truck. They work really well as far as limited slip diffs go. They are not really on par with a full locker for more challenging terrain, but are great in mud, snow, ice, etc. I haven't had them together, but I think they would play very well with ATRAC. For a differential that isn't selectable and if you don't need a full locker - I think it's an excellent option. In a rear application you'll never know it's there on the road and it'll be a big improvement offroad.
I've actually said a few times that MTS/ATRAC in my 5th gen 4Runner is very similar to a truetrac. They feel almost the same in a lot of cases.
Watch a few videos on light brake application and how much it helps with the helical limited slips. It works surprisingly well for that type of diff in some situations. IIRC all 1st gen Sequoias have ATRAC that is pretty mild and only engages in 4low under 2k rpms. Even a very mild ATRAC function would make a pair of truetracs function very close to having full lockers. I've thought a lot about adding them to my gen2 Tundra except that it has a front ADD diff, so they don't really work well with the way that the system is designed to freewheel one side of the diff spider gears in 2wd. May be a minor issue in a Sequoia when you run in 2hi - it would just spin the full diff all the time and not save as much fuel.
